 Rav Ashi's son Tabyomi (known as Mar bar Rav Ashi) was a recognized scholar, but only in 455, 28 years after his father's death, did he receive the position that his father had so successfully filled for more than half a century.His commanding personality, his scholarly standing, and wealth are sufficiently indicated by the saying, then current, that since the days of Rabbi Judah haNasi, learning and social distinction were never so united in one person as in Rav Ashi.Indeed, just as Judah haNasi compiled and edited the Mishnah; Rav Ashi made it the labor of his life to collect and edit under the name of Gemara, the explanations of the Mishnah which had been taught in the Babylonian academies since the days of Rav, together with all the discussions connected with them, and all the halakhic and aggadic material covered in the schools.
