Nisĭbis
(
Νίσιβις), also called Antiochia
Mygdoniae. A celebrated city of Mesopotamia, and the capital of the district of
Mygdonia, stood on the river Mygdonius in a very fertile district. It was of great importance
as a military post. Its name was changed into Antiochia, but it soon resumed its original
name. In the successive wars between the Romans and the Parthians and Persians, it was several
times taken and retaken, until at last it fell into the hands of the Persians in the reign of Jovian (Strabo, pp. 522, 747; Ammian. Marcell. xxv. 9).
