In Celtic mythology, the number three, in conjunction with the triquetra, represents various concepts of wholeness and unity. Common interpretations include: - The aspects of the triple goddess (maiden, mother, crone)
- The planes of existence (past, present, future, or birth, life, death)
- The connection between body, mind, and soul
- The elements of earth, water, and air
- The divine triad (a unity of three deities)
