The scene returns to Heaven, where God knows immediately that Adam and Eve have eaten from the Tree of Knowledge. Gabriel and the other angels guarding Paradise also know, and they fly back up to Heaven. They report that they did all they could to prevent Satan from re-entering the Garden. God tells them that he allowed it himself without condoning it, and acquits his angels of any guilt. He then sends his Son down to Earth to pass judgment on the couple.
In Paradise, the Son calls to Adam, who comes forth shamefacedly along with Eve. They are embarrassed by their nakedness. Asked if they have eaten from the tree, Adam admits that Eve gave the fruit to him to eat, and Eve blames the serpent for persuading her to take it. The Son first condemns the serpent, whose body Satan possessed to tempt Eve. He ordains that all snakes now must crawl on their bellies, never to carry themselves upright again. The Son decrees that Adam and Eve’s children will bruise the serpent’s head, while serpents will forever bite humans by the heel. As punishment for the couple, Eve and all women to follow will give birth in pain, and must submit to their husbands. Likewise, Adam and all men after him will have to labor to hunt and harvest food in cursed ground. After passing these sentences, the Son returns to Heaven.
Meanwhile in Hell, Sin and Death remain at the gate of Hell where Satan left them. Sensing that Satan has succeeded in his task, they finish the bridge linking Hell to Earth and begin to travel toward Earth to meet him. At the edge of Paradise, Sin and Death meet Satan. They congratulate him for succeeding in his mission and promise him that they will infect the Earth. Death will corrupt all living things, causing them to die, and Sin will corrupt the thoughts and deeds of humankind. They also tell Satan that his success must have allowed them to leave Hell, proving that he has established his control over humankind and Earth. Satan thanks Sin and Death for their praises and urges them to hurry on their way to conquer Earth. Satan believes that he has in fact acquired the special powers Sin and Death spoke of, when in truth God allows them to enter Earth so that the Son can conquer them when he becomes human. Now, Satan goes back down to Hell, where his followers have been eagerly waiting his return. Satan speaks to them from Pandemonium, tells them of his triumph, and expects to hear riotous applause. Instead, he hears hisses signifying scorn for him and his devastating act. The devils have all been transformed into snakes, along with Satan, who did not understand the punishment the Son foretold. A grove of trees appears in Hell, with fruit that turns to ashes as soon as the snakes try to bite it.
Sin and Death arrive on Earth and begin their work. From Heaven, God sees that they have come to Earth and tells his angels that he will allow Sin and Death to stay on Earth until Judgement Day. After then, they must return to Hell and be forever locked up with Satan and the other devils.
God now calls for his angels to alter the universe. They tilt the Earth’s axis or alter the path of the sun (the poem allows for both interpretations). Now humankind will have to endure extreme hot and cold seasons, instead of enjoying the constant temperate climate that existed before Adam and Eve’s fall from God’s grace. Meanwhile, Discord follows Sin to Earth and causes animals to war with each other and with humans too. Seeing these changes, Adam is sorrowful, and laments. He knows that the rest of humankind will suffer because of his disobedience, and wishes that he could bear all of the punishment upon himself. He curses life and wishes that Death would come at once to alleviate his misery. Instead, Eve comes to him. But Adam is angry; he blames and insults Eve’s female nature, wondering why God ever created her. She begs his forgiveness, and pleads with him not to leave her. She reminds him that the snake tricked her, but she fully accepts the blame for sinning against both God and him. She argues that unity and love can save them in a fallen world. She longs for death and suggests that they take their own lives, but Adam forbids it. Eve’s speech affects Adam. He becomes calm, consoling her and sharing responsibility for their fall. They must stop blaming each other, he says. They must live with their mistakes and make the most out of their fallen state. Remembering the prophecy that Eve’s seed would bruise the head of the serpent, he feels that there is hope for humankind and advises that they obey God and implore his mercy and forgiveness. They return to the spot where they were punished. There, they fall to their knees, confess their sins, and ask for forgiveness.
If Book IX presents the climax of Paradise Lost, then Book X presents its resolution, as the punishments that the Son hands out restore some sort of order to the world. Satan and the other supporting characters disappear from the rest of the poem, eliminating the source of human temptation and thus focusing the poem on Adam and Eve’s regret. But Adam and Eve begin to redeem humankind with their repentance at the end of Book X. As a result, these characters will disappear from the story, and humankind’s predicted redemption will take precedence as the story continues, with Adam and Eve learning about their fallen future.
The devils’ punishment to live as snakes forever tempted by fruit on a glorious tree echoes Satan’s temptation of Eve. Now they must forever suffer the pains of desire without ever having hope of attaining their wishes, a punishment befitting their crime. To have the devils frozen in a state of perpetual desire and unattainable satisfaction is fit for a group of evildoers who continue to battle God through their disobedience.
Milton uses the concept of typology—the Christian belief that Old Testament characters symbolize and predict New Testament characters—to demonstrate the intimate relationship between the fall of humankind and the redemption of humankind. This relationship between the fall and the resurrection forms the base of the Christian interpretation of the Bible. Milton considers Mary, the mother of the Son (Jesus), to be the “second Eve.” As Sin and Death came into the world through Eve, the Son would conquer Sin and Death through Mary. Likewise, Milton considers Jesus to be a “second Adam” who corrects Adam and Eve’s disobedience through his resurrection. Through these comparisons between Eve and Mary, and Adam and Jesus, the fall and the resurrection become intertwined. The fall is the cause of human history; the resurrection is the result of human history.
Although Adam and Eve are ailing at the end of Book IX, they take action in Book X and separate their fate from Satan’s fate. Satan, as Milton shows, cannot allow himself to repent. His damnation is permanent since his disobedience comes from within and without repentance. On the other hand, humankind’s disobedience comes from the temptation of another. This idea helps to explain Adam and Eve’s actions and subsequent punishment at the end of Book X. Realizing the terrible consequences of their actions, they come dangerously close to rationalizing suicide, but Adam decides to beg God for forgiveness—the only right answer, in Milton’s opinion. Though the coming of the Son and the salvation of humankind had already been foretold, the couple’s decision to repent is crucial in God’s willingness to forgive them. God will show mercy when asked, but as we see with Satan, there can be no mercy without repentance. In one of the most important quotations in Paradise Lost, Milton poetically demonstrates the importance of Adam and Eve’s decision in the last several lines of Book X. Adam explains how their repentance and prayer will occur, and then as they pray, Milton duplicates Adam’s explanation as the actual action of their prayer. As Adam explains to Eve:
What better can we do, than to the place
Repairing where he judg’d us, prostrate fall
Before him reverent, and there confess
Humbly our faults, and pardon beg, with tears
Watering the ground. . .
This moment of prayer is crucial because now humankind will not all go the way of Satan, because man produces what the devil could not: true sorrow and regret.
Milton gives Eve the ability to argue persuasively to Adam, showing her intelligence and talents after all. Eve displays a new humility and grace when she repents after the fall. Her strength lies in her ability to relate her feelings to Adam, feelings that Adam shares. Eve’s contemplation of suicide is a sign of weakness, but after Eve’s moving speech, Adam is able to help see—and to help her see—why they should not commit suicide. As they lose hope of Paradise, they witness the hope of their race: God’s Son, Jesus. It is this hope that prevents the couple from taking their own lives when they realize the extent of their punishment. They choose hope over despair. Milton resolves their distinguished differences through a display of unity: Eve’s loving and emotional arguments to stay together and Adam’s rational argument to repent help them begin to save humankind together. Their similarities and teamwork, not their differences and occasional parity, allow them to obey reason and survive.
