Diagram 14 is likely to be associated with Turner’s discussion, in Lecture 2 as Professor of Perspective at the Royal Academy, of the terminology of the discipline. It is headed ‘MOXON’ and claims to show the importance attached by the author to ‘ichnography’, but as Maurice Davies points out, so such diagram is to be found in Joseph Moxon’s Practical Perspective (1670).1 Apparently Turner’s own design, it illustrates a method due to the elder Thomas Malton; see his Compleat Treatise on Perspective in Theory and Paractice on the True Principles of Dr Brook Taylor, 1775, pp.48–9.
Davies 1994, p.299 note 41. See Turner, ‘Royal Academy Lectures’, circa 1807–38, Department of Western Manuscripts, British Library, London, ADD MS 46151 BL MS L folio 3. For earlier versions of material, see D folio 2 verso and E folio 4.
Peter Bower states that the sheet is Royal size Whatman paper made by William Balston and Finch and Thomas Robert Hollingworth, at Turkey Mill, Maidstone, Kent. He writes that ‘all the group of papers with 1794 dates in the watermark show considerable process dirt and poor formation’. He attributes the lack of quality control to James Whatman’s stroke and the change of ownership at the mill.1
