Luis Ponce De Leon (usually called in Spanish Fray Luis de Leon), a Spanish lyric poet, born in Granada about 1527, died in Madrigal, Aug. 23,1591. He entered the Augustinian order at the age of 16, became licentiate in theology in 1560, and doctor of divinity shortly afterward, and at the age of 34 obtained a professorship of theology at Salamanca, where he himself had studied. Ten years later he was made professor of sacred literature. For the benefit of some friends he made a literal version of the Canticles into Castilian; and the manuscript falling into the hands of his enemies, he was brought before the inquisition of Valladolid in 1572, on a charge of Lutheranism. He was fully reinstated in December, 1576. His original productions, which stand at the head of Spanish lyrical and heroic poetry, are few but remarkable alike for elevation of style and purity of diction; the best are La profecia del Tajo, La mda retirada, La im mortalidad, La noche serena, and La Ascension. They were first published by his friend Que-vedo in 1631. His most popular prose work is his Perfecta casada, or "Perfect Wife," a treatise in the form of a commentary on portions of the book of Proverbs. Among his other prose works are the Exposition de los Salmos and De los nombres de Cristo. The best edition of his works is that of Madrid (6 vols., 1804-'16).
