Beowulf vs Luke

Luke Skywalker and Beowulf have a lot of similarities and differences when it comes to relating them to being heros. For one, Beowulf was born into royalty, while Luke was not. They were both basically born to be heros. Luke's father was a fighter so it's only likely that his child follow in his footsteps. Beowulf was born to fight because he's basically the best fighter around. He felt he was destined to fight and it seems that Luke will start to realize this too as the plot goes on.
They both also have similar calls to actions, however. Beowulf must fight because a neighboring area is in need of help and he feels it's his duty to save them. Luke is called to fight because Obi Wan needs his help delivering a message in order to save the area. Though Luke doesn't accept the challenge right away it's still similar to Beowulf's because it's being the hero to a certain area in the world (or galaxy). We later find out that he mainly fights because his parents were killed by opposing forces.
A difference between the two would be their mystic weapons. Beowulf's mystic weapon would be the sword he received to fight Grendal's mother. Luke's weapon would be the force that he begins to discover as the movie progresses.
In the end of Star Wars, Luke really hasn't mastered two worlds yet. We sort of get a sense that in time he will be able to master two worlds, but not yet. Beowulf, on the other hand, ended with Beowulf being the master of both Denmark and Geatland.
