Byron was a Romantic poet whose celebrity, exile, and scandal made him one of the defining figures of his age. His closet drama Cain: A Mystery (1821) draws on the biblical story of Cain and Abel to stage a direct philosophical confrontation with the problem of evil: Lucifer argues to Cain that God created humanity in ignorance and subjected it to death and suffering without cause or justification. Byron gives Lucifer the better lines. The play caused immediate scandal — bishops denounced it, booksellers were prosecuted — for its sympathetic treatment of the argument against God. Byron died at thirty-six in Greece, having gone to fight for Greek independence.
