Prepared in connection with his lectures as Professor of Perspective at the Royal Academy, Turner’s diagram is based on an illustration from Samuel Cunn’s Euclid’s Elements of Geometry
(London 1759, Book 12, Plate 2). It illustrates Proposition 17, Book 12: ‘Problem. To describe a solid polyhedron, in the greater of two spheres, having the same centre, which shall not touch the superficies of the lesser sphere’.1
There are sketches of the Proposition in Turner’s lecture notes.2
Peter Bower states that the sheet is Colombier size Whatman paper made by William Balston, at Springfield Mill, Maidstone, Kent.1
Blank, save for an inscription by an unknown hand in pencil ‘11’ bottom left.
