She adds that she dares not unlock the gates, but, when Satan urges that if she will only let him pass, she and Death will be supplied with congenial occupations in the new world, she produces a key, and, "rolling toward the gates on scaly folds," flings wide the massive doors which no infernal power can ever close again.

Through these gaping portals one now descries Chaos, where hot and cold, moist and dry contend for mastery, and where Satan will have to make his way through the elements in confusion to reach the place whither he is bound.
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.
