The Valknut, also known as “Hrungnir’s heart,” was initially discovered on old Norse stone carvings for the gigantic Hrungnir of the Eddas and is best known as the Valknut, or “knot of the slain.” It has been discovered on a number of stone carvings with burial patterns, and is supposed to represent the afterlife. The three overlapping shapes and nine points of the Valknut are sometimes believed to symbolise rebirth, pregnancy, and reincarnation cycles. The Nine Worlds are also represented by the nine points. Their entwined shape also alluded to the interconnectedness of the three kingdoms of earth, hell, and heaven, as well as the nine domains they contain.
