Gullinbursti ('Golden Bristle'), in Norse Mythology, is Freyr's golden boar, which represents male sexuality and stamina. It is one of the many gifts, including Thor's Hammer (Mjölnir), and Odin's Spear (Gungnir), which the gods only got due to Loki's dangerous bet wit the dwarfs. Without Loki, the gods would have been virtually powerless, and Asgard undefended by it's wall too! Hail Loki!
Gungnir, Odi's spear. The Valknut, the symbol for creation, preservation, and destruction. Hugin, and Munin, Odin's Ravens... Surrounded by the runes, which Odin received by sacrificing himself to himself. Great Design!
