Chapentier showed at the exhibitions organized by the alternative Académie de Saint-Luc, where he was a member and a professor, as well as at the Salon de la Correspondance and at the annual official Salon after the Revolution had opened it to all artists. He is known today for the amusing genre scenes that he regularly submitted to these exhibitions, but he seems to have made a living working as 'peintre ordinaire' to the household of the Duc de Penthièvre, for whom he principally executed portraits (see lot 159 in this sale for a portrait of the Duc de Penthièvre).
Charpentier is often compared to his more famous contemporary, Jean-Baptiste Greuze, with whom he shared a taste for sentimental subjects touched with an erotic undercurrent; but unlike Greuze, Charpentier specialized in genre scenes in the fashionable 'goût hollandais'. In fact, the subject of The Analysis will be immediately recognizable as a favorite of such Dutch 17th century
artists as Frans van Mieris I, Jan Steen, Gerard Dou and Godfried Schalcken. A bonneted doctor -- probably a quack -- holds a urine vial up to the light in order to analyse its color. The protective gesture and withdrawn melancholy of the pretty young patient, eager concern of her parents, and sudden arrival of her worried lover, suggest what the diagnosis will be: la maladie d'amour, pregnancy.
