The Valknut is a symbol composed of three interconnected triangles. It can be found as either three separate interwoven triangles, or as one continuous line creating three triangles, like in the example to the left above above.
Valknut means "knot of the valiant dead", and has an unmistakable connection to Odin, the head of the Norse pantheon. However "Valknut" is a modern term for the design, as the original name and definitive meaning have been lost to time. It has been suggested that it could be related to the Triple Horn or the Triskelion.
