Abstract
There are certain ‘facts’ which every schoolboy knows. Every schoolboy knows, for instance, that at the Battle of Hastings King Harold was killed by a shot in his eye from an arrow; and Sir Frank Stenton's demonstration that he pretty certainly wasn't has done little to shake this conviction.1 Not every schoolboy, perhaps, but every undergraduate who studies the history of ancient Athens knows that Ephialtes was murdered. After all, that is what the books tell him. Thus in Meiggs/Bury we read that ‘Cimon's chief antagonist Ephialtes was murdered’; this is echoed by Forrest and Davies, to name just two authors of recent standard works. Hignett even knew the weapon the murderer used: ‘the dagger of the assassin removed him in the hour of his triumph’
