Prepared in connection with his lectures as Professor of Perspective at the Royal Academy, Turner’s diagram is based on a plate from Dr Brook Taylor’s Method of Perspective Made Easy; both in Theory and Practice: in Two Books (London 1768, vol.II, pl.IV, fig.5) by John Joshua Kirby (1716–74).1 According to Maurice Davies, it corresponds to a section of Turner lecture manuscript containing notes on methods, primarily based on Kirby, and used to support other lecture material when further examples of perspective were required.2

Technical notes:
Peter Bower writes that the sheet is Imperial size Whatman paper made by Finch and Thomas Robert Hollingworth, at Turkey Mill, Kent. Bower notes: ‘This paper is very heavily sized and bears some relationship to the Parchment Substitute papers produced by various hand made papermakers in the nineteenth century (and into the twentieth) for legal documents. Sometimes papermakers don’t quite keep up their quality control. In the case of this particular sheet [and about nine others from the same batch also used by Turner for his diagrams] the mould has been left, probably overnight, without being cleaned and small amounts of pulp have dried between the support bars under the mould cover and the two layers of woven wire making up the cover. This affects the drainage of the sheet during formation and leaves a clear impression of the mould’s actual structure and construction.’1
