One of the highlights of Lecture 2, given by Turner as Professor of Perspective at the Royal Academy, is his survey of historical techniques for drawing a cube in perspective. He begins with Diagram 27, demonstrating a method proposed by Jean Pélerin (?1435–40; died 1524), a French architect, sculptor and cleric who wrote under the name ‘Viator’. In De Artificiali Perspectiva (1505) – the first treatise on perspective printed in Europe – Pélerin made the distance point method the basis of his system. Turner stated that it was ‘the earliest treatise I have met with’.1 While researching his lecture, Turner copied one of Pélerin’s diagrams (1505, pl.1, centre diagram) into his Perspective sketchbook three times, but, according to Maurice Davies, on each occasion he omitted the part that shows the square itself (Tate D07396; Turner Bequest CVIII 27 recto, also D07429; Turner Bequest CVIII 44).2 In a preliminary version of the lecture, Turner provides a short description of Pélerin’s approach.3 In another early version, of Lecture 3, Turner supplies a new description of the method which corresponds to what is illustrated in Diagram 27 but deviates significantly from Pélerin.4 Because the manuscript used for lecturing does not include this new description and only refers to Pélerin in passing, Davies concludes that ‘it is unlikely that [Diagram 27] was included in the lecture that Turner delivered in 1811’.5

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
