Omphalos
An omphalos is a religious stone artefact. In Ancient Greek, the word wikt:ὀμφαλός means "navel". Among the Ancient Greeks, it was a widespread belief that Delphi was the center of the world. According to the myths regarding the founding of the Delphic Oracle, 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 that was the place where Zeus placed the stone. The Latin term is umbilicus mundi, 'navel of the world'.
Omphalos is also the name of the stone given to Cronus.
Delphi
Most accounts locate the Delphi omphalos in the adyton near the Pythia. The stone sculpture itself, which may be a copy, has a carving of a knotted net covering its surface and a hollow center, widening towards the base. The omphalos represents the stone which Rhea wrapped in swaddling clothes, pretending it was Zeus, in order to deceive Cronus.Omphalos stones were believed to allow direct communication with the gods. Holland suggested that the stone was hollow to allow intoxicating vapours breathed by the Oracle to channel through it. Erwin Rohde wrote that the Python at Delphi was an earth spirit, who was conquered by Apollo and buried under the Omphalos. However, understanding of the use of the omphalos is uncertain due to destruction of the site by Theodosius I and Arcadius in the 4th century CE.

Dick, Jacques Derrida, Ted Chiang, Sandy Hingston and Seamus Heaney.

In "The Toome Road", a Seamus Heaney poem from the 1979 anthology Field Work, Heaney writes about an encounter with a convoy of armoured cars in Northern Ireland, "… O charioteers, above your dormant guns,
It stands here still, stands vibrant as you pass,
The invisible, untoppable omphalos."
