Spanish physician and rabbinical scholar; lived at Constantinople in the sixteenth century. He was court physician to Sulaiman the Great, and followed the latter's army into Syria. Several years after his return to Constantinople the Jews of Damascus requested him to settle in their city. He was also known as a Talmudist, and he cosulted Joseph Caro on rabbinical matters. A responsum of his is to be found in Caro's "Abḳat Rokel" (No. 27). In his only published work, "Kebod Elohim" (Constantinople, 1585), he gives an account of his travels and of the customs of the Kurds and Druses. Another work of his is entitled "'Emeḳ ha-Siddim."
