Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy, this diagram is based on figures 55 and 56 from John Hamilton’s Stereography; or a Complete Body of Perspective in all its Branches (1738, pl.18) where they illustrate ‘Properties of lines harmonically divided.’ Maurice Davies writes that the diagram was left unfinished. For a preliminary sketch by Turner, also after Hamilton, see the Perspective Sketchbook (Tate D07383; Turner Bequest CVIII 17).
Technical ntes:
Peter Bower (unpublished notes)1 writes that the sheet is Super Royal size Whatman paper made by William Balston and Finch and Thomas Robert Hollingworth, at Turkey Mill, Maidstone, Kent. Bower adds that ‘all the sheets in this batch have some streaking across the sheet, probably from a fault in the sizing’.
