Antonio de Nebrija (14445 July 1522) was the most influential Spanish humanist of his era. He wrote poetry, commented on literary works, and encouraged the study of classical languages and literature, but his most important contributions were in the fields of grammar and lexicography. Nebrija was the author of the Spanish Grammar (Gramática de la lengua castellana, 1492) and the first dictionary of the Spanish language (1495). His grammar is the first published grammar study of any modern European language. His chief works were published and republished many times during and after his life and his scholarship had a great influence for more than a century, both in Spain and in the expanding Spanish Empire. Name Nebrija was baptized . In typical Renaissance humanist fashion, he Latinized his name as (or in Spanish) by taking Aelius from the Roman inscriptions of his native Lebrija, known in Roman times as . He was also known as , , and . Biography Nebrija was born into an hidalgo family in Nebrixa, a town now called Lebrija in the province of Seville. His parents were Juan Martínez de Cala and Catalina de Xarana. He was the second of five children. There is some uncertainty about his date of birth. Nebrija wrote that he was born the year before the Battle of Olmedo in 1445, putting his birthday in 1444 but elsewhere he makes other references that would contradict this date. Traditionally, 1444 has been accepted as his year of birth. At age fourteen, Nebrija enrolled at the University of Salamanca, where he studied mathematics, philosophy, law and theology. These latter topics earned him a scholarship from the bishopric of Seville to study theology at the Royal College of Spain in Bologna. Little is known about his studies in Italy except that he was inspired by the works of the Italian humanists, especially Lorenzo Valla. After ten years in Italy Nebrija returned to Spain armed with the new concepts of Renaissance humanism. Once back in Spain, Nebrija served Alonso de Fonseca y Ulloa, archbishop of Seville, for three years. When Fonseca died in 1473, Nebrija returned to the University of Salamanca as a lecturer. In 1476 he was appointed First Chair of Grammar and in 1481 he published his first work, the Introductiones latinae (Introduction to Latin), a textbook on Latin grammar and literature. The first printing of 1,000 copies quickly sold out and
