Christie's: Portrait of George Parker, 2nd Earl of Macclesfield, PRS, sold 8 December 2022. From the lot essay associated with that work: "One of the most successful painters working in Rome in the first half of the eighteenth century and celebrated throughout Europe, Conca specialised primarily in religious subjects and this is believed to be the only Grand Tour portrait that he undertook. It was commissioned to occupy a central spot in the Earls of Macclesfield ancestral home of Shirburn Castle and this is seemingly the first time it has been offered for sale since its conception. ... Conca's exceptionally elegant and grand portrait of Lord Parker portrays the young man in an imaginary setting in front of the Colosseum. His right hand rests on a map of Italy, his finger perhaps purposefully resting on Naples, the city that he and his mentor Wright enjoyed the most. The map sits on a contemporary giltwood and marble table which also holds a reduction of the Apollo Belvedere, an obvious reference to Parker's interest in ancient sculpture which was so clearly realised in his purchases of bronze reductions after the antique in Florence."
