I stated this on the day before we left, while I was packing my bag:
One of the things I really enjoyed is reading a book about Mayan mythology and their gods, It's really cool. it seems like the Mayan didn't like their gods very much and sort of treated them like a pesky landlord to whom you have to pay homage and scarify people and animals, but that god's as such don't merit respect or devotion.
One of the exception to the rule was Quatzo-Coatel, who was actually a man who got reborn as a god rather then a born god.
The other myth I really like is about Ix-Chel, the godess of rainbows, childbirth and all thing women related, who was stuck by lightning and then got to be dead for half of the Mayan year and covered in dragonflies who sang her back to life.
One and a half more page to go, and the book is really to take off!
