Sialk Hills, Kashan
Approximately 4,500 years BC., a community with an interesting civilization was settled in this area and their tools were of stone and bone. There is a possibility that the former residents of this region had succumbed to their successors. Here, Elamite slabs of clay have been found, and due to the links of this community with that of the civilization of Shoosh (Susa), about 5,500 years ago, they learned to write. Thereby, several clay slabs with the most ancient Elamite script are vestiges of this area. Evidences found in the cemetery between the two hillocks are related to the fresh immigrants to the Sialk Hill, which bears a strong resemblance to the discoveries in the Giyan Hillock of Nahavand and Khordin of Savoj Bollaq.
