Hubert Martinet is a fine but enigmatic clockmaker who was active both in London and Paris during the 1770's and 1780's. Although little is recorded of his specific activities it is known that he worked as both a horloger and a mercier and was probably a descendant of the Martinot clockmaking family the first of whom was Gilbert Martinot who is recorded as clockmaker to Henry III in 1572.Hubert Martinet is perhaps best known for his magnificent musical automaton elephant clock of 1774 which resides in the at Waddeston Manor. Martinet is also mentioned by Geoffrey de Bellaigue as a ‘marchand-bijoutier’ of another elephant clock formerly in the Rothschild collection; this example being a rare gilt bronze and Meissen porcelain example signed Gudin on the dial. In addition to these Bellaingne also mentions ‘Trois pendules d'Eléphant finies 5000 (livres)’ included in an inventory of Martinet's stock drawn up after bankruptcy on 7th June 1777. One of these, featuring a white porcelain elephant ridden by a black mahout and surmounted by a Turk, had previously belonged to the marquis de Béringhen. The current lot belongs to a series of around half a dozen similar clocks signed by Martinet which were probably made in Paris for retail in London. In addition to the example illustrated by Derek Roberts another was offered at Sotheby’s, London on Wednesday 18th December 1996 (lot 284). Both of these differ from the present clock in that they do not stand on a base applied with thermometers. Another larger version resides at the Musée des Arts décoratifs et du Design de Bordeaux, whilst two separate identical examples, each this time standing on a base and including twin thermometers, have been offered by Richard Redding Antiques Ltd, London.
