Drawn with the sketchbook inverted. As Hill observes, the view is from near the head of Romney Lock Island, looking north-north-west towards Eton. Folio 135 verso (D06356) looks from a similar spot in the opposite direction towards Windsor Castle. Here, the weir is seen on the left. Of Eton College Chapel, Hill notes that Turner ‘fudged’ its east end and ‘forgot the roof altogether’.1 Nevertheless, the sketch served as the basis of The Thames at Eton (Tate T03873; displayed at Petworth House),2 exhibited at Turner’s Gallery in 1808. In the picture, Turner also generalised the east end and omitted the roof while moving the whole building further to the left and emphasising the river and its banks below the weir.
