The most famous of his plays is "La verdad sospechosa", (published in 1634). The first great French comedy in modern French literature, Corneille's "Le menteur" ("The Liar"), was confessedly modeled after it. "Las paredes oyen" ("Walls have Ears") is often seen as a companion-piece since both plays deal with mendacity. His plays can be divided into at least three distinct categories: social comedies, political dramas and plays that dramatize astrology, magic and other occult practices. Among the political plays, "El dueño de las estrellas" stands out as a stunning tragedy, dealing with Lycurgus, the Spartan lawgiver. Although the oracle had predicted that he would either kill a king or be killed by one, when faced with the dilemma he commits suicide thus overcoming the power of the stars. A second political play, "La amistad castigada", is unusual because the king is deposed at the end. The magic plays include astonishing instances of the occult at a time when such practices were frowned upon. See, for example, "La cueva de Salamanca" and "La prueba de las promesas". "Quien mal anda, mal acaba" may be the first Spanish play that dramatizes a pact with the devil. Indeed, even in social comedies such as "Las paredes oyen" we can encounter extensive astrological allusions.
