ULLOA, Francisco de, Spanish friar, born in Andalusia about 1498; died in Seville in 1574. He united with the Dominicans at Salamanca, and was among the few that accompanied Bishop Vicente Valverde when he sailed for Cuzco in 1538. Ulloa was afterward prior of a convent in Lima, and visitor of the order. Having learned the Indian dialects, he explored the country, founded convents at Arequipa and Huanuco, and preached the gospel to the Indians in their own language with success. His influence was great in Peru, and Gonzalo Pizarro undertook to win him over to his cause, but Ulloa rejected his offers, and joined Pedro de La Gasca. The latter despatched Ulloa with letters and proclamations for the officials and inhabitants along the coast, and instructed him to buy supplies and prepare everything for the advance of the royal army. Ulloa's mission was so successful that Pizarro sent a party of cavalry that succeeded in taking him a prisoner, and he was carried to Lima, where he was imprisoned and suffered greatly. When peace was restored, La Gasca despatched Ulloa to Spain, in 1549, but he shortly afterward returned to this country and went to Caracas, being later made visitor of the province of Guatemala. Toward the close of his life he retired to Seville, where he died with the reputation of a saint. He wrote a curious account of his voyage from Panama to Peru, published in the 44th volume of Antonio Salva's collection, and contributed memoirs to the council of the Indies, printed in "Cartas de Indias" (Madrid, 1872).
