Triquetra

The Celtic Trinity Knot

Three arcs, one unbroken line: distinct forces that hold only because each relies on the others.

The Triquetra, often called the Trinity Knot, is one of the most recognizable Celtic symbols, defined by three interconnected arcs that form a continuous, unbreakable loop. Historically found on Insular art, runestones, and early illuminated manuscripts, it embodies the profound Celtic belief in the triad—a concept that permeates their cosmology. It symbolizes the three domains of earth, sea, and sky, the three stages of life (maiden, mother, crone), and the intertwining of mind, body, and spirit. In esoteric thought, it represents the eternal rhythm of creation, preservation, and destruction, revealing how distinct forces rely on one another to maintain universal balance.
