The center of the Ancient Greek world is in the town of Delphi. This stone is called the Omphalos, or “navel” of the world. Think of it as Mother Earth’s bellybutton.
A long time ago, Zeus wanted to find the center of the world, so he sent two eagles — one from each end of the earth. When they met at Delphi, Zeus sent down the Omphalos, a stone that his father ate and regurgitated (thinking he was eating his son Zeus) as navel of the world.
Omphalos Syndrome is the belief that the city with the most money and most powerful politicians is in fact the center of the world.
So, where is the center of the world? It used to be by the temple of Apollo at Delphi, where the great oracle Sibyl gave prophesy. Now, it’s just up the road at the new museum.
