Considerations Regarding the Fire Temples Attributed to Mehr-Narseh in the Southwest of Fars: An Indicator to Identify Dādgāh Fire Temples

Mehr-Narseh is known as one of the most important character of the middle Sassanid era. Based on the written historical sources, the construction of some buildings has been attributed to him, among which the most outstanding ones are five fire-temple monuments built in the southwest of Fars. Although various theories have been put forward regarding the location of the structures, by far, the nature and qualitative value of them are unknown. In this study firstly, the political-religious personality of this Sassanid minister in various ways was investigated, then besides recognizing their religious nature and value via analysis of the sources related to Mehr-Narseh fire temples, the Chahar-Taqis attributed to him was also studied, according to the current theories,  so as to reveal some features of  the religious architecture of Sassanid era. This is a fundamental or basic research, and the nature and method of which is historical and descriptive-analytical. The data is also collected from library and fieldwork. Based on the results of this study, it seems that the fire temples built by Mehr-Narseh included two separate types and four fire temples attriuted to him located in Abruwān area were related to family fire meaned “Dādgāh”. According to the field studies and similarity, the previous theories can be criticized and a new group of religious temple of Sasanian period in Farashband can be introduced that contains one or several fire temples, which are attributed to Mehr-Narseh. It seems that these kinds of fire temples have a complex plan with additional architectural and probably had a number of attendants to do the work related to the fire temple. Overall, this research can provide a correct understanding of the fire temples of “Dādgāh” Fire during the Sassanid period. This also provides a new grouping manner for such these temples and can be known as a pattern for reviewing of usage and religious value of other similar Chahar-Taqis.
