Hieroglyphically, the head of God K can substitute for the syllable kʼa in kʼawiil, a word possibly meaning 'powerful one', and attested as a generic deity title in Yucatec documents.
This substitution has given rise to the idea that, inversely, the title kʼawiil as a whole should be considered a name specifically referring to God K.[4] Lightning plays a crucial role in tales dealing with the creation of the world and its preparation for the advent of mankind.
In the cosmogony of the Popol Vuh, three Lightning deities identified with the 'Heart of the Sky' (among whom Huraqan 'One-Leg') create the earth out of the primordial sea, and populate it with animals.
Bolon Dzacab plays an important, if not very clear role in the cosmogonical myth related in the Book of Chilam Balam of Chumayel, where he is identified with wrapped-up seeds.
Kʼawiil also figures in an enigmatic Classic scene known only from ceramics (see fig.2), showing an aged ancestor or deity emerging from the serpentine foot of the lightning god, apparently to mate with a nude young woman of decidedly aristocratic allure entwined by the serpent.
The illustrated k'atun cycle of the Paris Codex suggests that the presentation of the head of Kʼawiil – perhaps holding the promise of 'Innumerable Generations' – was part of the king's ritual inauguration and accession to the throne.
[1] Holding k'awiil was a sign not only of the king's abilities in war and politics but also his power to bring agricultural abundance (particularly with regard to maize and cacao seeds).
