The artwork
A group portrait of Philip Yorke, 3rd Earl of Hardwicke (1757–1834), with his Governor, Colonel Wettstein, walking on the Janiculum with St. Peter’s beyond is catalogued as a work by Franciszek Smuglewicz (1745–1807).
The catalogue records the painting as the property of the Earl of Caledon, measuring 22 × 18 in. (55.9 × 45.6 cm). It notes that the portraits had descended in the Caledon family through Catherine Yorke, daughter of Philip Yorke, who married the 2nd Earl of Caledon. The painting was sold at Christie’s on 16 April 1982 as Lot 86.
The entry also cites Brinsley Ford, “Principal Antiquarian for the English Visitors to Rome”, Apollo, June 1974, p. 45, and records that Ford accepted the attribution to Smuglewicz. The present location of the painting has not been identified.
