Jean-Simon Bourdier, maître horloger in 1787.
The clock pattern is likely to have been inspired by the engraving of 'Apollo' on Mt Helicon (illustrated in C.N. Cochin, Iconologie par Figures, Paris, 1757, book 1, no.27). An ormolu-mounted Sèvres porcelain 'lyre' clock, dated 1787 was supplied for the Salon des Jeux at Versailles (see P. Verlet, Les Bronzes Dorés Français du XVIIIeme Siècle, Paris, 1987, p.459).
Etienne Gobin, known as Dubuisson (died circa 1822), watch and clock enameller, worked at Chantilly and Sèvres as a flower painter. He is later recorded in the Rue de la Huchette in the 1790s before moving to Rue de la Calandre around 1812. Duboisson's name has been recorded on a number of Sèvres clocks of this form.
