Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy, this ground plan of an unidentified building appears to be related to another (Tate D17023; Turner Bequest CXCV 53). These diagrams are marked ‘No 1’ and ‘N 2’, and may be related to a one depicting a vaulted arch in perspective and marked ‘No 3’ (Tate D17120; Turner Bequest CXCV 149), which Judy Egerton has linked to an earlier diagram of a prison interior based on an etching by Giovanni Battista Piranesi (Tate D17099; Turner Bequest CXCV 128; see also Tate D17090, D17091; Turner Bequest CXCV 120, 121).1 If this is the case, the first two diagrams in the later series may be plans of the prison and all three might have supplemented lecture material on the production of shadows.2

Peter Bower (unpublished notes)1 writes that the sheet is royal size Whatman paper made by William Balston and Finch and Thomas Robert Hollingworth, at Turkey Mill, Maidstone, Kent. Bower notes that ‘all of the group of papers with 1794 dates in the watermark show considerable process of dirt and poor formation. Perhaps this lack of quality control at Turkey Mill was the result of the disruption caused by James Whatman’s stroke and the change of ownership at the mill’. He also writes that the paper used for this diagram ‘can be identified as having made on the same mould as [Diagram 13]’ (Tate D17027; Turner Bequest CXCV 57).
