Zeus was the dominant God in the sanctuary of Olympia. Evidence that the site was connected with the worship of Zeus from the 10th century BCE is found through about 6000 objects excavated from the site. These were dedications buried in the ashes around the altar of Zeus. In the thick layer of ash that formed around it, archeologists have found votive offerings of clay and bronze figures by the faithful.
