John of Capua

John of Capua (fl. 1262-1269) was an Italian Jewish convert to Christianity, and a translator. He translated Rabbi Joel's Hebrew version of Kalilah wa-Dimnah into Latin under the title Directorium Vitae Humanae. His translation was the source from which that work became so widely spread in almost all European languages. It was edited by Joseph Derenbourg (Paris, 1887). John of Capua also translated Maimonides' Dietary and Ibn Zuhr's (Avenzoar's) Al-Taisir, on diseases.
