Raba Ben Joseph Ben Hama (c. 280-352) was a Jewish Talmudist who lived in Babylonia, known as an amora. He is closely associated in his studies with Abaye. The latter was head of the Academy at Pumbeditha. Raba founded a new school at Mahuza, which eventually became, so long as Raba lived, the only academy in Babylonia. The development of Talmudic Law (or Halakhah) was much indebted to this rabbi, whose influence in all branches of Jewish learning was supreme. Wikipedia
