Drawn with the sketchbook inverted and continued on folio 33 (D10641) this study is very badly rubbed, especially in this half of the composition. However Finberg was surely right to link it to The Decline of the Carthaginian Empire (Tate N00499)1 exhibited at the Royal Academy in 1817. The composition is especially close in D10641, including the group of trees alongside the harbour at the centre of the picture and the round building on the left. Ideas for a classical arcade and buildings on a hill running from folio 30 verso to the recto of the present leaf (D10636–D10639) are probably also related, though more distantly.
