One characteristic of the Parthians that the kings themselves maintained was their nomadic urge. The kings built or occupied numerous cities as their capitals, the most important being Ctesiphon on the Tigris River, which they built from the ancient town of Opis.
In the Middle Persian period (Parthian and Sassanid Empires), Aramaic was the medium of everyday writing, and it provided scripts for writing Middle Persian, Parthian, Sogdian, and Khwarezmian.
The Parthians and the peoples of the Parthian empire were polytheistic. Each ethnic group, each city, and each land or kingdom was able to adhere to its own gods, their respective cults and religious rituals. In Babylon the city-god Marduk continued to be the main deity alongside the goddesses Ishtar and Nanai, while Hatra's main god, the sun-god Shamash, was revered alongside a multiplicity of other gods.
