“Historical map of Karun river route toward Shushtar and the source of Zayandeh Rud” is among the historical map series of Khuzestan which was prepared and drawn by Abd Al-Ghaffar in Ramadan 25th, 1299AH. This map illustrates Karun River, Zardkuh Mountains, Dez river in Dezful, Kuhrang Mountain, Zayandeh Rud River as well as coal mines, farms and roads of the region. Najm Al-Mulk, the well-known engineer of Qajar era, has professionally implemented the mapping methods of those years to draw this map. In addition to Najm Al-Mulk’s services to modern engineering and topography of natural areas system of Iran and particularly of Khuzestan, the details of the map are also explained here. The title mentioned in its identity certificate which includes the main Karun River toward Shushtar and the source of Zayandeh Rud, has been chosen as the title of this research. Fortunately, it is known who has drawn this historical map; it is the late Haj Abd Al-Ghaffar Naj Al-Mulk (1839-1908AD), The engineer, historian and astronomer of Naseri era who played a significant role in preparing the geographical maps of Khuzestan. His scientific-engineering records are the indicative of his great activities in this field. Moreover, his “Khuzestan travelogue” is seen as a golden sheet of the history and geography of Khuzestan in Qajar era which can be a valuable heritage for future generations. Based on the data written on the map, it dates back to Ramadan 25th, 1299(1882AD). The name of the drawing location, Tehran, and the drawer’s, Abd Al-Ghaffar, have also been declared on the map. The year 1299AH coincides with 1260SH. Therefore, the map dates back to 136 years ago (based on solar calendar) and 141 years ago (based on lunar calendar). One of the most important traits of this map is illustrating the natural zones, the terrain as well as Karun, Dez and Zayandeh Rud rivers zones which have been shown using particular lines. The lawn and farming surroundings of Karun, Dez and Zayandeh Rud rivers in addition to the longitudinal and transverse shears of Karkonan Mountain are also reported on this map. The sentence “The scale is one part of 20000 parts” shows that the area scale is 1 to 20000 which seems really small in comparison to the river length. The map dimensions are 48×69 cm which seems mediumsized in comparison to the maps existing in the archives of Foreign Affairs Ministry. Among the series of the historical maps remained from Haj Abd Al-Ghaffar Najm Al-Mulk (Najm Al-Doleh), this map has outstanding traits such as showing natural resources including rivers, mountains, the lawn, farms and fertile lands since the ultimate goal has mostly been planning for agriculture and optimal exploitation of rivers as well as getting accurately acquainted with the region to obtain annual taxes. The historical map of “Karun toward Shushtar and the source of Zayandeh Rud” is a clear evidence of such attitude existence. Another noteworthy point is the longitudinal and transverse shears of Karkonan Mountain on such a scale which is a rare one compared to the other maps of Qajar era. This is the indicator of the late Najm Al-Mulk’s precision who was a distinguished cartographer of that era. Keywords: Karun

Seyedun or Seyedun Ali Naghia tomb is located in Nebadan district of Abarghu. This clay monument is a tall dome chamber on the exterior cover of whose dome there are bricks as well as blue and azure tiles. The interior dado is also covered by tiles and the underneath surfaces are decorated with clay Muqarnas, inscriptions and slight painting ornaments. A vast part of the dome cover crumpled probably in 1330sSH (1950s AD) and was renovated some decades later. This building is a mosque attributed to 9th century (AH) called masjid-hosseiniyeh or hosseiniyeh of Nebadan. A small part of it which is part of the attached installations has just remained. It has had an altar whose direction confirmed to the skew Qibla of the congregational mosque and masjidhosseiniyeh of Abarghu. No dated inscription or including the founder name one can be found there. Seyedun Ali Naghia has been briefly inspected in the previous references and is attributed to 8th century (AH) based on Donald Wilber and Godard’s dating while it has been attributed to 6th- 8th centuries (AH) in the national registration file. In this research we try to date the tomb through investigating related documents, its structure and also the comparative inspection conducted during the preparation period of the renovation plan. In addition, we look for the answer to the question whether it was constructed in one single era and when it was built. Its initial function is another issue to be investigated. The dado tiles order, the way of drawing and embellishing Kufic handwriting of the inscriptions and the way of creating squinches in this monument to a great extent resemble 8th century monuments of Yazd and Isfahan. Moreover, the content of the verses written on the inscriptions which alludes to the burial use of them, in addition to above-mentioned traits, arouse the strong possibility of this monument being built as a tomb and for burial purposes. Both the structure and the ornaments are very similar to the damaged tomb of Hasan Ebn-Keikhosro (with an inscription dated 707-718 AH). Since the construction date of that tomb is known, it is likely that Seyedun Ali Naghia was also built in the first quarter of 8th century; the era during which king Mobarez Al-Din could overcome Yazd and Meibod that led to the reign of Mozaffarian dynasty to start. In addition, based on its similarities to 8th century monuments like Seyedun Golsorkhi and Hasan Ebn-Keikhosro domes and through investigating Jame’ Al-kheirat endowment in which Nebadan desert of Abarghu has been mentioned, we conceive that the mentioned buildings were all made in one single era with the fund of a famous figure who might belong to Seyed Rokn Al-Din family. Through investigating the structure of Seyedun Ali Naghia no trace of two different eras was found which leads us to the strong possibility that all of them were constructed in one single era. The content of the inscriptions read in this research for the first time, are Quran-related. We can foresee that more evidences particularly of the original forms of dome covers ornaments would be obtained through future renovations which might in turn reveal other aspects of the monument history.
