After exchanging Homeric taunts, these two begin fighting, and Abdiel's first dart causes the archenemy to recoil and almost sink to the ground. But, when the divine host clamor that Satan is overcome, he promptly recovers his footing, and, retreating into the ranks of his army, directs their resistance to the foe. The battle now rages with such fury that the heavens resound. Many deeds of eternal fame are wrought, for Satan proves almost equal to Michael, who with his two-handed sword strikes down whole squadrons at one blow. But wounds inflicted on angels, even when fallen, are no sooner made than healed, so those who sink down disabled are soon back in the thick of the night as strong as ever. The moment comes, however, when Michael's sword inflicts so deep a wound in Satan's side that, for the first time, he experiences pain. Seeing him fall, his adherents bear him away from the field of battle, where he is immediately healed, "for spirits, that live throughout vital in every part,… cannot but by annihilation die." Thus temporarily deprived of his greatest opponent, Michael attacks Moloch, while Uriel, Raphael and Abdiel vanquish other potent angels who have dared to rebel against God.
After describing the battle-field, strewn with shattered armor and broken chariots, the poet pictures the dismay in the ranks of the rebel angels, and describes how Satan drew away his troops so they might rest and be ready to renew the fray on the morrow. In the silence of that night, he also consults with his adherents how to fight to better advantage on the morrow, insisting that they now know they can never be permanently wounded. The demons feel confident that, granted better arms, they could secure the advantage, so, when one of their number suggests the manufacture of cannon, all gladly welcome the idea. Under Satan's direction some of the evil angels draw from the ground metal, which, molten and poured into moulds, furnishes the engines of destruction they are seeking. Meanwhile others collect ingredients for ammunition, and, when morning dawns, they have a number of weapons ready for use, which they cunningly conceal in the centre of their fourfold phalanx as they advance.
In the midst of the second encounter, Satan's squadrons suddenly draw aside to let these cannons belch forth the destruction with which they are charged, an unexpected broadside which fells the good angels by thousands; but, although hosts of them are thus laid low, others spring forward to take their place. On seeing the havoc wrought by their guns, Satan and his host openly rejoice; but the good angels, perceiving arms are useless against this artillery, throw them away, and, picking up the hills, hurl them at their opponents, whom they bury beneath the weight of mountains. In fact, had not the Almighty checked this outburst of righteous anger, the fiends would doubtless have been buried so deep they never would have been able to reappear!
On the third day the Almighty proclaims that, as both forces are equal in strength, the fighting will never end unless he interferes. He therefore summons his only begotten Son to wield the thunder-bolts, his exclusive weapon. Ever ready to do his Father's will, the Son accepts, mounts a chariot borne by four cherubs, and sets forth, attended by twenty thousand saints, who wish to witness his triumph. On seeing him approach, the good angels exult, while the wicked are seized with terror, although they disdain to flee. Bidding the angelic host watch him triumph single-handed over the foe, the Son of God changes his benignant expression into one of wrath, and hurls his thunder-bolts to such purpose that the rebels long for the mountains to cover them as on the previous day. With these divine weapons Christ ruthlessly drives Satan and his hosts out of the confines of heaven, over the edge of the abyss, and hurls them all down into the bottomless pit, sending after them peal after peal of thunder, together with dazzling flashes of lightning, but mercifully withholding his deadly bolts, as he purposes not to annihilate, but merely to drive the rebels out of heaven. Thus, with a din and clatter which the poet graphically describes, Satan and his host fall through space and land nine days later in the fiery lake!
After pursuing the foe far enough to make sure they will not return, the Messiah re-enters heaven in triumph, greeted by saints and angels with hymns of praise. This account of the war in heaven concluded, Raphael informs Adam that Satan, leader of these fallen angels, envying his happy state, is now plotting to seduce him from his allegiance to God, and thus compel him to share his eternal misery.
"But listen not to his temptations; warn
Thy weaker; let it profit thee to have heard
By terrible example the reward
Of disobedience; firm they might have stood,
Yet fell; remember, and fear to transgress."
Book VII. At Adam's request Raphael next explains how the earth was created, saying that, as Satan had seduced one-third of heaven's inhabitants, God decided to create a new race, whence angels could be recruited to repeople his realm. In terms simple enough to make himself understood, Raphael depicts how the Son of God passing through heaven's gates and viewing the immeasurable abyss, decided to evolve from it a thing of beauty. He adds that the Creator made use of the divine compasses "prepared in God's eternal store," to circumscribe the universe, thus setting its bounds at equal distance from its centre. Then his spirit, brooding over the abyss, permeated Chaos with vital warmth, until its various components sought their appointed places, and earth "self-balanced on her centre hung." Next the light evolved from the deep began to travel from east to west, and "God saw that it was good."
On the second day God created the firmament, on the third separated water from dry land, and on the fourth covered the earth with plants and trees, each bearing seed to propagate its kind. Then came the creation of the sun, moon, and stars to rule day and night and divide light from darkness, and on the fifth day the creation of the birds and fishes, whom God bade multiply until they filled the earth. Only on the sixth and last day did God call into life cattle and creeping things, which crawled out of the earth full grown and perfect limbed. Then, as there still lacked a creature endowed with reason to rule the rest, God created man in his own image, fashioning him from clay by breathing life into his nostrils. After thus creating Adam and his consort Eve, God blessed both, bidding them be fruitful, multiply and fill the earth, and hold dominion over every living thing upon it. Having placed creatures so richly endowed in Paradise, God left them free to enjoy all it contained, save the fruit of the tree of knowledge of good and evil, in regard to which he warned them "in the day thou eatest thereof, thou diest." Then, his work finished, the Creator returned to heaven, where he and the angels spent the seventh day resting from their work.
Book VIII. Not daring to intrude upon the conversation of Adam and Raphael, Eve waits at a distance, knowing her husband will tell her all she need learn. Meanwhile, further to satisfy his curiosity, Adam inquires how the sun and stars move so quietly in their orbit? Raphael rejoins that, although the heavens are the book of God, wherein man can read his wondrous works, it is difficult to make any one understand the distances separating the various orbs. To give Adam a slight idea of them, Raphael declares that he—whose motions are not slow—set out from heaven at early morn and arrived at Eden only at midday. Then he describes the three rotations to which our earth is subject, names the six planets, and assures Adam God holds them all in his hand and prescribes their paths and speed.
In his turn, Adam entertains Raphael with a description of his amazement when he awoke on a flowery hillside, to see the sky, the woods, and the streams; his gradual acquaintance with his own person and powers, the naming of the animals, and his awe when the divine master led him into Paradise and warned him not to touch the central tree. After describing his loneliness on discovering that all living creatures went about in pairs, Adam adds that, after he had complained to the Creator, a deep sleep fell upon him, during which a rib was removed from his side from which to fashion Eve. Joined by the Creator himself to this "bone of his bone and flesh of his flesh," Adam declares since then they have enjoyed nuptial bliss, and artlessly inquires whether angels marry and are given in marriage too. Whereupon Raphael rejoins that in heaven love so refines the thoughts and enlarges the heart that none save spiritual communion is necessary to secure perfect bliss. Then, seeing the sun about to set, the angel takes leave of Adam and wends his way back to heaven, while the father of mankind rejoins his waiting wife.
