Details 425 came from Portrait of a Man. An unknown sitter, by an unknown hand, dated around 100AD, this image was found on a mummy, resurrected by Flinders Petrie in 1888 at Arsinoe in Egypt. In other words, it's one of those famous, mysterious, strikingly individual mummy faces, eye-balling us down the centuries, about which little is known and much guessed. This man, who may have been an athlete or an initiate of an Isis cult, is sometimes named (wrongly, from another mummy in the same find) as Diogenes. Any answer along the right lines would do. The painting is in the British Museum.

The first three correct entries came from: M Pybus, Sheffield; J Denn, Chelmsford; and S Maeder, London W6
