Notwithstanding the valuable information the astronomer Zacato had given the King, he was compelled, with other Jews, to fly from Portugal, on account of the persecution to which they were subjected. The King, Dom Manoel, at once gave orders for the completion of the ships which Dom Joao had commenced, and directed that they should be as strong and serviceable as possible. The sailors who had gone on a previous expedition were collected, and the ships were supplied with double the usual amount of sails and tackling, as well as with artillery, munitions, and provisions, including all sorts of fruits, especially preserves, for the use of the sick, nor were priests for confession forgotten. Rich merchandise, and gold and silver articles, goblets, swords and daggers, shields and spears, all highly ornamented, fit to present to the rulers of the countries to be visited, were also collected. All the slaves to be found, who could speak Eastern languages, were purchased, that they might act as interpreters. The King having made these preparations, had next to fix on a leader for the expedition. Among the cavaliers who attended his Court was one who had already seen much service at sea, Vasco da Gama, a man of noble lineage, son of Estevan da Gama, formerly Comptroller of the Household of King Dom Alfonso. The King, summoning Vasco into his presence, offered him the command of the squadron he proposed sending out to discover a way to the East Indies by sea. The cavalier at once gladly accepted the honourable charge, saying at the same time that he had an elder brother, named Paulo da Gama, whom he requested the King to appoint as Captain-Major to carry the royal standard. The King, pleased with his modesty, and satisfied that he was a man especially fitted for the undertaking, granted him his request, but desired that he himself should carry out all the arrangements for the expedition.
