Pierre Corneille (French pronunciation: [pjɛʁ kɔʁnɛj]; Rouen, 6 June 1606 – Paris, 1 October 1684) was a French tragedian. He is generally considered one of the three great seventeenth-century French dramatists, along with Molière and Racine. As a young man, he earned the valuable patronage of Cardinal Richelieu, who was trying to promote classical tragedy along formal lines, but later quarrelled with him, especially over his best-known play, Le Cid, about a medieval Spanish warrior, which was denounced by the newly formed Académie française for breaching the unities.
