These oval 'medallion' frames, carved with 'antique' flutes between husk-festoon and egg-and-dart borders and their Grecian palmette-framed crest supporting sacred urns, relate to the 'Ovals' designed by Thomas Chippendale (d. 1779) for Lady Winn's apartments at Nostell Priory, Yorkshire, at a cost of #50, and invoiced in 1767 (C. Gilbert, The Life and Work of Thomas Chippendale, London, 1978, fig. 282). However these lyre-shaped palmette frames, comprising tied acanthus-scrolls deriving from antique ceiling enrichments (illustrated in William Chambers' Treatise of Civil Architecture, 1757, pl. 33), are executed in a less florid manner; while the acanthus-bud finial, shown at the base of Chippendale's design (Gilbert, op. cit., fig. 281) is here replaced by Venus' scallop-shell. The scallop-shell and a closely related cresting appear on a rectangular mirror (Gilbert op. cit., fig. 272) which may have been commissioned for the same room at Harewood House. Like the Nostell 'Ovals' they were designed to correspond with Robert Adam's neo-classical interior decoration
