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 of the pairs probably then commissioned by him to match the other. The first pair (403389-90) was bought in 1808; this pair (with RCIN 400594) was first mentioned in 1816 (see above).
