Omphalos refers to a sacred stone or a symbolic 'navel' of the world, often associated with the ancient Greek site of Delphi. This term is particularly linked to the idea that Delphi was the center of the earth, believed to be the location where the two eagles sent out by Zeus met after flying across the world. It also represents the connection between the divine and humanity, emphasizing Delphi's role as a significant oracle.
