A hero of the Poetic Edda, Sigurd was born after the death of his father. Sigurd's mother gave him the broken shards of his father's sword, which later was remelded to help Sigurd kill the dragon Fafnir. The sword was so strong that it cut through the anvil used to make it. Odin told Sigurd to dig trenches to hide in as he stabbed at Fafnir. Odin also told him to bathe in the dragon's blood. Following Odin's advice, Sigurd killed the dragon and bathed in his blood, which touched all his body except for his shoulder where a leaf had stuck. Next, he drank the blood and could speak to birds. Roasting the heart and eating it, he gained the gift of prophecy.
