It is one of a number of works the artist made of scenes set in lunatic asylums, including Yard with Lunatics (1793–1794) and The Madhouse (1812–1813).^[1] These works were painted at a time when mad-houses were "holes in the social surface, small dumps into which the psychotic could be thrown without the smallest attempt to discover, classify, or treat the nature of their illness."^[2] Goya often feared for his own sanity, a fact which underscores these works with feelings of dread.
