The Sleep-walker, James Gillray, 1795

Pitt, fast asleep, wearing only nightcap and night-shirt, walks down a staircase holding up a lighted candle in his right hand. On his right only are banisters, on his left the steps abut on a gulf indicated by the top of an arch supporting the stair; he is about to descend the first step, perilously near the left edge. Behind him, in a wall of heavy masonry, is an open door surmounted by a crown. A tall gothic window pierces the wall of the building. 1 november 1795 hand-coloured etching. Date: 1795.
