Louis-Simon Boizot (1743-1809), director of the sculpture workshop at Sèvres from 1773 to 1800, modelled these figures for a Lampe antique in 1780, for production in biscuit porcelain at the manufactory. They also feature on a clock-model, known as L'Etude et la Philosophie for which the bronzier François Rémond (maître in 1774) produced a design commissioned by the marchand-mercier Dominique Daguerre. Plaster models of the figures preserved at Sèvres are illustrated by Guilhem Scherf et al, Louis-Simon Boizot, Exhibition catalogue, Paris, 2001, pp. 190-191, figs. 15 and 16.
