Robert Robin, maître in 1767 and appointed horloger du Roi in 1785.
Astrology is represented on this mantel clock by the figure of Urania with a collection of astronomical instruments and charts scattered around her. The model is loosely based on a drawing by Jean-Louis Prieur, dated around 1766, for a clock intended for the Royal Palace in Warsaw. Pierre-Antoine Foullet included a similar drawing for a mantel clock with Urania in his Livre de desseins, which was described as Pièce de Bureau and priced at 341 Livres.
A closely related model of this clock attributed to Robert and Jean-Baptiste Osmond in the Landesmuseum, Stuttgart is illustrated in H.Ottomeyer, P.Pröschel et al., Vergoldete Bronzen, Munich, 1986, vol.I, p.166, fig.3.4.3; while another clock with Urania, also signed by Robin, based slightly closer on Foullet's drawing, was sold anonymously, Christie's Monaco, 13 December 1998, lot 344 (FF 69,000).
