La Celestina
Medieval Spanish literature consists of the corpus of literary works written in medieval Spanish between the beginning of the 13th and the end of the 15th century. Traditionally, the first and last works of this period are taken to be respectively the "Cantar de Mio Cid", an epic poem whose manuscript dates from 1207, and "La Celestina" (1499), a work commonly described as transitional between the medieval period and the Renaissance.
