The Trinity Knot, the Triquetra, is the most accurate Celtic symbol for unconditional love. This is one of the most iconic Celtic Knots for a good reason. Examples can be found on stone carvings and crosses, ancient jewelry, and illuminated manuscripts like the Book of Kells. It features three points, flowing with no start or end, and is said to represent eternity. Wiccans believed everything of relevance came in threes, and there are many schools of thought about what the three points symbolize.
Popular theories say they represent; the maiden, the mother, the crone; the holy trinity; and past, present, and future. Some romantics believe the Trinity Knot represents the soul. The three points are the mind, body, and spirit, while the unending pattern symbolizes eternity; life, death, and rebirth. From this viewpoint, giving someone the Trinity Knot is like giving them your soul, an eternal gift to show eternal love.
