In 1976, a singular Antonio Buero Vallejo (Guadalajara, 1916 - Madrid, 2000) states "Sloth is the most beautiful of all vices." He revisits his trajectory: "To me, writer, I do not like to write, so that I work little, that is the truth. Keep in mind that I have been in the theater for 27 years and I have released 20 pieces in round numbers." The appearance of his first work, Historia de una escalera (1947), is "a kind of breaking point in Spanish theater. I was simply trying to write a theater according to my sensitivity and in accordance with my concerns. " His later works include The Skylight (1967) and The Dream of Reason (1969): "In my theater there is a certain quixotic vein. I think one of my literary influences is that of Cervantes, and that of Don Quixote. "
