This view is similar to that shown on Tate D28617; Turner Bequest CCXCI 41a, and depicts the castle and mountains of the Rolandseck and Drachenfels with the Nonnenwerth (or ‘Nun’s Island) in the middle of the Rhine between them.
Turner recorded the Rolandseck, Drachenfels and Nonnenwerth on a number of occasions in his tours of 1817, 1824, 1833 and 1840; see, for example, Tate D12572, D12868, D12887, D19840, D30500, D30505–D30508; Turner Bequest CLIX 30a, CLX 85a, CLXI 3, CCXVI 145, CCCIII 22, 24a–26. Other representations in this sketchbook are found in Tate D28622–D28623; Turner Bequest CCXCI 44–44a. There is also a vignette design entitled The Brave Roland of c.1835 produced to illustrate Campbell’s Poetical Works. For Edward Goodall’s engraved impression of it, published in 1837, see Tate Impression T04779.
