Pierre Corneille is one of the pillars of French theater, known for his tragedies and comedies that revolutionized the theatrical scene of his time. His most famous work, 'Le Cid' (1637), caused controversy and established the foundations of French classicism with its rigorous adherence to the rules of unity and verisimilitude. Corneille explored themes such as honor, duty, passion, and moral conflict, creating complex characters and profound ethical dilemmas. He was also one of the first authors to professionalize theatrical writing, seeking recognition and sustenance through his art. Other important works include 'Horace', 'Cinna', and 'Polyeucte'. His writing influenced generations of playwrights and consolidated classical tragedy as a literary genre of great prestige in France.
