This pier-glass, embellished with Jupiter's eagle, nymph-headed herms and French dragons, is derived from 'sconce' patterns published by the carver Matthias Lock (d.1765) in his Six Sconces, 1744 (pls.3 and 4). Other closely related mirrors include a pier glass with matching table supplied by Lock to the 2nd Earl Houlett for the Tapestry Room at Hinton House, Somerset (c.1735) now in the Victoria and Albert Museum, London (illustrated in D. Fitz-Gerald, Georgian Furniture, 1969, pl.40); a pair supplied to Uppark, Sussex (illustrated Uppark: National Trust Guide Book, 1985, p.18); one sold from the collection of Gerald Hochschild, Sotheby's London, 1 December 1978, lot 39; three illustrated in G. Child, World Mirrors, 1990, pls. 112-114, and one sold Sotheby's New York, 16-17 April 1993, lot 456.

The motif of the hound chasing a dragon is derived from a design for a console table in Lock's Six Tables, 1746, pl.40 (illustrated in P. Ward-Jackson, English Furniture Designs of the Eighteenth Century, 1958, pl.50) which was, in turn, inspired by comtemporary French rococo designs notably an ornamental design by Hubert Gravelot (in the British Museum, London) showing a dog peering out from rocaille, after Jean-Baptiste Oudry's painting L'Arret du Cygne (see D. Fitz-Gerald, 'Gravelot and his Influence on English Furniture', Connoisseur, August 1969, pp.140-147). The hound notif appears in other mirrors attributed to Lock such as the Hinton House example and a pair of girandoles supplied to Henry Ingram, 7th Viscount Irwin for the Long Gallery at Temple Newsam, Leeds (see C. Gilbert, Furniture at Temple Newsam and Lotherton Hall, 1978, vol.II, pl.410).
