The Iliad and the Odyssey, written in the 9th century BC and attributed to Homer, are among the oldest surviving pieces of literature from ancient Greece, and are often considered the beginning of European literary canon. The stories contain supernatural elements such as gods and monsters, but also realistic details about warfare and daily life in pre-classical Greece.

The Iliad describes the Achaeans' ten-year siege of Troy, omitting both the beginning and the conclusion of the war. The Odyssey describes Odysseus' (Ulysses in Latin) disastrous ten-year journey back to his hometown Ithaca, making landfall at many places around the Mediterranean. Some of those locations can be identified in the real world, but in Hellenistic Greece, others were either forgotten or dismissed as fictional. Some famous tropes of the Trojan war, such as the abduction of Helen the Fair and the Trojan horse, are absent from the Iliad, and mentioned briefly in the Odyssey.

The Aeneid, written by Virgil in the 1st century BC, retells the war through the Trojan hero Aeneas and describes him migrating to Italy, becoming an ancestor of the Romans.

The epics describe the abduction of Helen, wife of Menelaus the king of Sparta, by Paris, a Trojan prince, sparked enmity between the Trojans and the Achaeans from across the Aegean Sea. Having been unable to break into the defensive walls of the city, the Achaeans decided to set up a trick—they offered a huge wooden horse as a gift to the Trojans, as amends for the bother they caused with their war galleys on the city's beach. The Trojans accepted the offer sincerely, but this resulted in them losing their city, as inside of the horse were of Achaean soldiers, ready to fight, and now right in the centre of the city.
