The Omphalos, often represented as a stone or a navel-like figure, is a significant symbol in various cultures, embodying the concept of the 'navel of the world' or the center of the universe. Most famously associated with the ancient Greeks, the Omphalos stone was located at Delphi, regarded as the site where Apollo spoke through oracles. It symbolizes both the physical and spiritual center of existence, often representing rebirth, renewal, and the cycle of life. In modern tattoo art, the Omphalos can incorporate elements like spirals or geometric patterns, enhancing its mystical representation. Ideal placements for the tattoo include the chest or back, where its significance can resonate as a personal touchstone. Variations across cultures might include indigenous interpretations, making it versatile in design while maintaining its profound meaning.
