Question: How old was Solomon Luria when they wrote their commentaries about Mizrachi? Passage:Sefer ha-Mizrachi is a supercommentary on Rashi's commentary on the Torah. It is counted in its own right as among the most important commentaries on the Torah. It was first published in Venice in 1527 after Mizrachi's death, by his son Israel. Mizrachi himself considered his commentary on Rashi the most important of his works (Responsa, Nos. 5, 78). The work shows Rashi's Talmudic and midrashic sources, and elucidates all obscure passages. It was written, partially, to defend Rashi from the strictures of the later commentators, particularly Nachmanides. A compendium by Jacob Marcaria was published under the title Kitzur Mizrachi (Trento, 1561), and later, one by Isaac ha-Kohen of Ostroh, entitled Mattenat 'Ani (Prague, 1604-9). Several commentaries have been written on Mizrachi, including Yeri'ot Shlomo by Solomon Luria (Maharshal), a supercommentary on Sefer ha-Mizrachi by Barzillai ben Baruch Jabez, and strictures on the work by Samuel Edels, (Maharsha).
