French poet and dramatist of the pre-Neoclassical period.

Born into a Huguenot family of the minor nobility, Viau went to Paris, where he soon won a reputation as the leader of the freethinkers (libertins). He was briefly house dramatist to the Hôtel de Bourgogne in Paris, writing one important tragedy, Pyrame et Thisbé (1623). This period of prosperity ended when he was charged with irreligious activities. He fled, was sentenced in absentia to death, was rearrested, and was finally released in 1625 under sentence of banishment. His health broken, he died soon afterward.

Viau wrote odes and other poems on a wide range of topics. His verse is marked by a strong feeling for nature, great musicality, a use of original and ingenious imagery, and an epicurean outlook that is tempered by apocalyptic visions and the thought of death. He defended spontaneity and inspiration against the set of literary rules laid down by the influential poet François de Malherbe (Malherbe, François de). Viau's poetry was rediscovered by the Romantics in the 19th century.
