Though his drama Le Cid (1637), inspired by a twelfth century Spanish narrative, provoked a critical controversy over its violation of classical standards, Corneille came to be regarded as one of the greatest French dramatists of his time. A non-exhaustive list of his many works includes Horace (1640), Cinna (1643), Polyeucte (1643), La Mort de Pompée (The Death of Pompey, 1644), the comedy Le Menteur (The Liar, 1644), Rodogune (1645), Théodore (1646), Héraclius (1647), Andromède (1650), La Toison d'or (The Golden Fleece, 1660), Sertorius (1662), Othon (1664), Agésilas (1666), Attila (1667), Psyché (1671, a comedy in collaboration with Molière), and his unsuccessful last play, Suréna (1674). Corneille also authored criticism and translations, including Trois discours sur le poème dramatique (Three Discourses on Dramatic Poetry, 1660), a defense of his methods in Le Cid hinging on the assertion that Aristotle's principles were never meant to be strictly literal.
