"The cloud-conjured body of the Cosmic Monster is held up by the elegantly modeled figures of two of the Pawahtunob, also called bakabob, the world bearers who hold up the four corners of the sky...Here are the bearers of the east and the west, the path of the sun. Below their feet rest skulls, referring to the place of death and to the gaping skeletal maw of the Vision Serpent that opens into the Otherworld. The inscriptions along the tread between the skulls record the completion of 18-Rabbit's first k'atun of reign and also the dedication date of this temple. The inner sanctum of Temple 22 thus recalls the original acts of establishing sacred space at the time of the Creation."
