(Courtauld Gallery, London, until 25 May 2015)
A man slumps at a table, his head buried in his arms. As he dreams, the dark creatures of his imagination rise out of the shadows behind him: a lynx, which looks up with wide eyes; bats, flocking in the darkness, and owls which mob the sleeping figure with their wings and steal his artist’s tools. This etching, made in 1799, forms part of Goya’s print series Los Caprichos and was originally conceived as an allegorical self-portrait. Its title is The Sleep of Reason Produces Monsters. For all of mankind’s pretensions to reason and rationality in this Enlightened age, Goya seems to say, we only have to sleep for our primal nightmares to come crawling out of the woodwork.
