Well, yeah, there are obviously different versions - that Wikipedia entry had barely anything in it with which I was familiar. Still, I have at least three compilations of Greek myths in my bookshelf, and most of the time they agree with one another, so while I'm not saying that Wikipedia is WRONG (although I've come across a number of entries in it which are more than a little sketchy), I think I prefer to trust my version. Mind you, I'm not saying that there wasn't a Golden Age, Silver Age, etc. - it's just that the placement of them tends to differ from source to source.
