The Valknut is a symbol from Norse mythology that consists of three interlocking triangles. It is sometimes referred to as the "knot of the slain" or the "knot of the slain warrior." While its exact meaning is debated among scholars and historians, it is often associated with the god Odin and his role as a god of war, death, and wisdom in Norse mythology. The Valknut has been found on various artifacts and runestones throughout Scandinavia, and it is believed to have been a symbol of protection or a symbol associated with the afterlife. It remains a significant symbol in modern Norse neopaganism and Heathenry.
