With the page turned horizontally, the view as identified by Cecilia Powell1 is east down the River Danube near the Strudel rapids to the left of the ruined Schloss Wörth (no longer extant) on the rocky Insel Wörth; for views on adjacent pages, see under folio 31 verso (D30059). Burg Werfenstein is outlined above the north bank in the distance towards the right; see also folios 34 recto–37 recto (D30064–D30070); fortuitously, Turner had recently made thumbnail sketches of existing prints of the subject; see folios 12 verso and 13 recto (D30025–D30026). There seems to be a small steamboat towards the left, and there is a written colour note in the shallows on the near side of the central island.
Discussing the artist’s Danube route between folios 31 verso–38 recto (D30059–D30072;2 like much of this sketchbook, apparently used in reverse of their present foliation), Powell has observed that within a brief stretch of two or three miles his ‘most intensive sequence of sketches, occupying fourteen pages, was made during the steamer’s cautious passage upstream from St Nikola to Grein, past the Wirbel and the Strudel’;3 these hazardous features, shown on old maps respectively east and west of Struden and nearby Burg Werfenstein, no longer exist following the elimination of associated rocks to improve navigation later in the nineteenth century. For the Wirbel whirlpool, see under folio 37 recto (D30070).
