In the second half of the fourth millennium BC. Southwest Asia underwent social changes, the result of which was the emergence of writing. In these developments, the cuneiform script in the south of the Mesopotamia and the Proto Elamite in the Iranian plateau progressed rapidly to such an extent that at the beginning of Elamite was scattered throughout the Iranian plateau. These writing systems were used for administrative and accounting purposes, and despite the fact that most of their signs are different from each other; there are important similarities between the two. Chalcolithic era, the best period in which you can see the idea of trading's and keeping of account; for the first time in this course, tools are seen which called them Token; it seems that the tokens in a variety of forms and counting symbols refer to a specific concept. The end of this period coincides with the Proto Elamites era in the south and southwest of Iran. Domestic production in the Neolithic period gave his place to the production of a workshop in the Chalcolithic era, which causes a lot of production. In the present study, firstly, will be investigated, small clay counters and then the Proto Elamite texts. Manuscript profile

In the east of Pahanvar Ray plain, we come to a fertile area (Pishwa/Varamin plain) which has provided suitable conditions for human habitation since the formation of human settlements until today. Due to the location of this plain in the north of the central desert and the border between the two cultural domains of the northeast and the center, the environmental condition and suitable altitude, which are the main factors for the formation of permanent settlements, and the possible existence of extra-regional connections of this area with the neighboring areas, a wide survey was conducted in this area of ​​the plain. It was concluded that during this archaeological investigation, 61 ancient sites from the Sassanid era were found in the east of Varamin and south of Peshwa. It is most likely that Varamin is considered a part of Ray State and based on the available evidence, it is possible that it is the main center of Ray State as well. According to historical texts and archeological data, the state of Ray was one of the important areas of human settlement during the Sassanid period in Iran. Historical texts mention Ray in the Sassanid period, and the number of sites attributed to the Sassanid period in the geographical area of ​​Varamin has not been found until today. Despite this, based on the prominent geographical location of the Varamin region and the references of the historical texts to the Ray state, this region was probably one of the important regions of the historical period in Iran. In the present article, an attempt has been made to describe the historical geography of Ray State in the Sassanid period, while using the archaeological data of the Sassanid period of Varamin, to draw a part of the archeology and historical geography of Varamin in the Sassanid period.

Burning and cutmarks were found on some of the bones, which cutmarks might be secondary to butchery. This study is based on field, and lab studies on animals remain retrieved from these two hills (Taghiabad 1 and Taghiabad 2). Results show that sheep, goat, cattle, gazelle, equid, deer, and canine in Taghiabad 1 and sheep, cattle, gazelle, and small carnivorous in Taghiabad 2 are the most prevalent findings.
