Joseph Mallord William Turner 1775–1851
Lecture Diagram: Figure, with Outstretched Arms and Legs, Enclosed within a Square: Back View circa 1812–28
Pencil and watercolour on white wove paper, 588 x 714 mm
Watermarked ‘J WHATMAN | 1812’
Inscribed by an unknown hand in pencil ‘160’ bottom left
Accepted by the nation as part of the Turner Bequest 1856
Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy, this diagram of a figure within a square is on the verso of a diagram of the same figure shown from the front and enclosed within a circle (D17137
; Turner Bequest CXCV 166). Both appear related to a group of drawings illustrating the ways in which geometry enters into art; see also Tate D17138
; Turner Bequest CXCV 167, 168 and especially notes to the last of these for their likely production after 1812 to supplement Turner’s discussion of the topic in Lecture 1.
