"This amazing piece of ancient art once decorated the Mayan Temple at Tikal. It shows a man in a boat escaping from a land that is sinking into the ocean. A drowning man can be seen and a volcano erupts as a pyramid collapses into the water. Discovered and photographed by a German archeologist, it was taken to Berlin, but unfortuanately destroyed there during WW2"
However the story is clear enough already from what we know about Maya beliefs:
Earth, sky, underworld
Horizontally, the earth is conceived in various ways: as a square with its four directional or, perhaps, solstice points, or as a circle without such fixed points. The square earth is sometimes imagined as a maize field, the circular earth as a turtle floating on the waters. Each direction has its own tree, bird, deity, colour, and aspect, in the highlands also its own mountain. Vertically, the sky is divided into thirteen layers, and Classic period deities are sometimes linked to one of the thirteen skies. By analogy with the 'Nine-God' mentioned together with the 'Thirteen-God' in the Chilam Balam book of Chumayel, the underworld is often assumed to have consisted of nine layers. However, the Popol Vuh does not know such a ninefold division, and Classic period references to layers of the underworld have not been identified.
In the world's centre is a tree of life (the yaxche 'ceiba') that serves as a means of communication between the various spheres. In Palenque, the tree of life is a maize tree, just as the central world tree in the Borgia Codex; a curving bicephalic serpent hovers around it, which some believe to embody the ecliptic. The king was probably identified with the tree of the centre and is usually shown to carry the bicephalic serpent as a ceremonial bar.
In the Classic period, earth and sky are visualized as horizontally extended serpents and dragons (often bicephalic, more rarely feathered) which serve as vehicles for deities and ancestors, and make these appear from their maws. Other serpents, shown as vertically rising, seem to connect the various spheres, perhaps to transport the subterranean or terrestrial waters to the sky. Dragons combine the features of serpent, crocodile, and deer, and may show 'star' signs; they have been variously identified as the nocturnal sky and as the Milky Way.
World endings and beginnings
Within the framework of the post-Classic cycle of thirteen katuns (the so-called 'Short Count'), some of the Yucatec Books of Chilam Balam present a deluge myth describing the collapse of the sky, the subsequent flood, and the re-establishment of the world and its five world trees upon the cycle's conclusion and resumption. The Lightning deity (Bolon Dzacab), the divine carriers of sky and earth (the Bacabs), and the Earth Crocodile (Itzam Cab Ain) all have a role to play in this cosmic drama, to which a much earlier, hieroglyphic text from Palenque's Temple XIX seems to allude. The Quichean Popol Vuh does not mention the collapse of the sky and the establishment of the five trees, but focuses instead on a succession of previous mankinds, the last of which was destroyed by a flood.
For the Classic Mayas, the base date of the Long Count (4 Ahau 8 Cumku), following upon the completion of thirteen previous baktun eras, is thought to have been the focus of specific acts of creation. Through the figures of two so-called 'Paddler Gods', the mythology of the Maya maize god appears to have been involved. References to 4 Ahau 8 Cumku events are few in number (the most important one occurring on Quirigua stela C), seemingly incoherent, and hard to interpret. They include an obscure conclave of seven deities in the underworld (among whom the deity Bolonyokte') and a concept of 'three stones' usually taken to refer to a cosmic hearth.
