Worcester City Art Gallery and Museum (Worcester, UK): Turner: Ambitions in Architecture and the Art of Perspective
Turner prepared Diagram 35 for Lecture 3 as Professor of Perspective at the Royal Academy. It illustrates how to draw a simple double cube or rectangular object at 45 degrees to the picture plane. See Diagram 36 (Tate D17050, Turner Bequest CXCV 80) for the same double cube developed into a house with basic architectural features. Turner attributes the method to Samuel Wale (?1721–1786), English draughtsman, painter and the Academy’s first Professor of Perspective (1768–86). As Wale is not known to have written any works on perspective, Turner may have had access to unpublished material.1 Maurice Davies notes that Turner omits many essential details in his description of the method, particularly in regard to locating the vanishing points or determining the correct height of the object,2 and that the diagram is also inaccurate because Turner has failed to position the vanishing points correctly. This is one of most important steps in any perspective construction, and essential for determining both the plan in perspective and the top edges of the double cube. Davies believes this may not have concerned Turner who probably felt that ‘strictly accurate perspective is not essential to a successful work of art’.3

Peter Bower states that the sheet is Double Elephant size Whatman paper made by William Balston, at Springfield Mill, Maidstone, Kent. The largest group within the perspective drawings, this batch of paper shows a ‘grid-like series of shadows that can be seen within the sheet in transmitted light. This appears to have been caused by a trial method of supporting the woven wire mould cover on the mould’. Because this is the only batch he has seen with such a feature, Bower believes that ‘it may have been tried on one pair of moulds and for some reason never tried again’. He also writes that it is ‘not the best Whatman paper by any means; the weight of this group is also very variable and the moulds have not been kept clean during use’.1
