There are two versions of the Gemara. The Jerusalem Talmud (Talmud Yerushalmi) or Palestinian Talmud was compiled by Jewish scholars of the Land of Israel, primarily of the academies of Tiberias and Caesarea, and was published between about 350–400 CE. The Talmud Bavli (Babylonian Talmud) was published about 500 CE by scholars of Babylonia, primarily of the academies of Sura, Pumbedita, and Nehardea. By convention, a reference to the "Gemara" or "Talmud," without further qualification, refers to the Babylonian version. The main compilers were Ravina and Rav Ashi.
