French dramatist of some skill and originality who was considered in his day the rival of Voltaire.

Crébillon's masterpiece, the tragedy Rhadamiste et Zénobie (produced 1711), was followed by a run of failures, and in 1721 he retired from literary life. He returned, however, in 1726 with Pyrrhus, which was successful, and he wrote for another 20 years. He was elected to the Académie Française in 1731 and became dramatic censor in 1735.

Crébillon's tragedies were modeled after those of the Roman tragic writer Seneca and, like them, bordered on melodrama. His specialty was horror: according to his preface to Atrée et Thyeste (1707), he aimed to move the audience to pity through terror. In private life he was an eccentric who lived in virtual seclusion in a barely furnished apartment and befriended birds and animals.
