The Proto-Elamite period is the time of ca. 3200 BC to 2700 BC when Susa, the later capital of the Elamites, began to receive influence from the cultures of the Iranian plateau. In archaeological terms this corresponds to the late Banesh period. This civilization is recognized as the oldest in Iran and was largely contemporary with its neighbour, Sumerian civilization, the oldest in the world, which began around 3400 BC.
During the period 8000–3700 BC, the Fertile Crescent witnessed the spread of small settlements supported by agricultural surplus. Geometric tokens emerged to be used to manage stewardship of this surplus. The earliest tokens now known are those from two sites in the Zagros region of Iran: Tepe Asiab and Ganj-i-Dareh Tepe.
The Mesopotamian civilization emerged during the period 3700–2900 BC amid the development of technological innovations such as the plough, sailing boats and copper metal working. Clay tablets with pictographic characters appeared in this period to record commercial transactions performed by the temples.
Besides Susa, one important Proto-Elamite site is Teppe Sialk, where the only remaining Proto-Elamite ziggurat is still seen. Texts in the undeciphered Proto-Elamite script found in Susa are dated to this period. It is thought that the Proto-Elamites were in fact Elamites (Elamite speakers), because of the many cultural similarities (for example, the building of ziggurats), and because no large-scale migration to this area seems to have occurred between the Proto-Elamite period and the later Elamites. But because their script is yet to be deciphered, this theory remains uncertain.
Some anthropologists, such as John Alden, maintain that Proto-Elamite influence grew rapidly at the end of the 4th millennium BC and declined equally rapidly with the establishment of maritime trade in the Persian Gulf several centuries later.
Proto-Elamite pottery dating back to the last half of the 5th millennium BC has been found in Sialk, where Proto-Elamite writing, the first form of writing in Iran, has been found on tablets of this date. The first cylinder seals come from the Proto-Elamite period, as well.
Proto-Elamite script 
It is uncertain whether the Proto-Elamite script may be considered the direct predecessor of Linear Elamite. Both scripts remain largely undeciphered, and it is mere speculation to postulate a relationship between the two.
A few Proto-Elamite signs seem either to be loans from the slightly older proto-cuneiform (Late Uruk) tablets of Mesopotamia, or perhaps more likely, to share a common origin. Whereas proto-cuneiform is written in visual hierarchies, Proto-Elamite is written in an in-line style: numerical signs follow the objects they count; some non-numerical signs are 'images' of the objects they represent, although the majority are entirely abstract.
Proto-Elamite was used for a brief period around 3000 BC , or Jemdet Nasr in Mesopotamia), whereas Linear Elamite is attested for a similarly brief period in the last quarter of the 3rd millennium BC.
Inscription corpus 
The Proto-Elamite writing system was used over a very large geographical area, stretching from Susa in the west, to Tepe Yahya in the east, and perhaps beyond. The known corpus of inscriptions consists of some 1600 tablets, the vast majority unearthed at Susa.
Proto-Elamite tablets have been found at the following sites (in order of number of tablets recovered):
- Susa (more than 1500 tablets)
- Malyan (more than 30 tablets)
- Tepe Yahya (27 tablets)
- Sialk (22 tablets)
- Jiroft (two tablets)
- Ozbaki (one tablet)
- Shahr-i-Shokhta (one tablet)
None of the inscribed objects from Ghazir, Chogha Mish or Hissar can be verified as Proto-Elamite; the tablets from Ghazir and Choga Mish are Uruk IV style or numerical tablets, whereas the Hissar object cannot be classified at present. The majority of the Sialk tablets are also not proto-Elamite, strictly speaking, but belong to the period of close contact between Mesopotamia and Iran, presumably corresponding to Uruk V - IV.
Decipherment attempts 
Although Proto-Elamite remains undeciphered, the content of many texts is known. This is possible because certain signs, and in particular a majority of the numerical signs, are similar to the neighboring Mesopotamian writing system, proto-cuneiform. In addition, a number of the proto-Elamite signs are actual images of the objects they represent. However, the majority of the proto-Elamite signs are entirely abstract, and their meanings can only be deciphered through careful graphotactical analysis.
While the Elamite language has been suggested as a likely candidate underlying the Proto-Elamite inscriptions, there is no positive evidence of this. The earliest Proto-Elamite inscriptions, being purely ideographical, do not in fact contain any linguistic information, and following Friberg's 1978/79 study of Ancient Near Eastern metrology, decipherment attempts have moved away from linguistic methods.
In 2012, Dr Jacob Dahl of the Faculty of Oriental Studies, University of Oxford, announced a project to make high-quality images of Proto-Elamite clay tablets and publish them online. His hope is that crowdsourcing by academics and amateurs working together would be able to understand the script within two years, despite the presence of mistakes and the lack of phonetic clues.
