Mersin Chal Cemetery; Reflection of Cultural Interactions in the Northern Central Plateau of Iran Based on Archaeological Data Analysis

The Mersin Chal Cemetery is considered one of the extensive burial sites in Iran. It’s strategically located on the corridor connecting the desert regions and the Iranian Central Plateau on one side with the northern and northeastern parts of Iran. The cemetery is situated along the southern edge of the eastern Alborz mountains. During the third season of archaeological excavations at this cemetery in 2021, 49 graves were identified and excavated. The data obtained from this season provide a valuable collection for studying burial practices and examining regional cultural dynamics from the late Iron Age III to the early Parthian period.  The aim of this research is to examine the grave goods within the context of cultural interactions, particularly through typological and comparative analyses with contemporary sites in northern and northeastern Iran. The research methodology follows a descriptive-analytical approach, utilizing data collected from both fieldwork and documentary/library research. The findings reveal that the graves at Mersin Chal exhibit a relatively consistent pattern in terms of orientation and general structure, reflecting a stable burial tradition. However, variations in the quantity and quality of grave goods suggest social differentiation within the community. Furthermore, the pottery assemblages also show notable typological similarities to sites such as Shahr-i Qumis, Tepe Kesht, Tepe Dibaj, Velem Cemetery, Vestemin Cemetery, and Shahneh Poshteh, indicating cultural connections and regional interaction.  Moreover, the discovery of a bronze seal ring, featuring an image of Heracles and a Greek inscription, holds particular historical and cultural significance. This find may point to contact with Hellenistic cultural spheres during the early Parthian period. Overall, the available evidence suggests that Mersin Chal, during the second half of the first millennium BC, was integrated into broader networks of regional exchange and cultural interaction, especially with northern and northeastern Iran.
