Iliad Study Guide
Everything You Need to Know About Homer's Epic
The Iliad is the oldest surviving work of Western literature — over 15,000 lines composed by Homer around 750 BCE about the final weeks of the Trojan War. It focuses on Achilles' rage and its devastating consequences.
Plot Summary
Achilles withdraws from battle after Agamemnon takes his war prize Briseis. Without Achilles, the Greeks lose ground. Patroclus fights in Achilles' armor and is killed by Hector. Mad with grief, Achilles returns, kills Hector, and drags his body behind his chariot. The poem ends when King Priam begs for his son's body, and Achilles, moved by the old man's grief, returns it.
Major Themes
The central theme is the destructive nature of rage. Honor and glory drive every character, yet the poem questions whether glory is worth its cost. Mortality gives human actions meaning that divine actions lack. The relationship between Achilles and Patroclus — whether read as friendship or love — is the emotional heart of the entire work.
Key Characters
Achilles is the greatest warrior but deeply flawed. Hector is the tragic hero fighting for his family. Agamemnon is a mediocre leader whose arrogance triggers the crisis. Patroclus represents the cost of war.
Book-by-Book Landmarks
The Iliad is divided into 24 books. The division probably comes from scholars in Hellenistic Alexandria, not from Homer. Students are usually expected to know these key episodes:
- Book 1 — Chryses, a priest of Apollo, is refused his daughter, and Apollo sends a plague. Agamemnon takes Briseis, and Achilles withdraws. Thetis persuades Zeus to let the Trojans win in the meantime.
- Book 2 — Agamemnon's false dream, his disastrous test of the army, Thersites, and the Catalogue of Ships.
- Book 3 — Helen names the Greek leaders from the walls of Troy, and Paris duels Menelaus. Aphrodite snatches Paris away before he can be killed.
- Books 4–5 — Pandarus breaks the truce with an arrow. In his aristeia, or moment of glory, Diomedes wounds both Aphrodite and Ares.
- Book 6 — Glaukos and Diomedes discover they are guest-friends and exchange armour. Hector says goodbye to Andromache and their baby, Astyanax, who is frightened by his father's helmet.
- Book 9 — the Embassy: Odysseus, Phoenix and Ajax offer Achilles rich compensation, and he refuses.
- Book 10 — the night raid, called the Doloneia, which many scholars think was added later.
- Book 14 — Hera seduces Zeus on Mount Ida to distract him from the war.
- Book 16 — Patroclus fights in Achilles' armour. He kills Sarpedon, Zeus's son, and is then struck by Apollo, wounded by Euphorbus and finished off by Hector.
- Book 18 — Achilles mourns, and Hephaestus forges the Shield of Achilles, decorated with a city at peace and a city at war.
- Books 20–21 — the gods fight one another, and Achilles battles the river Scamander.
- Book 22 — Hector dies before the walls of Troy.
- Book 23 — Patroclus' funeral and the funeral games.
- Book 24 — Priam visits Achilles at night, guided by Hermes. The poem ends with Hector's funeral.
What the Iliad Does Not Contain
One common exam mistake is to credit the Iliad with the whole Trojan War. The poem covers only a few weeks in the war's tenth year. The Judgement of Paris is mentioned only once, in Book 24. Achilles' death, the Trojan Horse and the sack of Troy are not narrated at all. These episodes belonged to other epics of the lost Epic Cycle (the Cypria, Aethiopis, Little Iliad and Sack of Ilion), known mainly from summaries by a later writer called Proclus. Virgil's Aeneid Book 2 and Quintus of Smyrna's Posthomerica fill in the fall of the city. The poem also never says Achilles could be harmed only in his heel. That idea appears much later, notably in Statius.
Key Terms and Ideas
- Mēnis — "wrath", the poem's first word. It is a word normally used for divine anger, and it signals that Achilles' rage is almost godlike in scale.
- Kleos and timē — glory that lives on in song, and honour measured in prizes and status. Agamemnon's seizure of Briseis is an attack on Achilles' timē.
- Achilles' choice — in Book 9, Achilles says his mother told him of two fates: a short life with undying glory at Troy, or a long, obscure life at home.
- Epithets and formulas — phrases like "swift-footed Achilles" and "rosy-fingered Dawn" are evidence of oral composition. Milman Parry made this argument in the 1920s and 1930s.
- Similes — extended comparisons drawn from farming, weather and hunting. They briefly bring the peaceful world into the battlefield.
Dating remains debated. Most scholars place the poem in the late eighth or seventh century BC, and whether a single poet called Homer existed is the long-running "Homeric Question." Choosing a translation matters too. Richmond Lattimore (1951) is close to the Greek line by line. Robert Fagles (1990) is vivid and popular in classrooms. Stanley Lombardo (1997) is fast and colloquial. Caroline Alexander (2015) and Emily Wilson (2023) are recent, highly regarded versions. For what happens next, see the Odyssey study guide.

Ancient sources
- Homer, Iliad — the primary text, about 15,700 lines of dactylic hexameter.
- Homer, Odyssey 11 and 24 — Achilles' shade in the underworld, and the account of his funeral and the shared urn with Patroclus.
- Proclus, Chrestomathy (summary of the Epic Cycle) — what happened before and after the Iliad, including Achilles' death in the Aethiopis.
- Aristotle, Poetics — praises Homer for building the plot around a single action instead of the whole war.
- Plato, Republic 2–3 — criticises Homer's portrayal of the gods and of Achilles' grief as unfit for educating citizens.
Frequently asked questions
Does the Iliad include the Trojan Horse?
No. The horse is mentioned in the Odyssey (Books 4 and 8) and told in full in Virgil's Aeneid Book 2. The Iliad ends before Troy falls.
Does Achilles die in the Iliad?
No. His death is foretold several times, including by the dying Hector in Book 22, but it happens after the poem ends.
Who kills Patroclus?
Three attackers. Apollo strikes him and knocks off his armour, Euphorbus wounds him with a spear, and Hector gives the fatal blow. Patroclus himself points this out as he dies in Book 16.
How long does the Iliad take to read?
Most translations run 500–600 pages, which is roughly 15–20 hours of reading. Many courses assign Books 1, 6, 9, 16, 18, 22 and 24 as a core selection.
