The pier-glass, conceived in the George II 'Modern' or French 'picturesque' fashion, has its flower-garlanded serpentined pilasters crowned by hermed busts of bacchic nymphs that derive from a French table pattern adapted by William Jones in his, Gentleman or Builder's Companion, 1739. Its pagoda-swept pediment crowned by Jupiter's eagle is featured in Matthias Lock's pattern book for carvers entitled, Six Sconces, 1744. A mirror with a similar eagle cresting was sold, anonymously, Christie's London, 30 November 2000, lot 101.
This mirror's unique frame is likely to have emanated from the same workshop as a related giltwood pier-glass in the collection of the Hon. Desmond Guiness at Leixlip Castle, Ireland (D. Guinness, Irish Houses and Castles, New York, 1971, p. 210).
