NOTE : The design of the case of this clock is generally attributed to André-Charles Boulle, (1642-1732), who was appointed cabinet maker to Louis XIV in 1672, (see fig.1.). Referred to by Tardy as a 'helmet' clock, it is also known as a 'pendule aux harpies'. A rare model, the known examples all differ slightly in the composition of the mounts and inlay. Sometimes supplied on a pedestal, another example on a similar stand was sold Sotheby's, Mentmore, 18th May, 1977, Lot 5.

Isaac Thuret, (circa 1630-1706), a great French clockmaker. After serving his apprenticeship he was received as a master clockmaker at Faubourg St. Germain-des-Prés in 1662 and in Paris before 1675. He held a number of Royal appointments and was an ingenious and inventive maker. His finest clocks were housed in cases supplied by André-Charles Boulle.
