Abstract
During the fourth millennium BCE similar wares used to produce and use in the extended area in Near East which is so-called Beveled rim bowls. Its importance is for high quantity and similarity in production techniques. Different studies on dating, function, and the main reason for the spread of this pottery style have been done. Although beveled rim bowls were found in many sites in west, south, south-eastern, and central plateau, hereby new finding from Kale Kub seems that this pottery style was spread in the more extended area than what we expect. Kale Kub is located in the eastern part of Iran, Southern Khorasan, and Sarayan county. In 2018, two trenches were opened in order to identify the stratigraphy of the high amount of beveled rim bowls in addition to other pottery styles belong to fourth millennium BCE which are already known in southwestern Iran. The current study would be clarifying the importance of the Kale Kub site for identifying the dispersal zone of Beveled rim bowl pottery style by an endeavor firstly foe the classification and typology of the potteries and then a comparison between the pottery style in this site with other sites related to this period. Also, we attempt to trace the possible routes for this pottery style to the East and the interaction between east and west of Iran. Pottery collection from the excavation in Kale Kub includes a high amount of beveled rim bowls, Banesh tray, and some other pottery styles which are well-known from fourth millennium BCE such as nose handle and spouted wares. Beveled rim bowls are over 15 percent of the pottery collection and other styles have a few quantities in the collection. In term of production techniques and style, Kale Kub finds are similar to those from southwest of Iran.

Introduction
The first season of excavation at Kale Kub aimed to identify the stratigraphy sequence of this site, which has revealed the chronological sequence from fifth to late fourth millennium BCE. Cultivation and human activities in recent years resulted in disturbance in most parts of the site. Beveled rim bowls, Banesh tray, and other diagnostic pottery styles of fourth millennium BCE are the most important finds in this site. In addition to beveled rim bowls and Banesh tray, other diagnostic styles such as nose handle, spouted wares were found in Kale Kub that shows all styles belong to this millennium would have seen in the eastern part of the Iranian plateau. In modern Iran, these pottery styles are reported from the southwest, central Zagros, central plateau, and southeast, but from east and northeast just reported from Farhad Gerd which scholars believe that the reported pottery is not beveled rim bowl. Excavation in Kale Kub shows the extension of this culture to the east part of Iran. This site is located far from the well-known sites from this period in the west part of Iran and there are two deserts, Dasht-e Kavir and Lut desert, between this site and other known sites with similar pottery style increase the importance of finding the answer for this question that how this culture found its way to the east.

Conclusion
Inter-regional interactions had a significant effect on the movement of raw material and production in the extended area. Because of the geographical situation of Kale Kub at the east of Iran and the existence of metal mine in the region, this site possibly appeared as a supplier place in the interaction networks for the southwest of Iran during the fourth millennium BCE. The pottery culture which is prevalent in the southwest in this site shows clearly these interactions. To answer the question of how they were connected, we need more excavations and more information. The nearest sites with similar cultural features to the Kale Kub are Tepe Sofalin in Pishva, Varamin in central plateau; and in the southeast of Iran, Mahtout Abad in Jiroft, that both have about thousand kilometers are away from Kale Kub. This distance shows that there are highly probable some other sites between Sofalin and Kale Kub and also Mahtout Abad and Kale Kub that have not been identified yet. These two-direction routes (first, the southern boundary of Alborz mountain and north of Dasht-e Kavir; second, the southern part of Lut desert to the Sistan region and eastern parts of Iran), are the possible routes that connect the east to the fourth millennium BCE cultures of southwest in purpose of achieving the raw material. In the highlands around Kale Kub, copper mining evidence showing that these mines were used till late Islamic periods in the region as well. Also, this region has various types of opal. Kale Kub location between Afghanistan and inner part of Iranian plateau suggests that this site was formed on the way of lapis-lazuli movement routs from Afghanistan; also, the mines of turquoise at the Neishabur is near to the site. Although, finding the role of this site in the networks of fourth millennium BCE needs more information that will be revealed by more excavations but current evidence shows that this site had an exchange and production function in the trade in this period. It suggests that beveled rim bowls and other material culture from fourth millennium BCE (about 3600-3500 BCE) extended to the east from the central plateau and southern part of Alborz Mountain as well as northern side of Dasht-e Kavir.

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.
