La cité de Séleucie-sur-le-Tigre aux époques séleucide et arsacide

The city of Seleucia on the Tigris was founded in the 4th century BCE by Seleucos I, one of Alexander’s empire’s Successors. According to the size of it’s original dwelling-blocks, it was designed from the start to be a large and important city. It flourished for some time and became an administrative center and royal residence. In 129 BCE, it was conquered by the Arsacids, a rival dynasty. Seleucia’s development continued unbroken, but the city eventually declined and disappeared around 200 CE. To explain this change, historians underlined the importance of the perceived culture of its old and new sovereigns. Ruled by the Macedonian Seleucids, the city prospered. Under the Iranian Arsacids’ hostile administration, it was ill-treated until it got abandoned. Such analyses have been based on some passages of ancient texts insisting on the Greek character of Seleucia and its inhabitants. Those also influenced the interpretation of the results of the first archaeological digs conducted on the site. This thesis comes back on the relations between the city and both its Seleucid and Arsacid kings in order to evaluate the importance of this supposed cultural rivalry in the development of Seleucia. It compares the written tradition, essential but biased by political imperatives, and the buildings, coins, seals and figurines discovered by American, German and Italian archaeologists between 1927 and 1989. Our results suggest that the city and its population were of a mixed cultural backround and that its supposed Greek character did not play much of a role in its decline. We therefore suggest that other factors explain the disappearance of Seleucia, such as the Tigris changing bed and an evolution in the geopolitical situation of the Near East around 200.
