As the chart above suggests, the Greek mythology was more about the interactions with gods and humans, while the Norse mythology promoted individuality of mortals and immortals, certainly more than the Greek mythology. Even though immortals are not the direct cause of the battle between Theseus and Minotaur, Minotaur was a creature that was influenced by a god. In short, Minos did not sacrifice the beautiful white bull as it was intended, and Poseidon punished him by making his wife fall in love with the bull, and that is how Minotaur was made. However, in the story of Beowulf and the dragon, gods have no place in it. In another story where Beowulf slays Grendel, a giant monster, no gods were related to it.
