young Gaius Marcius Coriolanus 423 BC?
Nobody knows what the Roman general Coriolanus really looked liked, but this photo http://www.sxc.hu/photo/956626 on Stock Xchange made me think of him.
Credit for the photo (entitled "Green Eyes
Portrait of a young semi punk boy") goes to Penny Matthews
Inspiration for the portrait goes to Steven Saylor, author of Roma: the novel of ancient Rome
