This pair of mirrors closely relate to Irish mirrors of the period. They include a pair of mirrors supplied to Jenico, 10th Viscount Gormanston (1717-57) for the saloon at Gormanston Castle (The Knight of Glin and J. Peill, Irish Furniture, London, 2007, p. 84) which share the same cresting with a very similar incised latticework ground. Another closely related mirror was probably supplied to the Rt. Hon, William Connolly (d.1754) for Castletown House, Co. Kildare, Ireland, which hung in Lady Louisa’s Boudoir (ibid, p.223). The distinctive convex laurel leaf frieze is probably inspired by a drawing in William Jones’ 'The Gentleman's or Builders Companion, 1739, reproduced in lot 391. This drawing was the inspiration for many mirrors attributed to the Dublin firm of John and Francis Booker. A related pair of mirrors were sold from Cowdray, Christie’s, London, 23 May 2012, lot 35 (£63,650).
