The triquetra is a geometric symbol consisting of three interlocking arcs or loops, forming a triangular shape. It is often associated with concepts of unity and interconnectedness, representing the idea that three elements can come together to form a whole. The symbol has roots in various cultures, including Celtic and Norse traditions, where it is sometimes linked to the concept of the triple goddess. In modern contexts, the triquetra is frequently used in pagan and Wiccan practices, symbolizing the connection between earth, sea, and sky, or life, death, and rebirth. It can also be found in art, jewelry, and tattoos, often signifying spiritual beliefs or personal values.
