The two related views here were made with the page turned horizontally. As suggested by Finberg1 and confirmed by Cecilia Powell,2 each they show the ruins of Burg Rolandseck, featuring the Rolandsbogen arch, high on the west bank of the Rhine on the left, the former nunnery on Nonnenwerth island, and the Drachenfels hill further off on the opposite bank, looking north down the river. The upper variant was evidently made in the course of passing the nunnery via the main channel, between Nonnenwerth and its eastern counterpart, Grafenwerth.
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.
