Pintados Islands. In his report (dated 20 March 1579) regarding a campaign to pacify the natives living along the rivers of Mindanao (a mission he received from Dr. Francisco de Sande, Governor and Captain-General of the Archipelago), Ribera mentioned that his aim was to make the inhabitants of that island "vassals of King Don Felipe… as are all the natives of the island of Panay, the Pintados Islands, and those of the island of Luzon…" During the early part of the colonial period in the Archipelago, the Spaniards led by Miguel López de Legazpi transferred their camp from Cebu to Panay in 1569. On 5 June 1569, Guido de Lavezaris, the royal treasurer in the Archipelago, wrote to Philip II reporting about the Portuguese attack to Cebu in the preceding autumn. A letter from another official, Andres de Mirandaola (dated three days later, 8 June), also described briefly this encounter with the Portuguese. The danger of another attack led the Spaniards to remove their camp from Cebu to Panay, which they considered a safer place. Legazpi himself, in his report to the Viceroy in New Spain (dated 1 July 1569), mentioned the same reason for the relocation of Spaniards to Panay. It was in Panay that the conquest of Luzon was planned, and later launched on 8 May 1570. The account of early Spanish explorers During the early part of the Spanish colonization of the Philippines, the Spanish Augustinian Friar Gaspar de San Agustín, O.S.A. described Panay as: "…very similar to that of Sicily in its triangular form, as well as in it fertility and abundance of provision. It is the most populated island after Manila and Mindanao, and one of the largest (with over a hundred leagues of coastline). In terms of fertility and abundance, it is the first. […] It is very beautiful, very pleasant, and full of coconut palms… Near the river Alaguer (Halaur), which empties into the sea two leagues from the town of Dumangas…, in the ancient times, there was a trading center and a court of the most illustrious nobility in the whole island." Padre Francisco Colin (1592–1660), an early Jesuit missionary and Provincial of his Order in the Philippines also records in the chronicles of the Society of Jesus (published later in 1663 as Labor euangelica) that Panay is the island which is most abundant and fertile.
