This is probably a view of Lake Brienz towards Ringgenberg Castle, similar to that on folio 46 verso of this sketchbook (D04791). Combined, these two views may have been the basis of a chalk elaboration in the Grenoble series (Tate D04543; Turner Bequest LXXIV 50), which in turn was translated into a colour study, about 1809 (Tate D04896; Turner Bequest LXXX C). This last served for the finished watercolour made around the same time for Thomas Wright (Bowood Collection).1
