a wager that his steed Sleipnir would be faster than Gullfaxi, the horse of Hrungnir. Sleipnir raced against Gullfaxi and won. Hrungnir went to Valhalla after the race, and there he became known as a giant who could not hold his drink. Not only that, but Hrungnir was also abusive when he was drunk. The gods tolerated his behavior as best as they can. When they reached their limit, the gods in Valhalla asked Thor the god of thunder to do something about Hrungnir. Thor challenged and then defeated Hrungnir in battle. It was noted in the story that Hrungnir's heart had a strange shape, like three triangles locked together. Odin's knot represents many formulas interesting to mathematicians. It is the geometric equivalent of the Borromean rings, which are three interlocked circles wherein the removal of one circle causes the two others to unlink. #vikings #kagoldjewelry #odin #odin'sknot #valknut #valknutpendant #designerjewelry #silverjewelry #edda
