Ambrosio, a Spanish historian and antiquary, was born at Cordova in 1513. After studying at the university of Salamanca under his uncle Fernan Perez de Oliva, he assumed the garb of the Dominicans at the age of nineteen, and became a strict and zealous ecclesiastic. At the same time his literary abilities were raising him to notice. He was afterwards appointed a professor at Alcala, and his learning as an antiquary procured for him in 1570 the office of historiographer to Philip II. It was at this period, when he was sixty-seven years of age, that he began to write his continuation of Ocampo's Chronicle of Spain. He had brought down the narrative as far as the union of the crowns of Castile and Leon, when he died in 1591. The best edition of Morales' Chronicle is that of Madrid, 6 vols. 4to., 1791. To this are generally added his Spanish Antiquities, 2 vols., 1792, and his miscellaneous works, 3 vols., 1793.
