COMPETITION: DETAILS NO 373

IN WHICH painting by which painter can you find this great leg?

DETAILS 371came from Poussin's staggering Landscape with Diana and Orion (1658). The blinded giant, Orion, is being guided through the terrain - by the man on his shoulders - towards the rising sun, whose rays will heal his sight. The picture is in Moma, New York. The first three correct answers for Details 371 came from: Margaret M Sibley of Bingham, Nottingham; Jessica Palmer of Swansea, South Wales; and Yusef Azad of London SW2. Each will receive a bottle of champagne, as will this week's winners. Answers, on a postcard (to arrive by Wed 18 Feb), to: DETAILS 373, IoS, 1 Canada Square, London E14 5DL.
