A student of the painter Jean François Millet and a lithographer of scenes of daily life, costume, and erotica in the 1820s and 1830s, Vallou reportedly took up photography in the early 1840s, but his early photographs have not been identified. Perhaps they depicted naked women, a subject for which it was improper to acknowledge authorship. Between 1851 and 1855, however, Vallou made a series of photographs of female nudes that he marketed (and legally registered) as models for artists. Vallou’s nudes have long been associated with those of Gustave Courbet, who is known to have used photographs in his painting process. Although no absolute one-to-one correspondence can be pointed to, the heavy soporific quality of Vallou’s models is very close to Courbet’s concept of the nude, and the reclining figure displayed here is strikingly similar in pose to the painter’s Woman with a Parrot (1866), on view in the galleries for nineteenth-century painting.
