The Valknut, also known as Hrungnir’s heart, heart of the slain, Heart of Vala, and borromean triangles is a mysterious Norse symbol. its true meaning is still debated, but it is often associated with a warrior’s death in a battle.
The symbol has been found on old Norse stone carvings and funerary steles. It is sometimes called “Hrungnir’s heart,” after the legendary giant of the Eddas. It’s also possible to find a depiction of the Valknut on stone carvings as a funerary motif, where it probably signified the afterlife. In art, the Valknut is a representation of God Odin, and it demonstrates gods’ power over death. A Valknut is also believed to offer protection against spirits which is the reason why it is often carried as a talisman.
A Valknut is made of three parts, and the number three is a very common magic symbol in many cultures. In this case, the symbolism in Norse mythology showing three multiplied by three might designate the nine worlds, which are united by the Yggdrasil tree. In modern times Valknut, like Triquetra and Horn Triskelion, is often interpreted as a symbol pointing to heathen convictions.
