Joseph Mallord William Turner 1775–1851
Folio 4 Verso:
Diagrams of a Cube and Squares Projected in Perspective, after Salomon de Caus circa 1809
D07362
Turner Bequest CVIII 4a
Pen and ink on white wove paper, 88 x 115 mm
Inscribed by Turner in ink (see main catalogue entry) at various points on and in relation to the diagrams
 
Accepted by the nation as part of the Turner Bequest 1856
The diagrams are labelled to the left of centre as ‘Du Cas | 1612’, and the squares and cube have various initial capital letters (‘A’, ‘B’, ‘C’, ‘D’, etc.) at their corners, with other letters (‘T’ and ‘X’) along a horizon line towards the top and at various vanishing points and intersections (‘L’, ‘M’, ‘N’, and ‘O’).
Maurice Davies has identified the notes and diagrams on folios 3 recto to 4 verso (D07359–D07361 and the present page) as taken from Salomon de Caus, La Perspective avec la raison des ombres et miroirs, London 1612 (see also folio 54 verso; D07450), in this case from unpaginated folio 42 verso. The same passages are translated from the French in Turner’s perspective lecture manuscripts, though apparently not in his hand.1
