IN WHICH painting by which painter can you find this stray foot?

DETAILS 382 came from Leda and the Swan (1531-2) by Antonio Allegri, better known as Correggio. The picture is a fine example of that elusive quality, so admired by 18th-century connoisseurs, to which they gave the name "Correggiosity". It's in the Gemaldegalerie, Berlin-Dalhem.

The first three correct entries drawn from the hat were from: Geoffrey Walker of London SW1; Rosemary Rudall of Widcome, Bath; and Fiona Ward of Liverpool L1. Each will receive a bottle of champagne, as will this week's winners. Answers, on a postcard, to: DETAILS 384, IoS, 1 Canada Square, London E14 5DL.
