MEXICO CITY.- New hypotheses about the last stage and government of El Tajin civilization point out to a rule that was not exclusive of one person but of several, as announced in a conference series organized by the National Institute of Anthropology and History (INAH). According to studies performed at the Veracruz archaeological zone by Dr Arturo Pascual, from the National Autonomous University of Mexico (UNAM), El Tajin experimented in its last stage intense transformations in its government and ideology that were captured in its architecture and iconography. In this sense, near 800-850 AD, the ancient Mesoamerican city suffered a profound change in its government after the accession of a new group of a lineage linked to the figure of 13 Rabbit, depicted at the Edificio de las Columnas pillars. At the reliefs, characters with the same calendar name are represented at the western portico (dated between 800-850 AD)
