a Spanish bibliographer, was knight of the order of St. Iago, and canon of Seville, where he was born, in 1617. He studied at Salamanca, and afterwards travelled to Rome as envoy of the king of Spain. While there, pope Alexander VII made him canon of the Cathedral of Seville, the income arising from which appointment he spent entirely in amassing a splendid library of more than thirty thousand volumes, by the aid of which he compiled his well-known Bibliotheca, or library of Spanish writers, in Latin (vol. iii and 4, Rome, 1672; vol. i and ii, ibid. 1696). A few treatises by him were collected (Antwerp, 1659). He died in Spain in 1684.
