Paradise Lost, an epic poem by John Milton written in 1667, heavily influenced the Romantic movement and Romantic poets like Shelley. The Romantics felt that Milton’s personification of Satan in
Paradise Lost framed Satan as the hero of the story because he is determined to provide humans with knowledge against the wishes of God, who is an omnipotent authority. However, while the Romantics admired Satan’s heroic qualities in Milton’s poem, Shelley recognizes that Satan is an evil character because he is envious and vengeful towards mankind and does not offer them knowledge to help them but, instead, to simply spite God. Prometheus, on the other hand, is well-meaning towards humanity
and is free from the evil qualities associated with Satan.
