"Among the Ancient Greeks, it was a widespread belief that Delphi was the center of the world. According to the myths regarding the founding of the Delphic Oracle, Zeus, in his attempt to locate the center of the earth, launched two eagles from the two ends of the world, and the eagles, starting simultaneously and flying at equal speed, crossed their paths above the area of Delphi. From this point, Zeus threw a stone from the sky to see where it will fall. The stone fell at Delphi, which since then was considered to be the center of the world, the omphalos — 'navel of the earth'. Indeed, the same stone thrown by Zeus took the same name and became the symbol of Apollo, the sacred Oracle and more generally of the region of Delphi."
