A Marano, ship-physician on the first voyage of Columbus to America. He had lived in Tortosa and had undergone public penance in October, 1490, as an adherent of Judaism. Columbus, by his arrogant conduct, aroused the enmity of the physician, who instigated a conspiracy against the admiral in Jamaica which seriously affected his destiny.
