Your quest begins at the El Tajín Archaeological Zone, a major Totonac site built between 900 and 1200 AD, discovered in 1785 by Bernardo de Monteagudo. This vast 14-hectare complex, home to over 150 structures including 20 ballcourts, was a ceremonial center of paramount importance. The astronomical alignments of its buildings, particularly for the solar equinoxes, immediately immerse you in Totonac cosmology. Your first task will be to decipher the symbols left by the builders, whose wisdom still governs the cycles of time in Veracruz.
Continue towards the Pyramid of the Niches, the flagship edifice of the site. Standing 18 meters high and built around 1000 AD, it is unique for its 365 niches, each symbolizing a day of the Totonac solar year. Carefully restored by Alfonso Caso between 1934 and 1946, this 7-terraced pyramid reveals its cosmic role: its central staircase is precisely oriented towards the sunrise at the equinoxes. Traces of resin and copal found in the niches suggest they contained ritual offerings, crucial clues for your investigation into the sacred practices of central Mexico.
The South Ballcourt (Juego de Pelota Sur), one of the site's 17 ballcourts, awaits you next. Dating from the 11th century, this 126m long by 30m wide stadium, with its 8m high walls, featured carved panels depicting deities. The ritual game, involving a rubber ball, symbolized life and death in Mesoamerican mythology. Excavations in 1934 unearthed sacrificial altars at its ends, proving the spiritual intensity of these confrontations. These locations are essential to understanding Totonac rituals and their connection to the celestial cycles you are studying at El Tajín.
Your journey then takes you to Tajín Chico, an elite complex of 15 structures spanning 2 hectares, dated between 1100 and 1200 AD. This former residential quarter of the Totonac nobility, with its temples, altars, and residences, had restricted access through a monumental gate. The bas-reliefs adorning its buildings narrate cosmogonic myths, foundational stories of the Totonac world. Excavations conducted by INAH since 1993 have revealed tombs with jade and obsidian offerings, treasures that shed light on the life and beliefs of the elite of this civilization in central Veracruz.
Finally, at the Pyramid of the Morgue (Pirámide de la Morgue), named after the discovery of a mummified skeleton in 1944, you conclude your exploration. Built around 1100 AD, this 6-terraced pyramid, 13m high, housed a temple with carved skulls and death symbols. The mummy, carbon-dated to around 1200 AD, wore shell ornaments, offering insight into funerary practices. As you complete your investigation in Veracruz, you will have unraveled the threads of time, from astronomical alignments to sacred rituals, and understood how the Totonac culture inscribed its cosmic vision into the stone of El Tajín, a UNESCO World Heritage site since 1992, whose Voladores de Papantla, inscribed by UNESCO in 2009, continue the tradition.
