elphi is both an archaeological site and a modern town in Greece on the south-western spur of Mount Parnassus in the valley of Phocis. In myths dating to the classical period of Ancient Greece (510-323 BC), the site of Delphi was believed to be determined by Zeus when he sought to find the center of his “Grandmother Earth” (Gaia). He sent two eagles flying from the eastern and western extremities, and the path of the eagles crossed over Delphi where the omphalos, or navel of Gaia was found.
Delphi is perhaps best known for the oracle at the sanctuary that was dedicated to Apollo during the classical period. According to Aeschylus in the prologue of the Eumenides, it had origins in prehistoric times and the worship of Gaia. Earlier myths include traditions that Pythia, or the Delphic oracle, already was the site of an important oracle in the pre-classical Greek world (as early as 1400 BC) and, rededicated, served as the major site during classical times for the worship of the god Apollo after he slew Python, “a dragon” who lived there and protected the navel of the Earth.
