What you definitely need to know before going to Nolan's "Odyssey" in the cinema?

Homer's "Odyssey," an epic poem likely composed in the 8th century BCE, remains one of the foundational works of Western literature. Originally presented in 24 songs and nearly twelve thousand dactylic hexameters, its authorship is attributed to Homer, though his historical existence is debated. The poem likely evolved through oral traditions before being transcribed.

The narrative unfolds ten years after the decade-long Trojan War, itself sparked by the abduction of Helen. The main plot covers about 40 days, but through numerous flashbacks, it recounts Odysseus's arduous journey home. He faces trials, including being held captive by the nymph Calypso, before Athena intervenes with Zeus's consent.

A significant complication in Odysseus's return to Ithaca, his wife Penelope, and son Telemachus is his blinding of the cyclops Polyphemus, son of Poseidon. This act incurs the sea god's wrath, hindering Odysseus's journey for years. The poem also explores the ancient Greek concept of "xenia," or hospitality, where guests were first fed and cared for before their identities were revealed.

Penelope's situation, hosting numerous suitors who consume Odysseus's estate while he is away, is a central tension. Her cleverness is shown in her delaying remarriage by promising to wed after weaving a shroud for Laertes, only to unravel it each night. Throughout his journey, Odysseus receives crucial support from the goddess Athena, who advocates for his return and aids both him and Telemachus in their struggles.
