The work comprises 15,693 verses in 24 cantos, marked with capital Greek letters according to the standard alphabet of Eukleides in 403 BC; the length of the books varies roughly between 400 and 900 verses.
The wrath motif that pervades the entire epic, however, comes to the fore more strongly in only a few of the 24 books. Achilles' anger is developed by Agamemnon's dishonour for robbing his prey-girl Briseïs in order to make an example of his power on him. Achilles bows to this and goes on strike and thus into the background of the Iliad. Thus, in the 2nd through 8th books, the narrator is able to incorporate scenes from earlier years of the war and depict a first meeting of the warring parties. It is not until the 9th book that Achilles is addressed again, as the other Achaians have realized that they cannot stand against the Trojans without him and his comrades-in-arms. However, since Agamemnon does not want to apologize for his misbehavior and Achilleus' anger is still too great, he refuses to compromise and thus not only opposes Agamemnon, but also the other Achaians. He thereby decides the death of many companions, since Zeus grants the Trojans to reach the ship's camp of the Achaians. Only after that the battle shall be turned. Until this happens, the story is retarded by the depiction of the battles around the wall in front of the ships and by divine interventions in favour of the Achaians.
In the 16th book, Zeus' plan is fulfilled, so that Achilles grants Patroclus to push back the Trojans. However, he then attacks the city in high spirits and is killed by Hector, among others. The ensuing struggle over the latter's body and the production of new weapons point to the following books. Achilles, horrified at the loss of his friend, then reconciles with Agamemnon in the 19th book and, still angry but now at Hector, charges into battle. Until the final battle with the latter in the 22nd book, however, he fights several other opponents and even gods. The final overcoming of his anger then takes place only after the mistreatment of Hector's corpse and death games for Patroclus' cremation in the 24th book. To do this, he must first meet the father of his arch-enemy - Priam - who, like Achilles, has suffered a heavy loss.
