The Iliad is not a poem about the whole Trojan War. It does not describe the abduction of Helen, the gathering of the fleet, the wooden horse, or the fall of the city. Its subject is announced in its very first line: “Sing, goddess, the wrath of Achilles, son of Peleus.” Across twenty-four books and some fifteen thousand lines, Homer follows a single emotion — the anger of one man — as it spreads outward and destroys friend and enemy alike, until it finally burns out in an act of compassion.
This page follows the arc of that wrath through the poem. For the life of the hero before and after these events, see Achilles: The Greatest Warrior of the Trojan War.
The Quarrel (Book 1)
The poem opens in the tenth year of the siege. A plague is ravaging the Greek camp. The prophet Calchas reveals its cause: Agamemnon, leader of the Greek host, has refused to return Chryseis, a captured young woman, to her father Chryses, a priest of Apollo. The god, answering his priest’s prayer, is shooting arrows of disease into the camp.
Agamemnon agrees to give Chryseis back — but only if he receives another prize to replace her. Achilles objects: the spoils have already been divided. Agamemnon’s reply is a deliberate humiliation. He will take Achilles’s own prize, the young woman Briseis.
Achilles half-draws his sword to kill Agamemnon on the spot. The goddess Athena, visible only to him, seizes him by his golden hair and restrains him, promising that he will one day receive three times as much in compensation. Achilles sheathes the sword but swears a great oath on the royal sceptre: the day will come when the Greeks long for him, and Agamemnon will gnaw his heart for having dishonoured the best of the Achaeans.
He withdraws to his ships with his Myrmidons. Then he goes down to the shore and weeps to his mother, Thetis, who goes to Olympus and clasps the knees of Zeus. She begs him to give victory to the Trojans until the Greeks honour her son. Zeus nods his assent, and Olympus shakes.
The Greeks Without Achilles (Books 2–8)
The middle books show the war going on without its greatest fighter. Some of the poem’s most famous scenes belong here: the Catalogue of Ships listing the Greek contingents; the duel between Menelaus and Paris, from which Aphrodite rescues Paris in a cloud; the aristeia (the moment of supreme glory) of Diomedes, who wounds even the gods Aphrodite and Ares; and the tender farewell between Hector and his wife Andromache on the walls of Troy, when their baby son Astyanax cries in fear at the nodding plume of his father’s helmet.
Zeus, keeping his promise, gradually tips the balance. By the end of Book 8 the Trojans are camped on the plain outside their walls, their watch-fires burning like stars, ready to drive the Greeks into the sea.
The Embassy (Book 9)
Agamemnon, panicking, admits his error. He sends an embassy — Odysseus, the old tutor Phoenix, and the great fighter Ajax — to offer Achilles an enormous compensation: Briseis returned untouched, tripods, gold, horses, seven captive women, seven cities, and one of Agamemnon’s daughters in marriage.
Achilles refuses. His speech is the philosophical heart of the poem. What is the point, he asks, of fighting for a man who treats the brave and the cowardly alike? Cattle and tripods can be won; a man’s life cannot be won back once it has passed the barrier of his teeth. He reveals the prophecy of his two fates — glory and early death, or long life without fame — and declares that he will sail home.
Phoenix’s appeal and Ajax’s blunt reproach soften him only slightly: he will not sail home, but he will not fight until the Trojans reach his own ships.
The Greeks Driven Back (Books 10–15)
A night raid by Odysseus and Diomedes brings a brief success, but the following day is a disaster. Agamemnon, Diomedes, and Odysseus are all wounded. The Trojans storm the wall that the Greeks have built around their camp. Hector smashes a gate with a boulder and leads his men to the ships themselves. Hera distracts Zeus by seducing him on Mount Ida, allowing Poseidon to rally the Greeks for a time, but when Zeus wakes the Trojan advance resumes. Fire is set to the ship of Protesilaus.
Patroclus Goes to War (Book 16)
Patroclus, Achilles’s closest companion, comes to him weeping. He begs to be allowed to lead the Myrmidons into battle wearing Achilles’s armour, so the Trojans will think the great warrior has returned. Achilles agrees but warns him: drive the Trojans from the ships, then come back. Do not pursue them to the city.
Patroclus’s charge is magnificent. The Trojans break. He kills Sarpedon, son of Zeus, whose father weeps tears of blood. But then, carried away, Patroclus forgets the warning and charges the walls of Troy. Apollo himself strikes him from behind, stunning him and knocking off his armour; a Trojan named Euphorbus spears him in the back; and Hector finishes him with a thrust to the belly. Dying, Patroclus prophesies Hector’s own death at the hands of Achilles.
The Grief of Achilles (Books 17–19)
The Greeks and Trojans fight over the body all day. Hector strips the armour and puts it on. When news reaches Achilles, his reaction is described with extraordinary physicality: he pours dust over his head, lies full-length in the dirt, and tears his hair, while the captive women wail. Thetis hears him from the depths of the sea.
Achilles’s wrath now changes its target. He no longer cares about Agamemnon or Briseis; he wants only to kill Hector, even knowing that his own death must follow soon after. Without armour, he stands at the ditch and shouts three times, and the Trojans panic, allowing the Greeks to recover the body.
Overnight, Hephaestus forges new armour, including the great shield depicting the entire world. In the morning Achilles is formally reconciled with Agamemnon, who returns Briseis and the gifts. Achilles barely notices. He refuses to eat until Hector is dead.
The Rampage (Books 20–22)
Achilles’s return to battle is a slaughter. Even the gods join the fighting. He kills so many Trojans in the River Scamander that the river-god, his channel choked with bodies, rises up to drown him, and only the fire-god Hephaestus, sent by Hera, drives the waters back.
The Trojans flee into the city. Only Hector remains outside the Scaean Gate, ashamed to retreat after his earlier overconfidence cost so many lives. When Achilles approaches, blazing like the dog-star, Hector’s nerve fails and he runs. Three times the two men circle the walls of Troy. Then Athena takes the form of Hector’s brother Deiphobus and persuades him to stand and fight. Hector turns, hurls his spear, and calls for his brother to hand him another — but no one is there. He realizes the gods have deceived him, draws his sword, and charges. Achilles drives his spear through the gap at the throat of the armour that once belonged to Patroclus.
Dying, Hector asks that his body be returned to his family. Achilles refuses with savage contempt. He pierces Hector’s ankles, ties the body to his chariot, and drags it in the dust before the eyes of Hector’s parents and wife.
The Funeral Games (Book 23)
Patroclus is finally given a magnificent funeral. Achilles sacrifices horses, dogs, and — shockingly — twelve Trojan captives on the pyre. Then he holds athletic games in honour of his friend: a chariot race, boxing, wrestling, a foot race, and more. The games reveal Achilles as a generous and fair judge, easing quarrels among the Greek leaders. The wrath is beginning to cool, but every day he still drags Hector’s body around Patroclus’s tomb. Apollo protects the corpse from corruption.
Priam and Achilles (Book 24)
The gods, disgusted by the treatment of Hector’s body, intervene. Zeus sends Thetis to tell her son to accept a ransom, and sends the messenger-goddess Iris to old King Priam of Troy, telling him to go to the Greek camp in person.
Guided by Hermes, Priam slips unseen through the enemy lines and enters Achilles’s hut. He kneels and kisses the hands that killed so many of his sons. He asks Achilles to remember his own father, Peleus, old and alone at home. “I have endured what no one on earth has ever endured before,” Priam says: “to put to my lips the hand of the man who killed my son.”
Both men weep — Priam for Hector, Achilles for his father and for Patroclus. Achilles raises the old man up. He gives back the body, washed and anointed, and grants eleven days’ truce for the funeral. They eat together, and gaze at each other in wonder.
The poem ends quietly, with the Trojans mourning and burying Hector. The final line is: “Such were the funeral rites of Hector, tamer of horses.”
What the Wrath Means
The Iliad is often read as a celebration of war, but its focus on Achilles’s anger makes it something more complex. The wrath is justified at the start — Agamemnon’s insult is real — but it becomes destructive when Achilles lets his comrades die to prove his worth, and inhuman when he mutilates Hector’s body. It is resolved not by victory but by recognition: Achilles sees in Priam a human being who suffers exactly as he does.
The poem’s final scene suggests that the highest heroism is not the ability to kill but the ability to pity. It is a remarkable conclusion for the oldest war poem in the Western tradition, and it is why readers still return to the Iliad nearly three thousand years after it was composed.
