The triquetra is a symbol closely related to Valknut and Triple Horn of Odin. The artifacts with Triquetra have been found in all parts of the world reached by the Vikings. In Latin, Triquetra means “triangular”. Initially, it was used to describe any triangle, but now it is used to describe a shape formed by three interlocked semicircles at the point where the three circles overlap. They form interlocking Vesica Piscis (Latin “blisters of fish”), or mandorla (in Italian, almond). It is almost certain that the symbolism of Triquetra is related to the ancient Norse religion. However, it is difficult to determine exactly what this symbol meant for Vikings since Triquetra was also used by Christians at a very early stage.
