Turner used the main part of this folded card cover (see the technical notes below) for a single slight view along a broad river, with a bridge with at least three arches in the middle distance, perhaps a tower or trees in the left foreground, and what seems to be an urban skyline with towers on the opposite bank. At the top right, within the folded portion, is a thumbnail sketch with a gabled building at the end of a bridge, and jagged mountains beyond; this is possibly a detail or variant of the left-hand part of the larger view.
The treatment has the hallmarks of a ‘carriage sketch’, snatched on the move, with its clarity further hindered by the rough support. Over half of the pages in this book comprise relatively slight sketches from Turner’s homeward route north through the valleys of the Alps via Trento, Bolzano (Bozen) and Innsbruck. As set out in the Introduction, although his overall itinerary is clear from many identified subjects, they were are not drawn in a single sequence, making the scenes around them difficult to place.
