The outline sketch on this page is so slight that British Museum curator A.M. Hind saw fit to write his memorandum about the rebinding of the book across it. The executors of Turner’s estate had already occupied the available free space on the page, having little choice as to where to inscribe their endorsement, since the other end papers are taken up with closely written lists of places; see inside the front cover and the recto of the front flyleaf (D40752, D41434). It is nevertheless possible to confirm that the outline, which appears to have been made from a moving vehicle or horseback, does indeed represent Dynevor Castle, in the Tywi valley west of Llandeilo.
The reason for Turner’s double inscription, in two distinct scripts, is not obvious: perhaps one was made while moving, the other when he was stationary. Since this seems to be the only view of Dynevor in the sketchbook, the fact that it has given the book its name is somewhat anomalous. Dynevor is studied in more detail in the Hereford Court sketchbook (Tate D01272, D01275, D01276; Turner Bequest XXXVIII 22, 24a, 25), while in the present book drawings of neighbouring locations in the Tywi valley, at Llandeilo and Drwslwyn for example, are on folios 53 verso–54 recto and 54 verso–55 recto (D01548–D01551; Turner Bequest XL 51a–52, 52a–53).
