Spanish physician and diplomat of the fifteenth century, and court physician of the Duke of Bourbon (probably Louis II. of France). Alfonso V., King of Aragon, confided to him a mission to Pope Martin V. He went to Rome in charge of a letter to the pope (Sept. 8, 1420), under safe-conduct for a year. A few years later "Magister Elijah," while at Avignon, had a bull, issued in favor of the Spanish Jews, legalized by the notary of the Curia.
