Abraham Cresques
Abraham Cresques (1325–1387), whose Hebrew name was Elisha ben Abraham, was a Jewish cartographer of Palma on Majorca and a leading figure of the Majorcan cartographic school. He made his living as a master map-maker and builder of clocks, compasses and nautical instruments.
Together with his son Jehuda Cresques he drew the Catalan Atlas, conventionally dated 1375, a six-leaf world map on vellum counted among the finest medieval maps.
