Navarrete gives, No. XX of his documents relating to Magellan, a copy of a document presented on Wednesday, the 22nd of May, 1521, by a servant of Diego Barbosa, on behalf of Alvaro de Mezquita, to the Alcalde of Seville, dated April 26th, 1520, which were the informations taken in Port St. Julian by Martin Mendes, clerk of the Victoria; Sancho de Heredia, king's notary; Gonzalo Gomes de Spinosa, Alguazil-mayor or chief constable of the fleet: he could not write, and Domingo de Barruty signed for him.

These informations were taken in consequence of a petition from Alvaro de Mezquita, captain of the S. Antonio, to Magellan, complaining of Gaspar de Quesada, captain of the Conception, and Juan de Cartagena, with about thirty armed men, having seized him the night of Palm Sunday, April 1st, 1520, and having locked him up in the cabin of Geronimo Guerra, the clerk of the S. Antonio. This petition was presented to Magellan when he was on shore, after hearing Mass on Sunday, the 15th of April, and he gave orders to the two clerks and Alguazil to make an inquiry on board the S. Antonio. His order was dated April 17th, and signed by himself and Leon de Speleta, clerk of the flag-ship. The informations taken on board the S. Antonio were dated Thursday, the twenty-sixth April, 1520.
