Humans are, by nature, self-centered. We assumed the sun revolved around the earth until Copernicus and Galileo postulated otherwise... but the religious world was loath to believe them. People of faith often hold their assumptions sacred, and they also exhibit a hometown pride that would rival any modern sports team. Take the map above, for example. Three vastly different cities, three societies that saw themselves as the nucleus of divinity. Navel stones were carved in all three locations to amplify their significance and, much like the holy trinity, the ancient oracle sites of Mt. Ararat, Thebes and Dodona form a perfect triangle when mapped.
Throughout history and across every continent, citizens of various communities have posited that theirs was the center of the spiritual universe. This notion goes by many names: axis mundi, omphalos, world pillar, the earth's navel - a belief that your nation/state/city is the epicenter of a particular denomination. The ancient Incas went so far as to name their capital city Cuzco, which is Quechua for "navel." Societies build grand structures to denote their status as the spiritual center of the world, from the pyramids of Teotihuacan to the Holy Temple in Jerusalem. But one of the most fascinating phenomena is the crafting and implementation of navel stones.
