This egg-shaped stone—the very stone described by the Greek writer Pausanias, who visited Delphi in the second century A.D.—represents the omphalos, or “navel of the world.” According to Greek legend, Delphi was fixed as the center of the world when Zeus released two eagles, one from the west and the other from the east, which met in the sky above Delphi. The original omphalos stone, now lost, was probably an archaic cult object that supplicants draped with wreaths, resembling the wreaths carved in relief on this stone.
