 Both the accounts of Willibrod and of Harald are semi-mythical, and integrate mythical and legendary themes from the Nordic pagan tradition into their Christian stories.A syncretized variant of the story of Harald, that has him battling Ragnar Lodbrok to establish Christianity in Denmark, appears in Book Nine of Saxo Grammaticus' Gesta Danorum.Ebbo is the name of a mythical Nordic figure, Ibor, also known as Egil or Orvandil, who is an archer, elf, and smith who turns against the Aesir gods and wages war upon them, and the story of Ebbo of Rheims integrates themes of the divine Ebbo's story, including peasant (non-Aesir) birth and migration.
