Theologian, archbishop, patron of Christopher Columbus, b. at Toro, 1444; d. 1523. Entering the Order of St. Dominic in his youth, he became successively: professor of theology at St. Stephen's, Salamanca; tutor to Prince John, son of Ferdinand and Isabella; Bishop of Zamora, of Salamanca, of Jaén, of Palencia ; Archbishop of Seville (1505). In 1523 he was appointed Archbishop of Toledo and Primate of Spain, but died before he had taken possession of that see. He left several theological works, the principal one being a "Defensorium Doctoris Angelici, S. Th. Aquinatis" (Seville, 1491). Historians generally have not emphasized the importance of Deza's friendship for Columbus and the bearing of this friendship and patronage on the discovery of America. In a letter dated 21 Dec., 1504, Columbus wrote to his son Diego: "The Lord Bishop of Palencia (Diego Deza) has always favoured me and has desired my glory ever since I came into Castile." Then he added this most significant declaration: "He is the cause of their Highnesses' possessing the Indies, and of my remaining in Castile, when I was already on the road with the intention of leaving it."

Catholic Encyclopedia

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
