As recognised by David Hill,1 this view is looking north across the Thames to Isleworth, with All Saints Church in its original form and the dome of the Pavilion marking the corner of Syon Park to the right. In the rather truncated space between them stood Syon Ferry House, which Turner had rented around 1805 as a base for exploring the river, as discussed in David Blayney Brown’s Introduction to the ‘Thames sketchbooks c.1804–14’ section of the present catalogue.2 For more on the Pavilion see entries by Brown (Tate D05494; Turner Bequest XC 3) and the present author (Tate D08163; Vaughan Bequest CXVIII I). What appear to be other Isleworth views with the Pavilion are on folios 33 verso and 36 verso (D17817, D17824).
Hill has written of the retrospective character of some of Turner’s Thames studies in the 1820s (see the sketchbook’s Introduction), when he still retained his self-designed house Sandycombe Lodge in nearby Twickenham.3 In this case the sketch is effectively a slighter reprise of a pen and ink view in the 1805 Studies for Pictures: Isleworth sketchbook (Tate D05528; Turner Bequest XC 27); Hill has noted other views of the house in the same sketchbook (D05602; Turner Bequest XC 72a) and in others in use in 1805: Hesperides (1) (Tate D05809; Turner Bequest XCIII 26a); Hesperides (2) (Tate D05904; Turner Bequest XCIV 43); and Thames, from Reading to Walton (Tate D05952; Turner Bequest XCV 48).4 For other London and Thames views in the present book, see under folio 2 recto (D17775).
