omphalos
Quick Summary
The term "omphalos" originates from the ancient Greek word for "navel". In Greek religion, it specifically referred to a sacred, rounded stone located in the Temple of Apollo at Delphi. This stone was believed to mark the exact center of the Earth. The ancient Greeks considered Delphi to be the "navel of the world". According to myth, Zeus released two eagles that met at Delphi, marking it as the world's center, and the omphalos stone symbolized this spot. The word "omphalos" has also been adopted into English to mean a central point or hub.123
