Well, the only one I've really had a chance to read are Greco-Roman mythology stories. And I do find them pretty entertaining. All the old classics, like the Odyssey, the Aeneid, the Iliad, Ovid's Metamorposes. Odyssey is probably my favourite though, simly because it's actually well written and holds up by modern standards
I do Classical Civilisation in school, so I have to learn alot of this stuff.
