This portrait medallion is likely to have been carved by the itinerant French ivory sculptor, Jean Cavalier or by a sculptor working in his circle. It may be related to an engraved image. Although it differs slightly in size, it is likely to be a pendant to the relief of Queen Mary II (Mus. no. A.126-1956). Jean Cavalier (1650/60-1698/9), a Hugenot, was a native of France, and perhaps a Protestant. He travelled extensively, working as a wax modeller and ivory sculptor, and specialising in portrait medallions. In the 1682/3 he went to London, where he stayed until 1686; he then went to Trier, perhaps Stuttgart, Düsseldorf, Hamburg, Hannover, Kassel, and in 1689 to Vienna, Munich and perhaps Dresden. By 1690 he was back in London, where he carved pictures of the King and Queen and was given the passport as the 'King's medallist'. He was then at the Danish Court in 1691/3, and from 1694/5-7 in Stockholm, from whence he and his brother Denis, also a sculptor, journeyed as ambassadors on behalf of Sweden to Russia and Persia, where they both died. Cavalier was the most accomplished ivory-carver working in late Stuart England until the arrival of David Le Marchand around 1700.
