irtle's Manuscript Treatise on Watercolour, written no earlier than 1810,[note 6] is now in the Norwich Castle Museum. It was more a reference manual for his own use than a means of perpetuating his ideas for the future. Nothing written by Thirtle other than his Treatise is known to have survived. The treatise is an important document for art historians that provides documentary evidence of Thirtle's approach to his work as an artist. Allthorpe-Guyton dates it to no earlier than 1810, referring to pigments introduced early in the 19th century, such as purple and brown madder. It consists of an unorganised collection of technical instructions and observations, possibly made from paraphrases of published works such as Ackermann's New Drawing Book (1809). Thirtle's list of pigments is longer than Ackermann's and that given by William Henry Pyne, in his Rudiments of Landscape Drawing (1812). Both Pyne and Thirtle describe the use of indigo and provide schemes for colouring skies, buildin

It contains what Hemingway describes as "undertones of a classical aesthetic", also to be found in John Berney Crome's lecture Painting and Poetry.

Those watercolours where the pigment was used have deteriorated because the pigment faded to red when exposed to light. This characteristic of his paintings cannot be applied to them all, but it is sometimes assumed that Thirtle's works are all permanently ruined in this way. Equally, the use of indigo by other painters has meant that their wo
