Ctesiphon, a city of Babylonia, on the eastern bank of the Tigris and opposite Seleucia, the common winter residence of the Parthian kings, and finally the capital of the Parthian kingdom. It was conquered by the Romans in 115 A.D., and destroyed by the Arabs under Omar in 637. Its ruins still attest its former magnificence.
