MEXICO CITY.- Recent explorations conducted by experts from the National Institute of Anthropology and History (INAH) point out that Plan de Ayutla Archaeological Site, in Chiapas, could have been the political center where the lineage that founded Bonampak originated,more than 1,400 years ago. This hypothesis is based on interpretation of inscriptions at different monuments. The archaeological zone that will be open to public before 2012, according to the compromise of President Felipe Calderon, could have been in Prehispanic times one of the legendary cities didentified by epigraphic as Sak T’zi or Ak’e. The first hypothesis regarding Plan de Ayutla identity points out that it might have been Sak T’zi, city that between 600 and 800 AD struggled with Maya metropolis of Tonina, Piedras Negras and Yaxchilan, informed archaeologist Luis Alberto Martos
