The poet now graphically describes how, by means of his wings or on foot, Satan scrambles up high battlements and plunges down deep abysses, thus gradually working his way to the place where Chaos and Night sit enthroned, contemplating the world "which hangs from heaven by a golden chain." Addressing these deities, Satan commiserates them for having lost Tartarus, now the abode of the fallen angels, as well as the region of light occupied by the new world. When he proposes to restore to them that part of their realm by frustrating God's plans, they gladly speed him toward earth, whither "full fraught with mischievous revenge accursed in an accursed hour he hies." _Book III._ After a pathetic invocation to light, the offspring of heaven, whose rays will never shine through his darkness, Milton expresses a hope that like other blind poets and seers he may describe all the more clearly what is ever before his intellectual sight. Then he relates how the Eternal Father, gazing downward, contemplates hell, the newly-created world, and the wide cleft between, where he descries Satan "hovering in the dun air sublime." Summoning his hosts, the Almighty addresses his Only Begotten Son,--whose arrival in heaven has caused Satan's rebellion,--and, pointing out the Adversary, declares he is bent on revenge which will redound on his own head. Then God adds that, although the angels fell by their own suggestion, and are hence excluded from all hope of redemption, man will fall deceived by Satan, so that, although he will thus incur death, he will not forever be unforgiven if some one will pay the penalty of his sin. Because none of the angels feel holy enough to make so great a sacrifice, there is "silence in heaven," until the Son of God, "in whom all fulness dwells of love divine," seeing man will be lost unless he interferes, declares his willingness to surrender to death all of himself that can die. He entreats, however, that the Father will not leave him in the loathsome grave, but will permit his soul to rise victorious, leading to heaven those ransomed from sin, death, and hell through his devotion. The angels, hearing this proposal, are seized with admiration, and the Father, bending a loving glance upon the Son, accepts his sacrifice, proclaiming he shall in due time appear on earth in the flesh to take the place of our first father, and that, just "as in Adam all were lost, so in him all shall be saved." Then, further to recompense his Son for his devotion, God promises he shall reign his equal for ever and judge mankind, ere he bids the heavenly host worship their new master. Removing their crowns of amaranth and gold, the angels kneel before Christ in adoration, and, tuning their harps, sing the praises of Father and Son, proclaiming the latter "Saviour of man."
