JACOB ÇADIQUE (ẒADDIḲ):
Spanish physician and writer; born at Ucles in the second third of the fourteenth century. He devoted himself to the study of medicine, and became body-physician to D. Lorenzo Suarez de Figueroa, Maestre de Santiago, from whom he received a commission to translate from the Limousinian into the Castilian dialect a moral-philosophical work containing proverbs and sayings from the Old and New Testaments and from the works of Aristotle, Seneca, Cicero, and others. This work, entitled "Libro de Dichos de Sabios é Filosofos," and consisting of seven parts, was finished in Velez July 8, 1402, and is still extant in manuscript in the Escurial. Whether Jacob Çadique was baptized, as Amador de los Rios states, is not certain.
