The design for this clock, traditionally attributed to the fondeur François Vion and composed by Jean-Claude-Thomas Duplessis, is now in the Metropolitan Museum of Art, New York and illustrated in M. Meyers, French Architectural and Ornament Drawings of the Eighteenth Century, New York, 1992, p. 203. A clock of virtually identical model was delivered by the clockmaker Robin for the Comte de Provence at the Palais de Luxembourg circa 1782-3 and subsequently sold from French and Company, Christie's New York, 24 November 1998. Interestingly, the French and Company clock case was attributed by J-D. Augarde to the fondeur Lemoyne, who was elected maître-fondeur-ciseleur on 28th March 1772 (J.D. Augarde, Les Ouvriers du Temps, Geneva 1996, 1996, p. 262, fig. 206). Augarde (op. cit.) also states that Louis XVI, Marie-Antoinette and Mesdames Victoire and Adélaïde owned similar clocks. Another clock, identical but with its original Bacchic mask to the frieze, almost certainly acquired by Baron Mayer Amschel de Rothschild, was sold from the collection of the 7th Earl of Rosebery, Mentmore Towers, Buckinghamshire, Sotheby's House Sale, 18 May 1977, lot 67. Three further related examples all sold anonymously, Christie's New York, 26 October 2001, lot 226, 22 May 2002, lot 315, and 2 November 2000, lot 157.
