Oppressed with melancholy, he moved to a garret, where he surrounded himself with dogs, cats and birds, which he had befriended; he became utterly careless of cleanliness or food, and sought comfort only in smoking.
The spirit of rivalry induced Voltaire to take the subjects of no less than five of Crébillon's tragedies (Semiramis, Electre, Catilina, Le Triumviral and Ahreeas) as his own.
The so-called Éloge de Crébillon (1762; the title meant ironically), which appeared in the year of the poet's death, was generally attributed to Voltaire, though he strenuously denied the authorship.
A complete bibliography is given by Maurice Dutrait in his Étude sur la vie et le théâtre de Crébillon (1895).
