Diego of Deza

A brief biography.

Diego of Deza, theologian, archbishop, patron of Christopher Columbus, was born  at Toro, 1444. 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 Jaen, of Palencia; Archbishop of Seville (1505).

In 1523 he was appointed Archbishop of Toledo and Primate of Spain, but died 9 June 1523,  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).


Diego of Deza was a friend of Columbus, and patronized 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."
