Bacab (Mayan pronunciation: [ɓaˈkaɓ]) is the generic Yucatec Maya name for the four prehispanic aged deities of the interior of the Earth and its water deposits.
The Bacabs played an important role in the cosmological upheaval associated with Katun 11 Ahau, when Oxlahuntiku 'Thirteen-god' was humbled by Bolontiku 'Nine-god'.
"[2] According to Francisco Hernández (quoted by Las Casas and Diego López de Cogolludo), the Bacab (apparently a unitary concept) was the son of the creator god, Itzamna, and of the goddess Ixchebelyax; he had once been humbled, killed, and revived.
Since they were Year Bearer patrons, and also because of their meteorological qualities, the Bacabs were important in divination ceremonies; they were approached with questions about crops, weather, or the health of bees (Landa).
In the rain almanacs of the Post-Classic Dresden Codex, the old man with the conch and the turtle is put on a par with Chaac.
