The omphalos is the sacred stone of Delphi whose Greek name means “navel.” It symbolically marks the center of the world in the Delphic tradition. One story tells that Zeus released two eagles from the ends of the world and that their meeting identified Delphi as the center. The stone thus becomes a sign of centrality, sanctuary, and oracular authority. In Greek art, Apollo may be depicted seated on the omphalos, recalling the relationship between the stone and his oracle.

Why does the word omphalos mean center?
In Greek, omphalos means navel. The human body thus provides a metaphor for centrality: the navel marks a visible midpoint on the abdomen.
Applied to Delphi, the term transforms a stone into the symbolic center of the Greek world. Sacred geography is not based on modern cartographic measurement, but on a religious logic.
The British Museum preserves objects and coins showing the omphalos as an identifiable stone of the sanctuary. Its presence is enough to evoke Delphi and Apollo.
What does the myth of the two eagles tell?
According to a Greek tradition, Zeus releases two eagles from opposite points of the world. The birds meet at Delphi, revealing the center of the world.
An Attic lekythos at the British Museum depicts the omphalos between two eagles. The object thus gives the story a direct visual form.
The myth does not seek to calculate a geometric center of the Earth. It asserts Delphi’s religious status as a central place of communication with Apollo.
Why is the god seated on the stone?
Apollo may be depicted seated on the omphalos, holding a lyre or laurel branch. Coins from Delphi preserved at the British Museum precisely show this iconography.
The god, the stone, and the sanctuary thus become inseparable. Showing Apollo on the omphalos amounts to showing the master of the oracle at the center of his domain.
This image gives the stone a value far greater than that of a simple monument: it materializes the authority of the prophetic site.
What role does the symbol play at Delphi?
Delphi is one of the most prestigious sanctuaries in the Greek world. Cities and individuals came to consult Apollo’s oracle about political, military, and personal decisions.
The omphalos asserts that this message comes from a central place. The sanctuary presents itself as the point where the human world can receive divine guidance.
The symbol’s centrality can be compared with the center of the labyrinth, but the two traditions do not have the same history: the omphalos is a concrete cult stone, not a geometric pathway.
Why is the word still used to refer to a sacred center?
The term “omphalos” has become a scholarly way of designating a religious or symbolic center. Historians of religion use it to discuss places presented as the center of the world in several traditions.
This modern extension stems from the strength of the Delphic case: a stone named “navel” that explicitly marks the centrality of the sanctuary.
Prudence consists in not turning every sacred center in the world into a derivative of Delphi. The word can serve as a comparison, but each culture has its own language of the center.
