Herrauðr, Herraud, Herröðr, Herruðr, Herrud, Herothus or Heroth is a legendary earl of Götaland or king of Sweden, who appears in several medieval legends, in particular those relating to Ragnar Lodbrok (e.g.
His main role in the sagas is as the father of Þóra Borgarhjǫrtr who gave his daughter one or two small lindworms which grew so big that he had to promise her to the man who could slay the serpent(s).
In Krákumál, the dying Ragnar Lodbrok sings that a more famous earl than Herröðr had never steered his longship into a harbour [1].
Through magic and threats, Busla, Bósi's foster-mother, prevailed on Ring to send the two young men on a dangerous quest instead of executing them.
The two young men went to Bjarmaland and killed the vulture guarding the temple of Jumala and the priestess Kolfrosta.
The Bjarmians invaded Östergötland, killed king Ring and took Hleið back to Bjarmaland.
Herrauðr became the new king of Östergötland, while Bósi ascended the throne of Bjarmaland together with his queen Edda.
He had given her a lindworm, but after some time, it had encircled her bower and threatened anyone who approached it, except for her servants who fed it with an ox every day.
When Ragnar heard of this, he went to Västergötland and dressed himself in shaggy clothes that he had treated with tar and sand.
