This paper studies the presence of Fray Luis de León in the literary and critical work of Antonio Colinas. In addition to the lyrical homages dedicated to the Augustinian friar in Noche más allá de la noche, Tiempo y abismo, and Canciones para una música silente, Antonio Colinas, an excellent essayist, interprets Fray Luis in the light (mystical, lato sensu) of reasoned music, a wise symbol of poetic art, inspired reason and harmony between word and world.
