The inscription ‘Le Fort de St. Rock, Valley de Aoust’ recorded by Finberg as attached to this drawing is no longer present and might instead have belonged to the coloured study of Fort Roch (Fitzwilliam Museum Cambridge) if, as has usually been thought, it originated in this sketchbook.1 Both the Fitzwilliam study and the finished version made for Walter Fawkes2 show scenery much more dramatic than the relatively shallow, pastoral valley depicted here.
Andrew Wilton, The Life and Work of J.M.W. Turner, Fribourg 1979, p.341 no.360, as ‘Fortified pass, Val d’Aosta’. Regarding the origins of the Fitzwilliam drawing, however, it must be noted that Peter Bower has recognised that two other drawings formerly thought to have come from this sketchbook are actually on different paper; see Introduction to the sketchbook.
