Satan
Satan is the poem's most active character. He starts as a proud, powerful angel who refuses to accept God's authority, leads a rebellion, loses, and then redirects his energy toward destroying humanity. Milton gives him charisma and real speeches, but the poem tracks his moral decay across twelve books. By the end, he's a serpent. His arc shows what pride actually costs.
Adam
Adam is the first man, created by God to tend the Garden of Eden. He's intelligent, loving, and genuinely good — but he makes the worst choice in the poem with full knowledge of what he's doing. He eats the forbidden fruit not because he's deceived but because he can't bear to lose Eve. His arc moves from innocence through catastrophic failure to a hard-won understanding of what redemption might mean.
Eve
Eve is created from Adam's rib and is his partner in Eden. She's curious, capable, and the one Satan targets. Satan chooses to approach her alone and uses flattery and false logic to convince her the fruit is safe. She eats first. The poem treats her as genuinely responsible for her choice while also showing that she was manipulated in a way Adam was not.
God (the Father)
God in the poem is all-knowing and all-powerful, but Milton works hard to show Him as just rather than cruel. God watches Satan approach Earth, explains that humans will fall freely, and immediately sets redemption in motion. He speaks in formal, authoritative terms. His role is to establish the moral framework the rest of the poem operates inside.
The Son (Christ)
The Son is God's second person, and He plays two key roles. First, He drives Satan and the rebel angels out of Heaven during the war. Second, He volunteers to become human and die to redeem Adam and Eve's descendants. He also descends to judge Adam and Eve after the Fall, and even in judgment He shows mercy. His arc moves from warrior to redeemer.
Raphael
Raphael is the angel God sends to warn Adam before the Fall. He visits Eden, shares a meal with Adam and Eve, and tells them the full story of Satan's rebellion and the war in Heaven. He also warns Adam not to get too distracted by abstract questions. Raphael is the poem's main storyteller within the story — Books 5 through 8 are largely his account.
Michael
Michael is the angel sent to expel Adam and Eve from Eden after the Fall. Before they leave, he shows Adam a series of visions covering all of human history up to the promise of Christ's redemption. He's stern but not cruel. His role is to close the poem with something other than pure despair — he gives Adam a reason to keep going.
