OSORIO, Hieronymo, a Portuguese author, born in Lisbon in 1506, died in Tavira, Aug. 20, 1580. He studied at Salamanca, Paris, and Bologna, and became archdeacon of Evora, and subsequently bishop of Silves. At the request of Cardinal Henrique he wrote in Latin a history of the reign of King Emanuel (translated into English by James Gibbs, 2 vols. 8vo, London, 1752). Among his other works is a treatise De Gloria Libri V, so much admired for its pure Latinity that he has been called the Cicero of Portugal. A complete collection of his works was published in Rome by his nephew (4 vols. fol., 1592). His library was taken from Cadiz by Lord Essex in 1596, and added to the Bodleian library.
