 Fais was therefore charted as "Matelotes".Having known about this story, António Galvão governor of Ternate at the time, in his "Tratado dos Descubrimientos" of 1563 says that this was because he had sent one Francisco de Castro as commander of a ship on a proselytizing mission to the islands discovered in the area of Fais by the Portuguese Diego da Rocha (Ulithi in 1526).However, while this could be a natural explanation of the incident, it doesn't explain why, according to Villalobos' records the local people greeted them in "perfect" Spanish and not in Portuguese.
