About
About Ceibal — Seibal Pyramid A-3 and Observatory
Bluff-top city 27 km east of Dos Pilas, excavated 1964–68 then by Inomata, famous for Structure A-3 atop A-II substructure (Late Preclassic cruciform E-Group) with four stairways each with stela (Stelae 1,7,10,11) and frontal altar — late Terminal Classic stelae show foreign Mexican facial style with non-Maya deities (Ehécatl). Inomata’s radiocarbon proves Ceibal had formal E-Group by 900 BCE, 1,000 years before Classic. Late florescence after 830 CE contradicts Petén collapse model.
Why it mattersEarliest dated ceremonial centre in Maya lowlands (900 BCE cruciform); Terminal Classic Mexican influence debate.
