The thesis focuses on the analysis of the character of Satan in Milton's epic poem Paradise Lost, and attempts to define it and contextualize the character’s heroism both in structural and post-structural terms while juxtaposing him with other, more traditional heroes. After giving the brief biography of John Milton, the author of the said epic poem, the essay touches upon the similarity between this unlikely hero, his stances and causes he fights for, and Milton, along with the details from his own life which prove the similarity that Paradise Lost has with the narrative of the Great Chain of being, was Milton's way of subverting the King's rule in 17th century England. The thesis also explores Satan's characteristics, his flaws and attributes, while comparing him to heroes and antiheroes of some of the other works, which in turn helps corroborate the claim that Satan is a hero of Paradise Lost. The thesis comes to the conclusion of why the incarnation of evil banished from heaven could be viewed as a main contributor to the action of the story and plot itself, and therefore a hero of this epic poem.
