This is the story of Odysseus (or as the Romans would later call him Ulysses) written by Homer in the time of ancient Greece. The story of Odysseus has been retold many times over the years and is an important element in both the study of Ancient Greece and in literature as well.
This explains to the students more about Homer and his importance to both Greek history and culture. The film also tries to prove that the Trojan war actually took place.
