The Iliad's narrative can be understood as moving through several major movements, each building on Achilles' wrath and its consequences.
Books 1-2: The Quarrel
The Wrath Begins. Agamemnon, commander of the Greek forces, is forced to return his war prize, the girl Chryseis, to her father (a priest of Apollo) after Apollo sends a plague upon the Greek camp. In compensation, Agamemnon seizes Briseis, the war prize of Achilles. Humiliated and dishonoured, Achilles withdraws from battle, taking his elite warriors (the Myrmidons) with him. He prays to his mother, the sea-goddess Thetis, asking her to persuade Zeus to help the Trojansâso the Greeks will realise how much they need him.
Books 3-7: Greeks Without Achilles
Fighting resumes. Paris and Menelaus duel for Helen, but Aphrodite rescues Paris when he's losing. The Trojan Pandarus breaks a truce by shooting an arrow at Menelaus, and full battle erupts. Diomedes has a spectacular day on the battlefield (his aristeia), even wounding the gods Aphrodite and Ares. In Book 6, we see the famous scene of Hector saying farewell to his wife Andromache and infant son Astyanax. Book 7 ends with both sides agreeing to a temporary truce to bury their dead.
Books 8-9: Greek Desperation
Zeus honours his promise to Thetis. The tide turns dramatically against the Greeks. They are driven back to their ships, and Hector threatens to burn the Greek fleet. In desperation, Agamemnon sends an embassy to Achilles in Book 9âOdysseus, Ajax, and Phoenixâoffering magnificent gifts and the return of Briseis if he'll return to fight. But Achilles refuses. His honour has been damaged too deeply, and no amount of gifts can restore it. This is a pivotal moment: the hero rejects the traditional heroic values.
Books 10-15: Continued Greek Losses
The Greeks are pushed to breaking point. Book 10 (the Doloneia) tells of a night raid by Odysseus and Diomedes. In Books 11-15, even the greatest Greek warriorsâAgamemnon, Diomedes, and Odysseusâare wounded. Hector breaks through the Greek defensive wall and the Trojans reach the ships. Poseidon tries to help the Greeks, but Zeus keeps the Trojans victorious.
Books 16-17: Patroclus Dies
The turning point. Achilles' closest companion, Patroclus, can no longer bear to watch the Greeks suffer. He begs Achilles to let him enter battle wearing Achilles' armour, hoping the Trojans will mistake him for Achilles and retreat. Achilles reluctantly agrees. Patroclus has great success, even killing Zeus's son Sarpedon, but Apollo aids Hector in killing Patroclus. Hector strips Achilles' armour from Patroclus's body, and Book 17 depicts a fierce struggle over the corpse itself. The Greeks eventually recover the body but lose the armour.
Books 18-19: Achilles Returns
Wrath redirected. When Achilles learns of Patroclus's death, his grief is overwhelming. His anger now shifts from Agamemnon to Hectorâhe swears to kill Hector or die trying. His mother Thetis visits Hephaestus, who forges magnificent new armour for Achilles, including the famous Shield of Achilles (described in detail in Book 18). In Book 19, Achilles and Agamemnon publicly reconcile, and Achilles arms himself for battle, despite prophecies that his own death will follow soon after Hector's.
Books 20-21: Achilles' Rampage
Unstoppable fury. Achilles returns to battle like a force of nature. The gods themselves descend to the battlefield, fighting each other. Achilles kills countless Trojans with such savagery that he even fights the river-god Scamander, whose waters are choked with corpses. The Trojans flee back into the cityâall except one.
Book 22: Hector's Death
The hero falls. Hector alone remains outside Troy's walls to face Achilles, despite his parents' pleas to come inside. When he sees Achilles approaching, however, his nerve fails and he runs. Achilles chases him three times around the walls of Troy. Finally, with Athena's help (she tricks Hector into thinking he has support), Achilles kills Hector with a spear thrust to the throat. In his rage, Achilles desecrates Hector's body, dragging it behind his chariot back to the Greek camp. He refuses to return the body for proper burial.
Book 23: Funeral Games
Honouring the dead. Achilles holds elaborate funeral games for Patroclus, with contests in chariot racing, boxing, wrestling, archery, and other sports. This book provides a respite from the violence and shows Greek aristocratic culture. Throughout, Achilles continues to abuse Hector's corpse, but Apollo preserves it from decay.
Book 24: Priam's Ransom
The wrath ends. The gods, disturbed by Achilles' treatment of Hector's body, send Thetis to tell Achilles he must accept ransom for it. That same night, Priam, the elderly king of Troy and Hector's father, makes a dangerous journey to Achilles' tent, guided by Hermes. Priam begs Achilles to remember his own father and take pity. The two enemiesâone who has lost a son, one who has lost a companionâweep together. Achilles' rage finally breaks, and he returns Hector's body. The epic ends with Hector's funeral, and an eleven-day truce to mourn the dead.
