PORTILLO, Jacinto de (por-tee'-yo), later known as FRAY CINTO, Spanish soldier, born in Spain about 1490; died in Nombre de Dios, Mexico, 20 September, 1566. He went to Cuba as a soldier with Diego de Velazquez, and took part in the exploration of the coast of Mexico under Juan de Grijalva in 1519. He also participated in the conquest of Mexico, afterward went with eight of his comrades to explore the northwest coast, and, having suffered great hardships, reached the South sea, taking possession of it in the name of the emperor, as he relates in a letter to Philip II., dated Mexico, 20 July, 1561. As a reward for his services, the emperor gave him the Indian commanderies of Huitzitlapan and Tlatanquitepec, where he acquired a great fortune. About 1563 he abandoned his adventurous life for a life of penitence, distributed his riches among the poor, and as a priest devoted himself to the conversion of the natives in the province of Zacatecas. Fray Cinto displayed much zeal in his new vocation and met with great success. With Friar Pedro de Espinadera he founded the town of Nombre de Dios, and many Christian congregations. He died, after a residence in New Spain of nearly half a century, in the convent of the town that he had founded.
