Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy this diagram of a figure within a circle appears related to a group of drawings illustrating the ways in which geometry enters into art (Tate D17138, D40014, D17139; Turner Bequest CXCV 167, 168). See note to D17139 for their probable function as supplements to Lecture 1 and date after 1812. On the verso (D40014) is a complete diagram of the same figure, seen from the back, now enclosed in a square.
Peter Bower writes that the sheet is Elephant size Whatman paper made by William Balston, at Springfield Mill, Maidstone, Kent.
See Tate D40014.
