Final answer:
In the 'Popol Vuh', the trinity consisting of Thunderbolt Hurricane, Newborn Thunderbolt, and Sudden Thunderbolt is known as the 'Heart of Sky'. This trinity is a central figure in K'iche' Maya creation myths, similar to Tlaloc and Quetzalcoatl in other Mesoamerican cultures.
Step-by-step explanation:
In the Mesoamerican text Popol Vuh, the trinity formed by Thunderbolt Hurricane, Newborn Thunderbolt, and Sudden Thunderbolt are collectively known as the Heart of Sky. These deities are central to the creation myth within the K'iche' Maya tradition. Their role is to participate in the creation of the world and humans, and they contribute to various natural phenomena, such as storms and tempests, that are pivotal to the agricultural lifeways of the Maya people. The concept of a triad of storm-related gods reflects a broader theme in Mesoamerican religion where similar deities are revered across different cultures. The Mexica (Aztecs) recognized Tlaloc, the rain/storm god, and Quetzalcoatl, the feathered serpent deity, who play comparable roles to the Maya gods in the facilitation of agriculture through rain and fertility.
