These drawings are among my favourites in the beautiful travelling exhibition catalogue The Stage of Drawing: Gesture and Act published in 2003 by The Tate in London. The book says little other than that they are from Album of Drawings, Mainly by Nathaniel Dance-Holland, date unknown.
I decided to investigate further, and Google instantly rewarded me with this picture (highly familiar to anyone from the colonies):
James Cook, by Nathaniel Dance-Holland, c.1775. It got me thinking: those of us who work in so-called creative industries but actually find release by doing our own creative thing outside of work might be part of a long history.
