Exploring the triquetra further, we come across the notable importance of the number three. The power of three is a concept that is deeply rooted in many cultures and religions, and the triquetra is a powerful representation of this concept.

The Power of Three

The triquetra embodies the potency of three, illustrating diverse tri-cornered shapes and the life cycle encompassing birth, life, and death. The number three holds great significance in many cultures, often symbolizing unity, balance, and the cycle of life. In Celtic cultures, the triquetra was used to symbolize love, honor, and protection, while in Norse culture, the triquetra norse denoted the interconnectivity and balance of all things, particularly the unity of the three realms.

Instances of the ‘power of three’ concept can be found in mythology and religion as well. The Greek Moirai, the Charities, and triple deities all symbolize the notion of three entities operating as a unified entity, which is reflected in the design of the triquetra.

The term ‘Trinity Knot’ symbolizes the unity of body, mind, and spirit, and the concept of the power of three and the Holy Trinity in Christianity. The trinity knot meaning, also known as the Celtic Triangle or the trinity knot symbol, is derived from the term ‘Triquetra’ which represents a shape formed of three vesicae piscium, sometimes with an additional circle, symbolizing things or persons that are threefold.
