The drawing was made with the page turned horizontally. As suggested by Finberg1 and confirmed by Cecilia Powell,2 it shows Rolandseck, with the ruins of the castle high above on the left, Nonnenwerth island in the Rhine, and the Drachenfels hill, also crowned by ruins, on the right, looking north down the river.
Powell has noted that Turner neared the end of this tour following ‘the familiar route of the Rhine between Mainz and Cologne. He almost certainly travelled by steamer, ... sketching most of the well-known sights perfunctorily as he passed.’3 Given that this sketchbook was used in reverse of its subsequent foliation, she has specified the overall range of this phase as ‘TB CCCIII 68v–20v; 11r’,4 indicating folios 12 recto and 21 verso–69 verso (D30479, D30497–D30592; Turner Bequest CCCIII 20a–68a); see this book’s Introduction for the full itinerary of this part of the journey.
