There are four paintings of horsemen by Parrocel in the collection of similar dimensions and frame styles, which were hanging together in the Armory at Carlton House in 1816 (nos 484-7). This prompted John Robinson (Surveyor 1880-1901) to suggest, in an annotation to this Carlton House inventory, that they were ‘all of the same style & I think companions to Charles Prince of Nassau’. They are almost certainly two pairs brought together by George IV, the frame design of one probably then commissioned by him to match the other. This is one of the pair (with Charles, Prince of Nassau, RCIN 403390) bought by George IV and delivered to Carlton House in 7 June 1808. The portrait of Charles of Nassau may be dated to 1733, which provides a reasonable clue to the dating of this painting.
