Mahuza

Mahuza (in Hebrew and Aramaic sources, particularly Jewish ones, Maḥuza) is the name given to the metropolis formed by Ctesiphon and Seleucia on opposite sides of the Tigris River. It was one of the cites of an early Babylonian Talmudic yeshiva, founded by Rava, as well as the original seat of the Exilarch.
