This Great Jew had once been the beardless twelve-year-old João Micas on the Bristol-bound caravel in 1537 with his aunts, Beatriz and Brianda de Luna. Now he was Duke of Naxos, master of an Aegean empire of castles and islands – lord of Milos, Paxos, Paros, Antiparos, Andros, Santorini (which itself produced potent wines from its volcanic soil) – and was known among his own people as Don Joseph Nasi, the prince.
