(Antonia Forest fanficcers are tiresomely prone to the same thing. It's as if someone's manner of speaking has been set in concrete by the author and the characters will echo their teenaged selves twenty and thirty years later. Which, yanno, one would hope not.)
And I'm not convinced the whole of the acting troupe would take exception to the anachronistic mention of a clock in Julius Caesar and wonder why they weren't wearing historically appropriate bedsheet togas instead of their everyday wear. I should look this up, but did even the 18th century have a notion of anachronism? (Google. Wiki says the awareness and reaction to it dates from late 18C, but gives no citation.)
Meanwhile I need to finish The Younger Edda even if it makes my head spin. Norse/ Icelandic mythology is a mess, and constructing a coherent narrative from it seems rather like establishing the text of a Sumerian work from a bunch of shattered clay tablets. Probably one shouldn't even try, but just enjoy he moments of 'so *that's* where Tolkien got that name!'
