It's terrifying! Unspeakably terrifying! More terrifying than anything I'd ever seen before!

While discussing (dissecting? vivisecting?) Robert Graves' famous The Greek Myths, Nick Lowe snarls that "[i]n so far as his metamyth has any merit, it is as a posher cousin of H. P. Lovecraft’s Cthulhu mythos: an elaborate shared-world fantasy prehistory for later writers to colonize, as most novelists of Mycenaean Greece have ended up doing one way or another."  Are those tentacles waving from my bookshelves?
