The Omphalos of Delphi is an ancient marble monument that was found at the archaeological site of Delphi, Greece. According to the Ancient Greek myths regarding the founding of the Delphic Oracle, the god 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, and so was the place where Zeus placed the stone. Since then, Delphi has been considered by Greeks to be the center of the world, the Omphalos – "navel of the Earth."The Omphalos of Delphi is an ancient marble monument that was found at the archaeological site of Delphi, Greece.
