Iliad, by Homer

The Iliad is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. Like the Odyssey, the poem is divided into 24 books and was written in dactylic hexameter. It contains 15,693 lines in its most widely accepted version. The Iliad is often regarded as the first substantial piece of European literature and is a central part of the Epic Cycle.
Set toward the end of the Trojan War, a 10-year siege of the city of Troy by a coalition of Mycenaean Greek states, the poem depicts significant events in the war's final weeks. In particular, it traces the anger of Achilles, a celebrated warrior, from a fierce quarrel between him and King Agamemnon, to the death of the Trojan prince Hector. The narrative moves between wide battleground scenes and more personal interactions.
Critical themes in the poem include kleos (glory), pride, fate, and wrath. Despite being predominantly known for its tragic and serious themes, the poem also contains instances of comedy and laughter. The poem is frequently described as a "heroic" epic, centred around issues such as war, violence, and the heroic code. It contains detailed descriptions of ancient warfare, including battle tactics and equipment. However, it also explores the social and domestic side of ancient culture in scenes behind the walls of Troy and in the Greek camp. Additionally, the Olympian gods play a major role in the poem, aiding their favoured warriors on the battlefield and intervening in personal disputes.
