The Mishnah isn’t compiled until the third century CE. Mishnah. Encyclopaedia Judaica. 14 (2 ed.). p. 319. ISBN 978-0-02-865942-8.. Heinrich Graetz, dissenting, places the Mishnah’s compilation in 189 CE (see: H. Graetz, History of the Jews, vol. 6, Philadelphia 1898, p. 105) The Mishnah then received commentary that is compiled as the “Gemara” The combination of the Gemara and the Mishna is called the Talmud. There are two versions of the Gemara. The Jerusalem Talmud (Talmud Yerushalmi) was compiled by 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 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.
