Note 53 — NAVIGATION AND VOYAGE WHICH FERNANDO DE MAGALHĀES MADE FROM SEVILLE TO MALUCO IN THE YEAR 1519.
Henry Edward John Stanley Stanley translation
Some writers remark that Magellan gave to these islands the name of Ilhas das velas, on account of the many vessels with sails which he observed in that neighbourhood. But they continued to be commonly called Ladrones; later they took the name of Mariannas, in honour of the Queen D. Marianna of Austria, widow of Philip IV, and Regent during the minority of D. Carlos II. of Castile. Lisbon Ac. note.
