Perhaps the most important literary influence on
Cain was
John Milton's epic poem
Paradise Lost, which tells of the creation and fall of mankind. For Byron as for many Romantic poets, the hero of
Paradise Lost was Satan, and Cain is modelled in part on Milton's defiant protagonist. Furthermore, Cain's vision of the Earth's natural history in Act II is a
parody of Adam's consolatory vision of the history of man (culminating in the coming and sacrifice of
Christ) presented by the
Archangel Michael in Books XI and XII of Milton's epic. In the preface to
Cain, Byron attempts to downplay the influence of poems "upon similar topics", but the way he refers to
Paradise Lost suggests its formative influence: "Since I was twenty, I have never read Milton; but I had read him so frequently before, that this may make little difference." Another influence was medieval
mystery plays, "the ancient title annexed to dramas upon similar subjects," though it is unclear the extent to which he would have read these. ==Other influences==
