Mayan cosmology
was a complex system of beliefs that explained the structure and dynamics of the universe
Astronomical observations and religious ideas were closely intertwined in Mayan cosmology, shaping their understanding of the world and their place in it
Three levels of universe
The Maya believed the universe consisted of three main levels: the heavens, the earth, and the underworld
The heavens were the realm of celestial bodies, deities, and ancestors
The earth was the domain of humans, animals, and plants, as well as the stage for the cyclical processes of life and death
The underworld was a dark and dangerous place, associated with death, decay, and the journey of the soul after death
World Tree concept
The World Tree, or Ceiba tree, was a central concept in Mayan cosmology, connecting the three levels of the universe
The tree's roots were believed to reach into the underworld, its trunk represented the earth, and its branches extended into the heavens
The World Tree was seen as a conduit for communication and travel between the realms, used by deities and shamans
The concept of the World Tree was often depicted in Mayan art and architecture, such as the Temple of the Cross at Palenque
Gods associated with astronomy
Several Mayan gods were closely associated with astronomical phenomena and the celestial realm
