Alfonso de Zamora (1474 – ) was a Jewish-Spanish scholar and a major contributor to the Complutensian Polyglot Bible. Like many Spanish Jews during the persecutions of the 15th century, Alfonso converted to Catholicism while privately remaining a Jew.
Biography
Born in Zamora, Spain in 1474, Alfonso was the son of Juan de Zamora, a learned Jew. He attended a Yeshiva, probably the famous Campanton Yeshiva until the age of 18, when he and his family left for Portugal in 1492, before returning in about 1497, already baptized. Historian Ahuva Ho argues that Alfonso likely continued to secretly practice Judaism for the rest of his life.
Alfonso was a professor of the Hebrew and Aramaic languages at the University of Salamanca until 1512, when he was moved to the University of Alcalá. In these letters, Alfonso describes himself as the last to remain among those exiled by the Alhambra Decree, and says that he has had not one day of happiness in his (almost) seventy years of life. He wrote many essays among them "How to Overcome the Plague;" "Loor de Virtudes," on Jewish and Spanish Proverbs; how to respond to the Inquisition tribunals; forced polemics against Jews and Judaism (as pretense to safeguard his secret life); and poems mostly bemoaning his and the Jews' suffering.
In 1526, Alfonso published , a second edition of a Hebrew grammar which he had originally contributed to the Polyglot Bible. This seven-chapter letter offers arguments for Christianity, Jesus, and the Trinity based on the Old Testament. Adolf Neubauer, a Hebrew scholar, describes the arguments as standard for their day, Ho calls their interpretations of scripture "distorted" and "out of context", and historian Paul Rieger questions whether the Jews of Rome actually received the letter at all.
In his many prayers to the God of Israel, he affirmed his faith. He concluded many of his essays on faith with the statement that the only way to survive was to practice the Torah's commandments. In his essays, translations, and annotations, he cited primarily the Jewish commentators Rashi, Radaq, Ibn Ezra, Rambam, Ramban, Ralbag, HaMeiri, and Ba'al HaTurim (A. Ho, "Alfonso de Zamora, the Crypto-Jew," Iberia Judaica XIII (2021): 15-45).
