For the subject and related work see note to folio 3 of the sketchbook (D05494). This is one of various versions of the composition in the book, related to the painting of 1805–6 bought by the Earl of Egremont, known as The Thames at Weybridge (Tate T03872; displayed at Petworth House)1 but engraved as Isis for the Liber Studiorum. As Hill observes, this study is developed mainly from those on folios 29 and 30 (D05531, D05533). See also note to folio 30 verso (D05534).
