The gods, heroes, and monsters of ancient Greece come from a body of stories that were religion before they were literature, passed down orally for generations before anyone wrote them down. The film traces how those accounts survive today: Homer's Iliad and Odyssey centering on the Trojan War, Hesiod's Theogony laying out the succession of divine rulers from Chaos to Zeus, and later writers like Plutarch and Pausanias recording variants under the Roman Empire. Scholars and experts walk through how vase paintings and votive offerings carried the myths visually long before literary texts did, pointing to geometric pottery from the eighth century BC that already depicts the Trojan cycle and the labors of Heracles. The film also tracks the myths forward, showing how Zeus, Athena, and Odysseus resurface centuries later in Shakespeare, Milton, and the sculpture of Michelangelo and Rodin. Its case is that Greek mythology never functioned as simple entertainment, but as an explanation for the origin of the world and the behavior of the people who told these stories about themselves.
