"Fall of Atlantis" by Robert Stacy-Judd, 1936. Fictitious, but I like the style and the depiction of Mayan rowboats! Also a pretty good article on the Hidden World of the Maritime Maya. As much as the evidence doesn't exist in great quanties, it is believed that the Mayans carried out thriving maritime trade throughout the nearby coasts of the "New World." Also 500th post on the Mayan Art thread!
