Juan de Mena (1411–1456) was one of the most significant Spanish poets of the fifteenth century. He was highly regarded at the court of Juan II de Castilla, who appointed him veinticuatro (one of twenty-four aldermen) of Córdoba, secretario de cartas latinas (secretary of Latin letters) and cronista real (royal chronicler). His works show the influence of Renaissance humanism and place him in the period of transition in Spain from the Middle Ages to the Renaissance.
