Abstract
Many important materials throughout the world are composed of a variety of textiles, which are stored and presented in museum collections, galleries, and libraries. These textiles are one of the most important elements of cultural heritage and interpret essential objects that document the past human life, artistic creations, international trade, agricultural development, technological developments, and their cultural and social values.  As a result, it is necessary to study and apply suitable methods to protect and conserve these kinds of unique heritage textiles for our future generations. The method of conservation of these cultural-historical textiles is one of the most versatile branches of conservation and depends on various parameters. A number of bio-deterioration of cultural-historical textiles and also the disadvantages of conservation methods on these objects, human health and the environment, show the need for evaluating the bio-degradation mechanism of different microorganisms on these kinds of textiles and the use of latest methods for their conservation. In this way, the present work aims to investigate how cultural-historical textiles have been degraded, as well as the latest conservation methods. To achieve the purpose of the research, the qualitative content analysis method was used. The main research questions are what is the mechanism of biodegradability process of textiles? What is the importance of nano technologies in the protection of historical textiles? The results showed that one of the newest and most effective methods of protecting cultural-historical textiles against erosion caused by biological factors is the use of nanomaterials. These panicles have been intensively studied for various textile applications and demonstrated to provide multi-functional performance such as self-cleaning, release of dirty, protection against ultraviolet rays, antimicrobial properties, long-lasting, and multi-functional performance without compromising the intrinsic properties of the textile, which can be utilized to protect the cultural-historical textiles and slow down their degradation processes.

Introduction
Since prehistoric times and in all cultures, textiles have played an important role in the traditions and life. They have been considered one of the most important elements of cultural heritage that in different periods of a country history have usually been a number of antique textiles, such as decorative and artistic fabrics, clothing, carpets, tapestries, ecclesiastical vestments, woman’s belts, bags, and paintings. They are mainly obtained from tombs, archaeological excavations, mansions, crypts, sunken ships, and churches. Although, these valuable textile artefacts interpret essential objects that document the past human life, artistic creations, international trade, agricultural development, technological developments, and their cultural and social values but they are considered to be degradable materials due to a combination of various pollutions, biological, physical, environmental, and chemical parameters. The challenge has been to develop effective strategies for the conservation of these cultural-historical textiles, considering the strategies depend on several factors such as storage conditions, textile ages, the chemical types of their fibers and also their history period of use. There are different chemical and physical methods to protect from the historical textiles (Gutarowska 2017: 2388-2406; Karbowska 2011: 223; Sequeira 2012:  67; Valentin 1999: 85; Wirtanen 2003: 293). Nowadays, nanomaterials and technologies are becoming more important than the physical and chemical methods due to their multi-functional performance such as self-cleaning, release of dirty, protection against ultraviolet rays, antimicrobial properties, long-lasting, and also due to their multi-functional performance without compromising the intrinsic properties of the textile, which improves the conservation process of cultural- historical textiles and slow down their degradation processes (Lite et al., 2022: 610; Gutarowska 2014: 277; Lite et al., 2022: 609; Zambrano et al., 2020: 9817; Syafiuddin 2019: 794).
Following this tendency, there are several worldwide studies available on this regard but very limited studies have been done in Iran. These studies have been mainly investigated the effects of optimal environmental conditions, the atmospheric pollutants, and ultraviolet rays on the conservation process of textiles (Kianoush 2008; Samanian and Bahmani 2018; Hamzovi 2019). This is in while; the majority of Iranian studies have various drawbacks in terms of evaluating the bio-degradation mechanism of different microorganisms on the historical textiles and the use of latest methods for their conservation. In this regard, the present study attempts to disclose how cultural-historical textiles have been degraded, as well as the latest conservation methods by using descriptive and analytical method and also based on library information. 

Discussion 
The term biodegradation is defined as an irreversible process leading to a significant change of the material properties by the action of vital activities of microorganisms (through enzymatic or metabolic action)، (Zambrano et al., 2020: 9789). This biodegradation of organic compounds frequently causes the conversion of many of oxygen, carbon, nitrogen, phosphorus, sulfur components in the primary molecules to the inorganic products and also creates of new cell material. In general, stages of biodegradability of materials can be expressed in the following (Fig. 1)، (Nofal 2022: 5-6):
A) Primary stage: Substance chemical structure alteration resulting in substance removal of a definite property.
B) Environmentally acceptable stage: The biodegrading process to the extent of elimination of specific unacceptable compounds properties. This process is similar to the primary biodegradation approach, and it depends on the environmental conditions.
C) Ultimate is full compound decomposition or breakdown into simple molecules fully reduced or oxidized (such as CO2/methane, nitrate/NH4+, and H2O). 
The textile biodegradation process depends on the composition of the findings and the storage conditions and can occur slowly or quickly in the three following stages: 1) bio-deterioration and bio-fragmentation, 2) assimilation, and 3) Mineralization. (Lite et al., 2022: 608). Microorganisms digest the organic products of plastic degradation under aerobic or anaerobic conditions (Zambrano et al., 2020: 9790). The process of decomposing organic matter in the existence of oxygen is called aerobic bio-degradation. Anaerobic respiration is the practice of decomposing compounds by the action of microorganisms in oxygen absence and bacteria and fungi use the acceptor of an electron other than O2 as a chemical entitle (Nofal 2022: 7). 
Nanotechnology is revolutionizing materials science in a pervasive way, in a manner similar to polymer chemistry’s revolution of materials science over the preceding century. The continuous development of novel nanoparticle-based materials and the study of physicochemical phenomena at the nanoscale are creating new approaches to conservation science, leading to new methodologies that can “revert” the degradation processes of the works of art, in most cases “restoring” them to their original magnificent appearance (Giorgi et al., 2010: 695). The most intensely studied nano-structures for textile artefact conservation are metal nano-particles (AgNPs), metal oxides (zinc oxide, magnesium oxide, and titanium dioxide), hydroxide nanoparticles (calcium hydroxide and barium hydroxide) and modified nano-clays due to their remarkable antimicrobial properties, UV-absorbers, water-repellents, and dirt repellents (Lite et al., 2022: 609; Giorgi et al., 2010: 702-703; Palladino et al., 2020: 3). 

Conclusion
Our country, with its ancient history, is one of the most important centers with rich cultural-historical works in the world. A large part of these works are textiles which can be degraded using microorganisms due to their chemical structure. More and more studies are necessary for the field of historical textile conservation to preserve the memory of our predecessors, maintain up-to-date knowledge regarding new methods, and for future generations. Most of the studies conducted in Iran, have been investigated the effects of optimal environmental conditions, atmospheric pollutants, and ultraviolet rays on the conservation process of textiles. This is in while; the majority of Iranian studies have various drawbacks in terms of evaluating the bio-degradation mechanism of different microorganisms on the historical textiles and the use of latest methods for their conservation. In this way, the present work attempts to take a step towards the existing gaps. According to the results of this research, it can be concluded that the term biodegradation is defined as an irreversible process leading to a significant change of the material properties by the action of vital activities of microorganisms. This process occurs in the three stages i. e. bio-deterioration and bio-fragmentation, assimilation, and mineralization. The mineralization catabolic pathway depends on the environment where the microorganisms can grow and they digest the organic products of plastic degradation under aerobic or anaerobic conditions. During both processes, aerobic or anaerobic, microorganisms need a carbon source for growth and reproduction. 
In order to reduce the biodegradability of textiles, several physical and chemical conservation methods have been reported in the literature. The main method of preservation is maintaining the findings a microclimate to limit degradation by adjusting the brightness, humidity, and temperature of the area in which they are stored or exposed. Recently, special attention has been given to nanomaterials. Nanotechnology is revolutionizing materials science in a pervasive way, in a manner similar to polymer chemistry’s revolution of materials science over the preceding century. The continuous development of novel nanoparticle-based materials and the study of physicochemical phenomena at the nanoscale are creating new approaches to conservation science, leading to new methodologies that can “revert” the degradation processes of the works of art, in most cases “restoring” them to their original magnificent appearance. The most intensely studied nano-structures for textile conservation are metals, metal oxides, hydroxide nanoparticles, and modified nano-clays due to their remarkable antimicrobial properties, UV-absorbers, water-repellents, and dirt repellents.

Abstract
Iranian architects often designed structures to serve multiple functions beyond their primary purpose, a practice heavily influenced by Iran’s hot, arid climate and long summers. This multi-functionality is most evident in water-associated architecture, particularly in Isfahan’s historical bridges. Despite extensive research on Isfahan’s architecture, this specific aspect of its bridges has been understudied. This research aims to re-examine the non-transportation functions of four Isfahan bridges: Pol-e Shahrestan/Ji, Pol-e Allah-Verdi Khan/Si-o-se-pol, Pol-e Khaju/Shahi, and Pol-e Jubi/Sa’adat-Abad, highlighting their role in ceremonial and environmental landscape architecture. Main Research Question and Hypothesis: The study investigates how and why ceremonial functions were integrated into these bridges. It hypothesizes that this practice was inspired by Indian Jal Mahals (water palaces), introduced to Iran via extensive political and cultural exchanges during the Safavid era. Research Method: This study employs a historical-descriptive approach, with data gathered through documentary research and analysis of historical sources and travelogues. The findings indicate that while the concept of ceremonial water pavilions (Cheshmeh Emarat in Iran, Jal Mahal in India) pre-existed, its application on bridges was an innovation in Safavid Iran. The bridges served as ceremonial platforms for royal events like the Abrizan (Water Sprinkling Festival), receptions for ambassadors, and public spectacles. Furthermore, they played a crucial role in microclimate moderation by creating reservoirs that increased humidity and helped recharge underground aquifers, addressing critical environmental needs of the capital city.

Introduction 
This paper explores the multi-functional design of Safavid-era bridges in Isfahan, which extended beyond mere river crossings to incorporate significant ceremonial and environmental roles. This architectural ingenuity was a direct response to Iran’s challenging arid climate and the socio-political ambitions of the Safavid court. The study focuses on how the bridges Pol-e Shahrestan, Allah-Verdi Khan, Khaju, and Jubi were integrated into the urban and royal landscape. While the paradigm of the water pavilion (Cheshmeh Emarat) was known in Persian and Indian (Jal Mahal) architecture, its adaptation onto bridge structures represents a unique Safavid development. This research addresses a gap in the existing literature by systematically analyzing these bridges not just as feats of engineering, but as central elements of ceremonial life and environmental engineering in the capital.

Materials and Methods 
This research is based on a historical-interpretive methodology. Data was collected through meticulous documentary research, including analysis of primary sources like European travelogues (e.g., by Chardin, Tavernier) and Safavid chronicles. Secondary sources encompass modern scholarly works on Safavid architecture and urbanism. Architectural analysis was conducted by examining historical plans, photographs, and existing structures to understand the form and function of the pavilions. The comparative method is used to draw parallels between the Iranian Cheshmeh Emarat and the Indian Jal Mahal tradition, tracing potential routes of cultural and architectural influence during the 17th century.

Data and Findings 
The investigation reveals distinct evolutionary stages:
• Pol-e Shahrestan: An older bridge onto which an octagonal pavilion (Hasht Behesht plan) was added during the Safavid period, representing an architectural annexation rather than an original design.
• Pol-e Allah-Verdi Khan (Si-o-se-pol): Built by Shah Abbas I, its primary function was connectivity. Ceremonial activities were initially held in the vaulted spaces beneath the bridge deck due to structural constraints, serving as a royal loge for the Abrizan festival and receiving dignitaries.
• Pol-e Khaju: Constructed by Shah Abbas II, it represents the pinnacle of this integration. Two central pavilions (Beyglarbeygi), adapting the Hasht Behesht plan to the bridge’s axis, were purpose-built as ceremonial platforms. The bridge could be dammed to create a vast lake for boating, fireworks, and reflections of upstream palaces like Ayeneh-Khaneh.
• Pol-e Jubi: This bridge provided private access to royal gardens. It featured a central pavilion (now destroyed, but documented in European engravings) similar to the one on Pol-e Shahrestan, offering the royal family a secluded vantage point.

Discussion 
The findings confirm the hypothesis that the sophisticated development of bridge-pavilions in Safavid Isfahan was influenced by cultural and political exchanges with the Indian subcontinent, where the Jal Mahal tradition was well-established. The Safavids adeptly synthesized this influence with pre-existing Iranian concepts like the Cheshmeh Emarat and the ancient Abrizan festival. This discussion argues that these structures were not merely aesthetic additions but vital components of urban infrastructure. They served as instruments of royal propaganda, stages for displaying sovereign power to both the public and foreign emissaries. Furthermore, the creation of artificial lakes through damming was a brilliant hydrological strategy. It addressed Isfahan’s environmental needs by significantly moderating the microclimate through evaporative cooling and critically recharging the subterranean aquifers that supplied the city’s water via qanats.

Conclusion
In conclusion, the historical bridges of Safavid Isfahan exemplify a profound integration of multifunctional design. Iranian architects, responding to climatic necessities and royal ambition, masterfully extended the function of these structures from mere utilities to complex ceremonial platforms and environmental regulators. The practice of adding pavilions to older bridges or incorporating them into new designs was a strategic innovation in the landscape architecture of the era. While inspired by the Indian Jal Mahal, the Safavid implementation on bridges was an original contribution. These structures became iconic urban elements, central to the city’s public ceremonies and essential to its ecological balance. They stand as testament to a holistic architectural vision where utility, ceremony, and environmental technology were seamlessly woven together, defining the grandeur of Isfahan as a Safavid capital.

Abstract
Undoubtedly, the southern area of Tehran province, which has been formed in the fourth region over time, especially in the late Islamic centuries, based on historical sources; It was always of great importance for the governments of this era from the point of view of geographical and political location. One of the reasons for the importance of this area was its location on three important communication routes that connected Tehran to Qom. The above research was carried out with the objectives of identifying and documenting as well as understanding the formation and function of related facilities in the ancient roads located in the south of Tehran to Qom province, in which two questions are also raised: 1) the most important communication roads located in the southern part of the province What are the communication routes between Tehran and Qom? And 2) which pattern or patterns did the studied road network generally follow? Based on this and relying on historical written sources and archeological field studies, we can propose the following hypotheses: three important communication routes in the studied area, from the dimensions of road scenery [residence-welfare, security-guidance-movement scenery] which are a They were a coherent group, they obeyed. Routes that, apart from having (commercial and economic effects) Functions on the communities living in their neighborhood; they also had many effects on the (cultural and social relations) of these societies. The present research was done with descriptive-analytical method and gathering information in the form of documentary and historical studies and archeological investigations. The results of the present research indicate that three important communication networks [1) Abdul Azim Ray Gate - Kenargerd - Dier kechein - Qom, 2) Aliabad - Hoze Sultan - Qom (abandoned) and 3) Aliabad - Manzariyeh - Qom] in the southern region of Tehran province. It was located towards Qom in chronological order.

Introduction
Regarding the description and recognition of the ancient and communication routes from the south of Tehran province to Qom in the Islamic era, at the beginning with the center (Rey) and later (Tehran), there have been several historical and geographical documents that show that the communication routes The above in this area were of great importance for the governments of this period. Ibn Faqih, describing the main roads of Ray to the neighboring areas in terms of commercial nature, says: Goods were also produced by Ray artisans, they made crafts such as combs and salt pans, etc. from wood. Ray weavers were also famous worldwide and all kinds of They exported clothes to the eastern and western regions through the important roads of this city) (Ibn Faqih, 2000, 51). Moghdisi also writes about the roads of Ray from a (mobility-security) point of view: ((the easiest and most prosperous road in Iran is the road of Ray)) (Moghdisi, 1982: 718) and further says: it is clear that this feeling Comfort and security should be established for travelers so that they can easily take advantage of all the sights and facilities provided near the road (ibid., 574). Ibn Hawqal also paid attention to the Ray road from the (commercial nature) and in this context he says: Apart from Isfahan, which was a commercial and important city, from Iraq to Khorasan (Ray) can be mentioned, which is The reason for having different main and secondary ways in terms of production and export of goods is unique and significant (Ibn Hoqal, 1987: 106). Bakran considers the distance between Ray and Isfahan to be about 62 farsang (Bakran, 1963: 15) and Imam Shushtari, like Bakran, considers the distance between Ray and Isfahan to be 62 farsang (Imam Shoshtari, 1960: 35). Mostofi states that the distance between Ray and Isfahan is 86 farsang (Mostofi, 1983: 51). In the last few decades, our understanding of the above-mentioned communication routes relied more on the same historical documents. However, due to the abundance of archaeological evidence related to these routes, which included buildings and facilities related to them; In previous years, they have been studied and investigated by some researchers and archaeologists in the field, and these archeological evidences themselves support the first hypothesis in line with their alignment with the writings of historical-geographical texts and travelogues in the best possible recognition of communication routes. It illuminates between the two cities of Tehran and Qom.

Discussion
The southern region of Tehran province was considered as one of the key strategic and geographical regions during the late Islamic centuries. The existence of numerous buildings and intermediate structures in the three ancient routes of Tehran - Qom, shows the archaeological evidence and the importance of this region. As mentioned, this highway starts its route from the south of Tehran province and passing through the cities and villages located in this area to the city of Qom and from there, turning into several branches to other parts of the country such as Isfahan, Kashan, Arak and others. The southern regions are connected. One of the most important features of this highway is its (cultural and religious) dimension. The cultural and religious dimension of this course can be seen as the first option that was always considered by the rulers of the late Islamic centuries, especially Safavieh and Qajar. The reason for this importance was the existence of the holy court of Hazrat Masoumeh in the city of Qom. Therefore, this issue caused the rulers of the later Islamic centuries to build and erect numerous buildings and facilities on the way to the extent possible for the well-being of these pilgrims and caravans, and many of these buildings are still standing. Another importance of Tehran-Qom highway; It was connected with the Tehran-Khorasan highway, which along with this highway was also considered one of the cultural routes and thresholds of Iran’s nobility. The third strategic importance of the Tehran-Qom highway is the ((commercial)) dimension in the way that in the late Islamic centuries, this highway was a very important bridge for the exchange of commercial and commercial goods that went to Tehran and the north of the country through Bushehr port. were carried One of the other important issues that always add to the importance of the Tehran-Qom highway was the (political and military) dimensions, because the statesmen of the late Islamic centuries [Safavieh and Qajar] to advance their goals in these fields and reach the capital as quickly as possible. As well as the open waters through the Persian Gulf and the Oman Sea and on the other side of the Caspian Sea, they urgently needed a good route to achieve these goals, which has high levels of amenities and road-dependent facilities. Therefore, the existence of these mentioned dimensions has proved the special importance of the southern region of Tehran province.

Conclusion
Based on the questions and assumptions raised, as well as citing historical sources, archeological investigations and the analysis of these components together, we can reach the conclusion that the southern region of Tehran province due to its special cultural and political position that during the last centuries Islam has always been important from the rulers of this era, and on the other hand, categories such as trade brought the transfer of cultural and social experiences to the people living along these communication networks, and these communities themselves are somehow a part of this economic cycle. and were considered cultural. Therefore, the existence of these three important communication routes: 1) Abdul Azim Ray Gate - Kenargerd - Dier kechein - Qom 2) Aliabad - Hoze Sultan - Qom [abandoned] and 3) Aliabad - Manzariyeh - Qom, which also followed the patterns of Manzariyeh Road. The importance of this area is increasing. so, from the archaeological evidence that included buildings and intermediate structures [caravans and bridges], he also acknowledged that the studied routes were always the place of traffic and passage of many commercial caravans and travelers. However, several reasons can be imagined in the field of recognition, formation and functioning of these communication ways and the buildings and structures located in them: 1) the history and long history of the territory of southern Tehran province in the creation of roads and facilities related to them. 2) Two factors of preparation of main roads and provision of comfort facilities and safety of travelers and caravans ((road monitors)) which were realized by completing road construction and construction of intermediate buildings: a) establishment of caravanserais and shelters. b) Creating water structures and solving problems of lack of water in these routes (reservoirs and glaciers). c) Establishing security and guarding caravans and passengers. 3) The religious and political competitions of the governments of this period [Safavieh] with other governments [Osmani] in order to encourage the people of Iran to visit the shrines. 4) The military and administrative dimension and the political competition of the Western governments such as Russia and England were taking steps to dominate the roads of this region in the advancement of their colonial interests. In the end, what can be said about these ancient ways: that they are the same communication networks of today that have continued to exist with little changes.

Abstract
Identity is one of the concepts that has a wide meaning in humanities. In recent years, ‎the issue of identity has become more important in the face of globalization. ‎Therefore, the identity of cultural-historical rilcs with different concepts has been ‎the subject of many international documents, including the Scientific and Cultural ‎Educational Organization of the United Nations, UNESCO and the International ‎Council of Monuments and Sites, ICOMOS. How the concept of identity has been ‎considered in international documents related to cultural heritage, such as UNESCO ‎and ICOMOS, is a question that this research addresses. Based on this, in the current ‎research, the characteristics and dimensions of the concept of identity in these ‎documents were examined and related concepts were extracted and analyzed. For ‎this purpose, the identity contained in the mentioned documents was examined from ‎the framework of social sciences. Studies related to social sciences have been used ‎interpretatively and content analysis method to examine international documents. In ‎the content analysis, after a detailed study of the texts, key phrases and codes were ‎extracted and classified into three main categories and ten subcategories. The main ‎categories include identity, identity characteristics and identity dimensions. By ‎analyzing the obtained results, a model for investigating the identity of a cultural-‎historical relic was explained. According to this model, the identity type of the ‎cultural-historical relics is one of the seven types of identity, which includes three ‎one-dimensional types, three two-dimensional types, and one three-dimensional ‎type. This model is useful in understanding the dimensions and identity aspects of ‎cultural-historical rilcs. The importance of this model lies in the ‎comprehensiveness of knowledge that is obtained in relation to cultural-historical ‎relices, because the comprehensiveness of knowledge of cultural-historical relics ‎makes it possible to take the most appropriate way to face them.

Introduction
In the contemporary century, with the emergence of the new trend of globalization, the main values ‎related to cultural heritage faced emerging social and economic facts as well as sustainable environmental ‎development. On the other hand, industrial developments were another factor that affected the ‎disappearance of many cultures and even previous industries. For this reason, along with the growth of ‎modern industrial society and globalization, sacred landscapes and sites are facing the danger of ‎extinction. So that after the ‎‏19‏th century, we have witnessed the complete decline of some cultures, which ‎have buried with them the knowledge of the location and meaning of the sacred sites and have erased ‎them from our minds. However, there are many areas that still preserve their traditions.  Accordingly, the ‎issue of cultural identity has become one of the central issues in modern cultural policies and has become ‎the subject of many international documents in different ways. Therefore, the purpose of this research is: ‎‎”to explain how the concept of identity in cultural-historical relics is based on UNESCO and ICOMOS ‎documents‏”‏
In relation to how to deal with a relic, many documents have been compiled in recent years that have ‎tried to help the protection of historical relics. Here there are questions related to the concept of identity, ‎which are: How is the identity of cultural-historical relics explained in UNESCO and ICOMOS ‎documents? How can the intrinsic and credit dimension of the identity of cultural-historical relics in the ‎documents of UNESCO and ICOMOS be explained? The present research qualitatively answers the ‎questions raised by relying on induction in ICOMUS and UNESCO documents. The content analysis ‎method was used to study the documents. First, the main sentences related to the aforementioned study ‎axes were selected and then the key sentences were extracted from the main sentences. In the next step, ‎key sentences were coded. These codes were determined based on the concepts in the sentences. In the ‎next step, the extracted codes were placed under subcategories and in the final step, the subcategories were ‎classified under the main categories. ‎
In this research, the statistical population includes ‎‏15‏‎ documents related to UNESCO and ICOMOS, ‎which include regulations, recommendations and international charters from ‎‏1956‏‎ to ‎‏2005

Identified Traces 
Based on content analysis in UNESCO and ICOMOS documents, three main categories have ‎been formed under the title of identity, characteristics of identity, dimensions of identity‏. ‏
‏That is, in these documents, attention has been paid to the concept of identity in the ‎subcategories of cultural diversity, diversity of values and assets. In fact, in the documents, the ‎concepts related to the identity characteristics of the cultural-historical relics were extracted, which includes the ‎subset of aesthetic, cultural, social and special characteristics‏. ‏
A number of extracted codes were placed in the main categories of identity dimensions based ‎on the topic and content. These codes were classified in the subsets of intrinsic dimension, ‎primary credit dimension and secondary credit dimension‏. ‏
It can be said that the identity of the cultural-historical relics is based on having different dimensions, and the ‎difference in their identity is due to the difference in their dimensions. Therefore, some cultural-historical relics ‎are one-dimensional, some are two-dimensional, and some are three-dimensional. In fact, the ‎effect is the result of the performance of these dimensions‏. ‏
Based on the said identity dimensions, it is possible to explain a model based on limit cases for ‎a cultural-historical relic. The importance of these limit states is that it makes it easy to ‎understand the identity dimensions of the relics and avoids identifying some identity ‎dimensions. It also guides us to know which part of the identity of the relic is damaged. As a ‎result, it contributes to the pre-studies of conservation and restoration and causes them to be ‎pathological, as a result, identity measures are carried out in such a way as to avoid the identity ‎crisis of the cultural-historical relic. ‎ 

Conclusion 
In cultural-historical relics, the mentioned dimensions in interaction with each other form the ‎identity of the relic. Interaction in identity in one-dimensional relics is formed among the ‎characteristics of the same dimension, and in relics with two-dimensional and three-‎dimensional identity, the interaction between the characteristics of each dimension is formed ‎with other dimensions. In two-dimensional and three-dimensional cases, it is formed with an ‎intermediate space between its different dimensions. In this space, the identity dimensions of ‎the relic interact with each other to create a common space. This space is actually an ‎intermediate space that is formed between different dimensions of the relic, which is different ‎in each relic according to its unique position. The identity dimensions of the relic interact with ‎each other at the point of intersection, and this makes each relic express its identity according ‎to which one of the dimensions is closer. Identity development is not the result of a single ‎aspect. Rather, it is a formative thing based on the dialogue of different aspects of the relic. ‎This means that all aspects of the relic are in a mutual relationship and none of these aspects ‎alone can form the identity of the historical-cultural relic.‎

Abstract
Historic cities, as reflections of the interaction between natural and human forces over different periods, have always provided a basis for studying physical structures and spatial transformations. From this perspective, the historic city of Narāq—due to its particular geographical location along the communication routes from Kashan to western Iran and its access to natural resources and physical elements—has so far remained largely unexamined. The main objective of this study is to investigate and analyze the role of both natural and human geographical factors in the formation of the spatial structure and the physical transformations of Narāq throughout its history, an issue that has not yet been addressed in a comprehensive and systematic manner.   This study employs a descriptive–historical approach, utilizing both documentary and field data collection methods. Historical written sources—including geographical texts, travelogues, waqf deeds, and local documents—were analyzed.  The findings indicate that Narāq’s location along major historical trade routes and its access to water resources, combined with the region’s specific topographical conditions, played a pivotal role in its economic prosperity and in shaping the city’s linear spatial pattern during the Safavid and Qajar periods.  The findings indicate that Narāq’s location along major historical trade routes and its access to water resources, combined with the region’s specific topographical conditions, played a pivotal role in its economic prosperity and in shaping the city’s linear spatial pattern during the Safavid and Qajar periods. The interruption of these communication routes and the economic changes in the contemporary era have led to a decline in the city’s urban functions, creating a spatial disconnect between the historic core and the new urban developments. The research highlights the need to formulate conservation strategies and spatial regeneration plans that aim to restore the relationship between the historic elements and the city’s contemporary structure.
Keywords: Narāq, Historical Geography, Communication Routes, Spatial Structure, Historic City.

Introduction
Previous studies on the city of Narāq have primarily provided a brief examination of its physical fabric and individual historical monuments, without offering a systematic understanding of the role and impact of natural and human geographical factors in the city’s spatial and physical formation and transformation. Moreover, the alteration of communication routes in the contemporary period and the resulting disruption in the continuity of physical and functional connections have posed serious challenges to the city’s historical identity and spatial cohesion.
The central question of this research is how natural factors—such as climate, water resources, and topography—and human factors—including economic, cultural, and political relations—have, at different historical periods and in various ways, contributed to shaping the spatial and physical structure of Narāq, and what consequences this process has had for the pattern of the city’s contemporary development.
The study and analysis of the historical geography of ancient cities—particularly Narāq—is significant because these settlements represent a living reflection of the interactions between natural and human forces throughout history. Understanding the processes that shaped them provides a valuable basis for interpreting their spatial and historical identity, for planning sustainable development, and for formulating policies aimed at conserving urban heritage.
At a time when many of the country’s historic cities are facing crises of identity and physical integrity as a result of contemporary spatial and functional transformations, examining the factors that influenced the spatial formation and evolution of Narāq—as a prominent example of a strategically located settlement on the Iranian Plateau—can help identify development patterns that are better suited to local and historical contexts.
The necessity of this research also lies in filling the existing gap in systematic historical–geographical studies on Narāq and in clarifying the role of communication routes and natural resources in its spatial formation and subsequent transformations—an issue that has been largely overlooked in both national and regional research so far.

Research Questions and Hypothesis: The primary research question aims to identify the key factors that influenced the historical development of the city of Narāq. In particular:
• What role have human factors played in the city’s formation?
The primary hypothesis proposed in response to these questions relates to Narāq’s distinctive geographical position—specifically, its location along major communication routes. Although environmental factors such as water resources and agricultural lands played a crucial role in the formation and subsequent transformation of the city’s spatial structure, these developments were fundamentally shaped by regional connections and the city’s position on important trade routes.

Urban Structure of Narāq
The principal structural elements of a traditional Iranian city typically include: the Arg or Kuhandezh (citadel), the Shahrestan (main residential city), the central urban complex—comprising mosques, madrasas, bazaars, and neighborhood centers—urban connecting spaces such as alleys (guzar), squares, hosseiniyehs, and shrines, the outer section (rabad) with surrounding villages, gardens and farmlands, as well as water-related features such as qanats, cisterns, and icehouses (Tousili, 2012: 34).
Field surveys show that among these elements, Narāq essentially lacks a Kuhandezh (old citadel) that would have formed the basis for the city’s secondary development. This absence may be attributed to the history and type of early settlements in the region, characterized by numerous farmlands scattered across the geographical setting of Narāq. Kalantar Zarrabi, in his History of Kashan, describes it as follows:
“From Narāq, a great river and torrent descend from the mouth of Suk Cham, first from the southern and western highlands of Kashan, crossing the travelers’ road to Iraq-e Ajam and Arabia, and finally reaching the Kashan plain. Along the banks and surroundings of the river lie green and flourishing villages and farmlands.” (Kalantar Zarrabi, 1962: 17)
From a morphological perspective, Narāq exhibits a compact urban fabric oriented east–west, following the course of the river and parallel to the northern and southern mountain ranges. This layout clearly reflects the influence of geographical location on the city’s form. The urban fabric is shaped by two main thoroughfares:
• Imam Khomeini Street, which extends in an east–west direction, and
• Fazel Naraqi Street, which runs parallel to Imam Khomeini Street, starting from the eastern part of the city and leading westward to the Jame’ Mosque.

Conclusion
This study aimed to explore the historical geography of the city of Narāq and to explain the role of natural factors in shaping the city’s formation and spatial–physical transformations. The findings reveal that Narāq’s distinctive geographical location along the historical communication routes between Kashan and western Iran—especially during the Safavid and Qajar periods—provided an effective foundation for spatial development, economic prosperity, and the consolidation of its urban status. Abundant water resources, the linear topography, and the close relationship with surrounding fields and gardens, together with communication corridors running parallel to the river and valley, led to the formation of the city’s unique physical structure and the establishment of functional elements such as the bazaar, squares, and religious centers along east–west axes. Chronologically, it was shown that during the pre-Islamic and Sasanian periods, settlements were primarily located in the surrounding areas and on the elevated fringes. Gradually, in the Islamic era—particularly during the Safavid period—the city’s spatial and communicational center became firmly established near the river. This spatial pattern reflected the natural setting and the functional needs of the traditional society of that time. The analysis of more recent developments indicates that the redirection of major communication routes and the consequent disruption of the city’s functional connection with its former strategic networks have resulted in economic decline, spatial disjunction within the historic fabric, and the diminishing role of the bazaar, placing the city on a path of uneven contemporary transformation. Given Narāq’s limited population and the modest pace of migration, no major transformation of the city’s structure has occurred; its historical evolution continues to be shaped largely by natural advantages and geographical factors. The research demonstrates that a thorough understanding of historical geography and the application of traditional models compatible with the natural setting and the socio-cultural context play a crucial role in preserving and enhancing the city’s historic structure, both now and in the future.

Among the most significant historical and ancient sources in Iran are local handwritten deeds and manuscripts. Through their examination and study, valuable historical information can be obtained. These documents contain detailed accounts of geographical, economic, social, cultural heritage elements, customary laws, and traditional customs. Today, they serve as valuable and primary historical resources. In this context, the province of Isfahan stands out as one of the richest regions in terms of historical depth and the tradition of deed writing in Iran’s local and traditional history. Notably, the handwritten deeds related to the Gourt neighborhood in eastern Isfahan (Eastern Jay) have not yet been studied from historical, archaeological, or codicological perspectives. This research aims to present the writing style, structure, and valuable historical content of these documents, introduce them by their original and traditional names, and highlight their importance as precise historical and archaeological sources. It also seeks to showcase the artistic features used in their illustration and decoration as part of the region’s art history. The central question of this study is: How can we extract historical and artistic information from handwritten deeds and evaluate them as credible historical sources? To achieve this goal, three historical manuscripts from the Gourt neighborhood in eastern Isfahan have been scientifically and analytically examined: Deed of the Dove Tower at Darb Deh (Aziz Tower), Deed of the Dove Tower of Agha Hossein, (New Tower) Deed of the Gourt Farm Qanat. These manuscripts belong to a private local collection, preserved as family heritage, and have all been registered as movable historical artifacts by the Cultural Heritage Organization of Isfahan.

Abstract
Material remains bearing figurative representations constitute one of the most significant repositories of historical-cultural information within archaeology and art history. Among such remains, artefacts depicting the cheetah are of particular importance. The interpretation of surviving cheetah imagery in ancient artefacts undoubtedly yields a deeper understanding of coexistence and confrontation between human societies and this predatory animal. Archaeological findings and iconographic analyses conducted thus far on the cheetah indicate that variables such as geographical distribution, temporal multiplicity, and the frequency of cultural interactions have played a considerable role in explaining the transformation of cheetah motifs across different historical periods. Accordingly, after examining the history of studies on the cheetah, as well as investigating the developmental trajectory of cheetah images among coeval cultural horizons in Iran—which have predominantly confined the origin of cheetah motifs from prehistoric times to the late Islamic period to two interpretive models, namely the narrative-mythological and the ritual-ideological—the present study seeks to examine visual examples of the cheetah, while emphasizing the role of predatory hunting animals in human societies, and furthermore to highlight the importance of the functionalist-subsistence interpretive model. This model is grounded in historical texts, specifically hunting manuals, as one of the fundamental causes for the representation of cheetah images, in contrast to the two aforementioned models. For this purpose, archaeological evidence together with comparative studies of historical texts, through an analytical-comparative method, have been re-examined to demonstrate that functionalist interpretations concerning the capture and domestication of this predatory animal by cheetah-keepers in the natural world are of equal or even greater importance than prevalent mythological and ideological interpretations, which are exclusively concerned with political authority and ritual legitimation within the cultural sphere.

Introduction
Material remains featuring cheetah depictions are vital sources for understanding the coexistence of human societies and this predator. Previous iconographic analyses suggest that geographical distribution, temporal shifts, and cultural interactions have shaped the evolution of cheetah motifs across rock reliefs, seals, and pottery. While researchers typically attribute these stylistic transformations to decorative, mythological, or ritual concepts, this study proposes a “functionalist -economic” interpretive model as a fundamental driver for these representations.
Tracing cheetah imagery from prehistory to the late Islamic period through archaeological evidence and historical texts—such as hunting treatises (šikār-nāmes) and training manuals (bāz-nāmes) like the Bazname-ye Nasavi—this research challenges purely symbolic readings. The central hypothesis is that the domestication and control of the wild cheetah in Iran were primarily pragmatic processes tied to survival. Ancient humans first harnessed the animal’s hunting abilities to secure food and mitigate risks in the open landscapes of the Iranian plateau, only later embodying these functional roles in mythical and ideological discourses.
By employing an analytical-comparative method across field data from various Iranian regions and reliable library sources, the findings indicate that functionalist interpretations (related to capture and taming) hold equal or greater significance than purely ideological motifs of political authority. Ultimately, this research emphasizes that cheetah representations in ancient Iranian artifacts reflect humanity’s core subsistence concerns and evolutionary adaptation. The functionalist model of human-cheetah coexistence is a long-standing reality that should not be overlooked in favor of purely symbolic or mythical interpretations.

Discussion
This article examines the representation of the cheetah in two principal categories of historical written sources: literary texts (hunting poetry and travel narratives) and technical manuals (bāznāmas/šikārnāmas). Findings indicate that in literary sources, the cheetah is predominantly depicted with attributes such as speed, agility, and ceremonial status within the royal court. Poetic examples from Ferdowsi (“one hundred and sixty cheetah handlers”) and Gorgani (“you think we are the deer and he is the cheetah”) suggest that the cheetah served not only as a hunting companion but also as a symbol of royal authority over nature. Travel accounts, such as Chardin’s, provide tangible details regarding the practice of carrying the cheetah on horseback and removing its blindfold at the moment of the hunt.
The analytical turning point, however, lies in the examination of technical manuals, particularly the Bāznāma-ye Nasavi. This monumental work constitutes the most comprehensive historical document concerning the capture, domestication, and training of cheetahs. Nasavi details a seven-stage process: digging pits for live capture, transferring the animal to royal facilities, sleep and food deprivation, training on a “clay donkey,” mounting a horse, entering the hunting ground, and ultimately achieving hunting success.
The principal contribution of this article resides in its systematic correlation of these technical texts with six visual specimens. The Jiroft image (Fig. 12), depicting a human holding a cheetah’s tail, corresponds precisely with the role of the “tail-holder” (domdār) described in the Bāznāma-ye Nasavi. The Sanandaj Museum bowl (Fig. 13), showing a cheetah springing onto the back of a clay bull, directly represents the “clay donkey” training stage. The Samanid-era vessel (Fig. 14), portraying a cheetah seated on a horse, aligns perfectly with descriptions found in hunting manuals.
In conclusion, this article demonstrates that a functionalist-biological reading of cheetah imagery—grounded in written evidence from bāznāmas—possesses equal validity and fundamentality to mythic and ideological interpretations, and may, in certain historical contexts, constitute the very foundational basis for these representations.

Conclusion
The history of studies and interpretations of the visual evolution of the cheetah indicates that cheetah motifs from the fourth millennium BCE to the Islamic period developed gradually, moving from a “decorative singular depiction” toward “mythological-ritual narrations” and finally to “political-ideological symbols.” As demonstrated, most of these studies have predominantly considered the mythological-ritual and political-ideological approaches as the main foundations of the cheetah motif’s evolution, and within their interpretive framework, they have frequently referred to the cheetah as a symbol of power, mastery over nature, and political authority. The present study, through an examination of case studies and their correspondence with historical written documents, has shown that the factors underlying the visual representation of the cheetah, in addition to the above interpretive models, are primarily based on functionalist-biological interpretations, in which the predatory animal was utilized by ancient humans for the purpose of fulfilling their subsistence and biological needs, aiding and facilitating the hunting process, and thus constitutes one of the most important factors in the visual representation of the cheetah.
Accordingly, since the simultaneous re-examination of archaeological evidence and technical-historical texts such as the Bazname-ye Nasavi demonstrates that the stages of capture, domestication, and training of the cheetah for hunting are rooted more in subsistence necessities and human survival than in mythological or ideological representational models, the functionalist-subsistence interpretive model is not only equivalent to the two narrative-mythological and ritual-ideological models, but also temporally and causally precedes them. In other words, before humans embodied the cheetah as a manifestation of supernatural power or political legitimacy, they had mastered it as a “hunting assistant” and employed it in their encounter with the natural world. This very mastery and essential coexistence between humans and cheetahs provided the necessary material and behavioral foundation for the formation of subsequent symbolic layers. Therefore, reducing the evolution of cheetah imagery to two interpretive models—mythological and ideological—without considering its biological-subsistence context is a limited and highly reductive reading.

Abstract
Historical-archaeological sites are the most important sources to answer the missing links of a nation’s history and civilization. These areas always have diverse values, which identification and understanding of these values provides the basis for recognizing their protectable aspects. Today, most of these sites in Iran are in vulnerable conditions and their values are being forgotten. The historical-archaeological site of Arjan is located in the Khuzestan plain, which existed from the Elamite era to the Mongol era. Today, this area is in unfavorable conservation conditions. Considering the values and historical importance of the old city of Arjan in the historical periods of Iran, it is very important to protect this area and create a suitable platform to benefit from its values. Among the questions that are answered in this research;1. What are the values of Arjan historical site? 2. What are the challenges of protecting Arjan’s site? 3. How can we achieve conservation principles for the protection and valuation of the historical archaeological site of Arjan in accordance with its values? Accordingly, the objectives of the research؛ 1. Understanding the Arjan site and its conservation challenges; 2. Achieving conservation principles through the analysis of international charters, declarations, conventions and documents and generalizing them to a study sample in order to explain the principles of conservation and value it. The general research method of this research is descriptive-analytical, based on the data collected through library resources and field observations. Then, after analyzing and reviewing international documents and recognizing the historical site of Arjan and its conservation challenges in four fields of cognitive, managerial, legal, physical, and introduction and valuation of the site, principles such as providing information to the public, developing a comprehensive interaction plan, developing public management plans, reversibility of actions, preserving originality and respect for historical and aesthetic values and the physical integrity of the sites are presented.
Keywords: Arjan, Historical-Archaeological Site, Conservation, Historical Values, Introduction of Values.

Introduction
Historical-archaeological sites are the most important sources to answer the missing links of a nation’s history and civilization. These sites will answer many general and partial questions that can be varied and variable over time, so the conservation of the sites is essential for transfer to future generations. Historical archaeological sites have a variety of values and in order to benefit from these values, they are always protected. After archaeological excavations in Iran, these sites are often in vulnerable conditions and are exposed to forgetting their values.
The archaeological site of Arjan is located in the plain of Khuzestan. Arjan is a city with various urban organs in the historical periods of Iran. This site has values, features and elements that are unique in its kind. In 1362, a tomb belonging to Kidin Hotran, one of the Elamite kings, was discovered. Afterwards, Esmaeil Yaghmaei carried out archaeological excavations and studies in the Arjan area and in the area of Maroon Dam and Arjan Grand Mosque and Dr. Abbas Moghaddam conducted archaeological excavations in the area of the oil well during two seasons. With the cessation of excavations in this site, the old city of Arjan, like most historical sites in Iran, was placed in undesirable conditions of conservation.
Research Necessity: The city of Arjan has been standing from the Elamite era to the Mongol era. (Today, this area, despite its historical and archaeological importance and values, is in unfavorable conservation conditions) Considering these values and the historical importance of the ancient city of Arjan in the historical periods of Iran, as well as the necessity of continuing archaeological studies and the availability of its original data among researchers and enthusiasts, it is very important to protect this site and create a suitable platform for benefiting from its values.
Research objectives: 1. Understanding the Arjan site and its conservation challenges; 2. Achieving conservation principles through the analysis of charters, statements, conventions and international documents and generalizing them to a study sample in order to explain the principles of conservation and valuation of the archaeological site of Arjan.
Research Questions: 1. What are the values of Arjan historical site? 2. What are the challenges of protecting Arjan’s site? 3. How can we achieve conservation principles for the protection and valuation of the historical archaeological site of Arjan in accordance with its values?
Research Methodology: The general research method is descriptive-analytical approach. In this research, library studies and field studies have been utilized to gather information.

Discussion
“Archaeological heritage” is a material heritage that includes all traces of human life and includes places that show human activities, abandoned structures, and remnants, along with all the movable cultural objects discovered related to it (ICOMOS, 1990). These sites have a variety of values and in order to benefit from these values, they are always conserved. By reviewing the international documents related to the sites in Table 3, the set of conservation principles in four areas, cognitive, legal and managerial, physical, and the introduction and valuation of the site, has been displayed.
The archaeological site of Arjan with an area of 500 hectares is located on the slopes of Khoiz Mountain and in a wide plain next to the Maroon River, which includes the Mosque Jammeh, the Arjan Dam Bath and Bridge, the Qadamgah of Imam Reza (AS), the Rosh Mehr Building, the Arjan Qanats and the ancient hills. By examining the site and the buildings in it, the values are divided into two categories, cultural values and contemporary economic and social values (Diagram 5). At present, the buildings in the Arjan site are in an undesirable state of conservation and their values are in danger of being forgotten. Through field surveys, the damages and challenges of the Arjan site were identified in four areas, cognitive, legal and managerial, physical and tourism, and were divided into two groups, internal and external factors. Internal factors include cognitive domain, exhaustion (functional physical) and weakness in the infrastructure of the Arjan site, and external factors include lack of alignment of organizations and weakness in the managerial and legal structure. According to the mentioned damages and challenges, by identifying their roots and categorizing them in the form of internal and external factors, we have achieved five conservation challenges related to the historical archaeological site of Arjan (Diagram 4). By adapting the principles of conservation of historical sites to conservation challenges, the principles of conservation of the Arjan site are stated in Table 4.

Conclusion
Historical archaeological sites can be considered as the most important sources for answering the missing links of a nation’s history and civilization. These sites always have a variety of values, and identifying and understanding these values can provide the ground for recognizing their protectable aspects. In the twentieth century (in 1914 and 1916), the main law for the protection of historical sites was adopted, and at that time, terms for the protection of historical sites were created in international charters. In the first part of this research, international charters, documents and conventions were examined in terms of keywords related to historical archaeological sites and the conservation principles related to the sites were identified in 4 areas. In the second part, in relation to the study area, with the knowledge of the old city of Arjan and with an analytical view of field studies, through the analysis, investigation and categorization of the challenges of conserving the historical archaeological site of Arjan and the comparison of the challenges with the principles extracted from international charters, documents and conventions, led to the explanation of the principles of the conservation of the historical archaeological site of Arjan.
The principles of conservation of the Arjan site were presented in four areas: cognitive, managerial, legal, physical, and introduction and valuation of the site. One of the most important principles in the field of cognition was to provide information to the people and to develop a comprehensive interaction plan. Formulation of public management programs, coordination and cooperation between institutions and people, and formulation of intervention laws are among the most important principles in the field of management and law. In the physical field, the reversibility of actions, preservation of originality, continuity of vernacular architecture and native materials, and documentation of changes were mentioned. Respecting the historical and aesthetic values and the physical integrity of historical buildings and sites is one of the most important principles in the field of introducing and valuing the site. It should be noted that these cases, along with other conservation principles proposed in the research, lead to the improvement of the condition of the archaeological site of Arjan.
