Xibalba

In Maya mythology Xibalba , roughly translated as "Place of fear", is the name of the underworld, ruled by Mayan spirits of disease and death. In the 16th-century Verapaz, the entrance to Xibalba was traditionally held to be a cave in the vicinity of Cobán, Guatemala. To some of the Quiché descendants of the Maya people living in the vicinity, the area is still associated with death. Cave systems in nearby Belize have also been referred to as the entrance to Xibalba. Another physical incarnation of the road to Xibalba as viewed by the Quiché peoples is the dark rift which is visible in the Milky Way.

Maya mythology refers to the pre-Columbian Maya civilization's extensive polytheistic religious beliefs. These beliefs had most likely been long-established by the time the earliest-known distinctively Maya monuments had been built and inscriptions depicting their deities recorded, considerably pre-dating the 1st millennium BC. Over the succeeding millennia this intricate and multi-faceted system of beliefs was extended, varying to a degree between regions and time periods, but maintaining also an inherited tradition and customary observances. The Maya shared many traditions and rituals with the other civilizations and cultures in the Mesoamerican region, both preceding and contemporary societies, and in general the entire region formed an interrelated mosaic of belief systems and conceptions on the nature of the world and human existence. However, the various Maya peoples over time developed a unique and continuous set of traditions which are particularly associated with their societies, and their achievements.
