Collado, Diego a Spanish Dominican, was born at Mezzadas, in Estremadura. He assumed the habit of his order at Salamanca in 1600. After having taught belles- lettres, he embarked for Japan in 1619, and, in spite of persecution, preached the Gospel for several years. In 1625 his superiors sent him to Rome to solicit of the pope more extended powers. While in Europe he published several works, the material for which he had collected in his travels. Urban VIII having at length delivered a brief favorable to the wishes of the missionaries, Collado went to Spain in 1632, obtained of the king letters-patent for the foundation of a convent of his order in the Philippine Islands, and embarked again in 1635. Arriving there, he met with much opposition from the governor, but nevertheless succeeded in carrying out his project. Being recalled to Spain in 1638, he embarked, but the ship was wrecked, and he perished. His works are, Ara Grammatica Linguae Japonicae (Rome, 1631): — Dictionarium sive Thesauri Linguae Japonice (ibid.; compendium, 1632): — Historia Ecclesiastica de las Successas de la Christiandad de. Japon (Madrid, 1632): — Modus Confitendi et Examenandi Poenitentem Japonensem, etc. (Rome, 1631):
