Diagram 15 forms part of Turner’s discussion, in Lecture 2 as Professor of Perspective at the Royal Academy, of the terminology of perspective.1 The drawing illustrates terminology used by the mathematician Dr Brook Taylor (1685–1731) in his Linear Perspective: Or, A New Method of Representing Justly all Manner of Objects as They Appear to the Eye in all Situations (1715). However, Maurice Davies states that while the diagram lists terminology used by Taylor, there is no similar diagram in his treatise.2
The sheet conforms to others in the series identified by Peter Bower as 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
