This is a fabulous resource for mythology fans. It folds out to one large family tree, making it that much easier to trace this convoluted genealogy. And when you're not using it, just tuck back into it's case and stick it on your bookshelf. All the primary gods are included, of course, but you'll also find minor and lesser-known gods. Plus, on the reverse, you'll find a genealogy of all those demigods like Herakles and Achilles. I always keep it available for a quick reference, and it's proven well-worth the money I paid for it.

Seems like a goofy little gimick of a book. To be fair, I've only glanced through it. Folds out like an accordion to "over seventeen feet in length", which makes it awkward to read. ( )
