Catalogue entry

Made in connection with Turner’s lectures as Professor of Perspective at the Royal Academy, this diagram illustrating parallel lines and lines at various angles may have been used for his later lectures on geometry.
Technical notes:
Peter Bower (unpublished notes)1 writes that the sheet is Double Elephant size Whatman paper made by William Balston and Finch and Thomas Robert Hollingworth, at Turkey Mill, Maidstone, Kent. Bower notes that ‘all of the group of papers with 1794 dates in the watermark show considerable process dirt and poor formation. Perhaps this lack of quality control at Turkey Mill was the result of the disruption caused by James Whatman’s stroke and the change of ownership at the mill’.
Notes in Tate catalogue files.
Blank, save for an inscription by an unknown hand in pencil ‘1’ bottom left.
