Note 122 — Scene II.—Hades.

["Cain is a proud man: if Lucifer promised him kingdoms, etc., it would elate him: the object of the Demon is to depress him still further in his own estimation than he was before, by showing him infinite things and his own abasement, till he falls into the frame of mind that leads to the catastrophe, from mere internal irritation, not premeditation, or envy of Abel (which would have made him contemptible), but from the rage and fury against the inadequacy of his state to his conceptions, and which discharges itself rather against Life, and the author of Life, than the mere living."—Letter to Moore, November 3, 1821, Letters, 1901, v. 470. Here, no doubt, Byron is speaking in propriâ personâ. It was this sense of limitation, of human nothingness, which provoked an "internal irritation ... a rage and fury against the inadequacy of his state to his conceptions." His "spirit beats its mortal bars," not, like Galahad, to be possessed by, but to possess the Heavenly Vision.]
