This oil on panel (47 x 36 cm) by Jean-Jacques Lagrenée (1739-1821), representing an ancient Sacrifice, probably comes from the sale after death of Louis-François de Bourbon, Prince of Conti, which took place in Paris from April 6 to 8, 1777. It would have been presented there under the number "751" and the title Sacrifice de la poule. Despite the differences in dimensions and support, common errors in the catalogs of the time, the drawing of Gabriel de Saint-Aubin made during the Conti sale and now kept at the National Library of France tends to confirm this provenance (M. Rémy). A pupil of his older brother Louis-Jean-François Lagrenée, Jean-Jacques Lagrenée stayed with him in Russia from 1760 to 1762, then at the Académie de France in Rome from 1765 to 1769. He took a close interest in the excavations of Herculaneum and Pompeii and made numerous surveys on the spot. Back in France, he turned to history painting. Accredited by the Royal Academy in 1769, he exhibited regularly at the Salon of 1771 and 1804. On , he was received at the Academy with the Winter Ceiling of the Galerie d'Apollon at the Louvre. In 1776, he was appointed assistant professor and then full professor, replacing Jean-Baptiste d'Huez. In 1784, he published a collection of plates engraved from the antique, providing a whole repertoire of motifs, friezes and various ornaments, from his surveys made in the Naples region. In 1785, the Comte d'Angiviller, who wanted to promote a return to the antique, appointed him co-artistic director of the Manufacture de Sèvres. With his colleague Boizot, he is the author of the Etruscan service for the Rambouillet dairy, including the famous bol-sein.
