These wall-lights, with lion's masks issuing acanthus-wrapped arms beneath a classical urn with oak-wreath swags, were conceived in the fashionable goût grec of the late 1760s and early 1770s. Similar examples are illustrated in S. Eriksen, Early Neo-Classicism in France, London, 1974, ills. 210 and 216, and those in the Residenz in Munich, in H. Ottomeyer, P. Pröschel, et.al., Vergoldete Bronzen, Munich, 1986, vol. I, p. 186, ill. 3.9.1. A related pair, with ram's rather than lion's heads, was sold from the Blackwell collections, Christie's, London, 14 December 2000, lot 66 (£ 14,687).
