Final answer:
El Tajin worshipped two main deities, the Rain or Storm God (Tlaloc) and the Feathered Serpent (Quetzalcoatl), indicating the city's strong cultural and religious influence in Mesoamerica.
Step-by-step explanation:
The two important cults that were based in El Tajin during the late classic-epiclassic period revolved around the worship of the Rain or Storm God and the Feathered Serpent. The Rain or Storm God, known as Tlaloc to the Aztecs, was associated with fertility, war, and sacrifice. Meanwhile, the Feathered Serpent, recognized as Kukulcan to the Maya and Quetzalcoatl to the Aztecs, was a deity symbolizing wisdom and was associated with the wind and the arts.
The influence of these cults extended beyond El Tajin, affecting other Mesoamerican societies such as the Aztecs, who would later adopt these deities into their own pantheon. This widespread veneration of deities demonstrates the strong cultural connections across Mesoamerican civilizations, including their practices of pyramid building, human sacrifice, and their shared maize-based agriculture.
