Physicists, Biologists, and other scientists seek a "grand unifying theory" in their discipline to explain the big picture and fit disparate parts into a coherent whole. There may be a grand unifying theory linking the Book of Mormon with its ancient Mesoamerican setting.
G1 of the Palenque triad is likely the same deity as Central Mexico's Quetzalcoatl. George and David Stuart, Palenque Eternal City of the Maya (New York: Thames and Hudson, 2008) p. 212 and note 21.
G1 of the Palenque triad is likely the same demigod-deity as Hunahpu, the elder of the hero twins in the Popol Vuh. Floyd G. Lounsbury, "The Identities of the Mythological Figures in the Cross Goup Inscriptions of Palenque," Mesoweb, 1985; Linda Schildkraut, "The Hero Twins in Veracruz," FAMSI; Carolyn Tate, Yaxchilan: The Design of a Maya Ceremonial City (Austin: University of Texas Press, 1992).
G1 of the Palenque triad is likely a classic Maya instance of Jesus Christ in the Book of Mormon. See the article "Palenque."
If these relationships are true, they form a grand unifying theory that explains many things in ancient Mesoamerica and in the Book of Mormon.
For example, it explains why both Popol Vuh and Book of Mormon iconographic elements appear on Izapa Stela 25. See the article "Art and Iconography 2."
Ditto both Popol Vuh and Book of Mormon iconographic elements on Izapa Stela 5. See the article "Art and Iconography 4."
