The lamp's 'Vestal' figure corresponds to that of a set with life-size models supplied in 1800 by the porcelain modeller Francis Hardenberg (d.1832) of Hardenberg and Co., Petrification Manufacturers, 19 Mount Street for Burghley House, Stamford (Country House Lighting, Temple Newsam Country House Studies, 1992, fig. 118). The early 19th Century stamp of the plaster figure maker Robert Shout is found on a lamp of this model sold anonymously, in these Rooms, 21 July 1988, lot 22. A bill-head dated 1806 advertised his manufactory and spacious show rooms at 18 High Holborn as having 'a large sortment of figures and tripods for holding lamps or candles of various patterns and dimensions, fitted up in a new and fashionable style: suitably adapted for walls and staircases, pier tables, sideboards, Chimney pieces etc. Likewise several hundreds of figures .... from the Antique, and likenesses of distinguished personages made to imitate real bronze' (A. Coleridge, 'The 3rd and 4th Dukes of Atholl and the firm of Chipchase', The Connoisseur, February 1966, p. 101 and T. Clifford, 'The plaster shops of the rococo and neo-classical era in Britain', Journal of the History of Collections, 1992, vol. IV, no. 1, pp. 63-64).
