Menachem ben Aaron ben Zerach (born 1310, died 1385) counted several martyrs in his family. His father, Aaron, was one of the unfortunates whom the cupidity and tyranny of a French king had banished. With the limited means spared by legalized robbery he had settled in Estella, a not inconsiderable Navarrese community. His father, mother, and four brothers perished in the massacre of Jews instigated by a Dominican friar. Young Menachem was severely wounded in this outbreak, and might have succumbed but for the assistance of a nobleman of his father's acquaintance. On his recovery he devoted himself daily to Talmudical study, and later on attended the celebrated school of the Asheride Judah of Toledo. After he had passed his fortieth year, Menachem ben Zerach became chief of an academy, the care of which was confided to him by the Alcala (de Henares) community. During the civil war in Castile he was wounded and plundered by the lawless soldiery, and of his entire fortune, only his house, field, and collection of books remained. Don Samuel Abrabanel assisted him in his distress, so that he was enabled to recover somewhat from his misfortunes. Through his interposition Menachem was called from Alcala to assume the rabbinate of Toledo, where he opened an academy. As the disciple and successor of Jehuda Asheri, considerable Talmudical attainments were with justice expected of him. But he did not rise above the mediocrity of his times. To remedy the increasing ignorance of religious forms and duties, he wrote a compendium of theoretic and practical Judaism ("Zeda la-Derech," 1374), as comprehensible as it was short, for the use of prominent Jews, who, employed at court and by the grandees, had not sufficient leisure to search an extensive literature for instruction. His work is interspersed with scientific elements--psychological and religio-philosophical--but it is weak and commonplace, full of platitudes, and its several parts do not cohere. Even the Talmudical elements are neither profound nor original. The only redeeming feature is that it is conceived in a warm, sympathetic spirit, distinguishing it from the usually dry rabbinical disquisitions.
