Just a minor quibble: any historicising technique will depend on one’s knowledge of the setting. The further back in time the story is set, the less knowledge an author will have of the period in question. And the less the author knows, the fewer authentic background details he will be able to include in his story. So I wouldn’t want to lump together a character like Theseus and someone like Augustus. But thanks for the clarification.
