Lyric poetry in the Middle Ages can be divided into three groups: the jarchas, the popular poems originating from folk-songs sung by commoners, and the courtly poetry of the nobles. Alfonso X el Sabio fits into the third group with his series of three hundred poems, written in Galician: Las cantigas de Santa María. Another poet, Juan Ruiz, or the Arcipreste de Hita is an outstanding lyricist of the fourteenth century. His only work, Libro de buen amor is a framework tale in which he includes translations from Ovid, satires, little poems called serranillas, twenty-nine fables, a sermon on Christian armor, and many lyric poems that praise the Virgin Mary. Poet Íñigo López de Mendoza, the Marqués de Santillana (1398-1458) begins to show the movement away from the traditions of the Middle Ages. He shows a knowledge of Latin authors and familiarity with the works of Dante and Petrarch. Mendoza was also the first to introduce the sonnet into Spanish literature. The last great poet of the Middle Ages is Jorge Manrique. He is famous for his work which laments the death of his father, Coplas a la muerte de su padre. In this piece, Manrique shows classical feelings by expressing himself in a universal manner (all things come to an end). He is still considered a poet of the Middle Ages in that he finds peace and finality in religion.
