Really good, modern coverage, with great sourcing and comparison among the original texts. I liked the chapter on historical development of the Greek myths. I would have appreciated more coverage of the Roman "editions", especially as I read this as Jeopardy prep, and overall more text and fewer pictures would have been just fine. The breakup of myth along thematic lines was sensible from a didactic perspective, but it doesn't work very perfectly from a reference perspective.
Anyway, probably my go-to now for Greek mythology, though hardly as portable as Hamilton.
