I'm fairly sure the head was supposed to be Mímir, one of the Norse gods representing wisdom.
Presumivelmente, como resultado de suas drogas, parece que Ragnar estava imaginando o chefe de Mímir em sua tenda, pedindo-lhe conselhos sobre o plano de ação de Ragnar.Mímir (Old Norse "The rememberer, the wise one") or Mim is a wisdom deity in Norse mythology. He is closely associated with a magical well of knowledge that bears his name, the Mímisbrunnr. At the conclusion of the Æsir-Vanir War he was sent to the Vanir along with the god Hœnir as part of a peaceful hostage exchange. Fearing trickery from the Aesir because of Hœnir's foolishness, the Vanir beheaded Mímir and returned his head to Asgard. In order to keep Mímir's wisdom, Odin preserved his head with magic so it could continue to provide knowledge and counsel as his advisor.
