Published in 1829, Les métamorphoses du jour presages J.J. Grandville’s later effort album of anthropomorphic images, Scènes de la vie privée et publique des animaux (Scenes of the Private and Public Life of Animals) and features comical burlesque images meant to satirize people from various walks of Parisien society (with often witty choices of animal meant to represent different sorts of people.) Gordon R. Ray writes in The Art of the French Illustrated book that,

Lust, gluttony, anger, and the other deadly sins are stigmatized, now with the blow of a hammer, now with the thrust of a stiletto; while the foibles and humors of mankind also receive due attention. Throughout the series Grandville’s choice of beast-heads is inspired; and the force of his conceptions and the wit of his captions rarely falter.
