PUBLIC RITUAL and INTERREGIONAL INTERACTIONS: EXCAVATIONS of the CENTRAL PLAZA of GROUP A, CEIBAL

The probable E-Group assemblage was a primary focus of our investigation at the lowland Maya center of Ceibal. Tunnel excavation into Structure A-20 (the western structure of this complex) demonstrated that the Ceibal residents built the earliest version (Structure Ajaw) by carving natural marl around 950 b.c. The earliest version of the eastern platform (Structure Xa'an) was also made at the same time out of the natural marl layer. Through a series of renovations, the western structure grew into a pyramidal shape, and later versions of the eastern platform were moved further to the east. In addition, excavations revealed numerous caches, many with greenstone axes, along the center line of the E-Group assemblage. These results show that a formal ceremonial complex was established at the beginning of occupation at Ceibal, and its construction and public events held there played an important role in the creation of a new community.
