Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy, this diagram (possibly unfinished?) is related to two others (Tate D17106, D17107; Turner Bequest CXCV 135, 136) illustrating anamorphic perspective. This method produces a distorted image that appears in natural form only when viewed at a special angle or reflected from a curved mirror.
Peter Bower (unpublished notes)1 writes that the sheet is Super Royal size Whatman made by Finch and Thomas Robert Hollingworth, at Turkey Mill, Maidstone, Kent. This group ‘show both very good sheets as well as some outside, or retree, sheets where the “back” of the sheet, size spots and streaking, and formation shadows are visible’. Finberg incorrectly gives the watermark as ‘J. Whatman. Turkey Mill, 1823’.
