BYRON'S Cain, to no one's surprise, is a Byronic hero—disaffected, self-pitying, self-hating, suicidal—but he can be distinguished from such Byronically heroic figures as Lara and Manfred because, for one thing, he is not directly presented to us agonizing over his guilty past. Cain is presented in fact with no past except divine history and he protests, again and again, that this belongs not at all to him but to his blundering parents and God. There is no crime, then, no wretchedly sinful experience, for which this hero can be held responsible, and he is thrust upon us, embittered and complaining, without any personal history to account for the difference between himself and his pious community. Ultimately, however, there is the murder of Abel and, to compare Cain with other Byronic heroes, it should be said the murder replaces the sin or crime in the hero's past which Byron ordinarily leaves obscure. More relevant to my present concern is the fact that the murder has the effect of identifying Cain to himself and his community as none other than Cain, the infamous Biblical murderer. “Am I then my brother's keeper?” he asks.1 The addition of “then” to the notorious question suggests that Cain has read the Bible; it also reveals the curious way in which Byron has conceived this particular hero—as reliving rather than living the Biblical myth. In effect, Byron's Cain is a dramatic creature who plays Cain until, voilà, he murders his brother and discovers he is Cain.
