In 1492 Antonio de Nebrija published his celebrated "Gramática de la lengua castellana" ("Grammar of the Castilian language"), the first such work for a modern European language. In 1528 Francisco Delicado wrote "", a novel in the orbit of "La Celestina", and in 1599 the Sevillian Mateo Alemán wrote the first part of "Guzmán de Alfarache", the first picaresque novel with a known author.
