The Vision Serpent was a symbol of rebirth in Maya mythology, with origins going back to earlier Maya conceptions, lying at the center of the world as the Mayans conceived it. "It is in the center axis atop the World Tree. Essentially the World Tree and the Vision Serpent, representing the king, created the center axis which communicates between the spiritual and the earthly worlds or planes. It is through ritual that the king could bring the center axis into existence in the temples and create a doorway to the spiritual world, and with it power."
