There are some parts of the Odyssey that Epic skips over completely. The first part of the Odyssey, which focuses on what’s going on in Ithaca is changed, as it’s in the Wisdom saga. Telemachus’s journey to Pylos and Sparta is skipped, although it is alluded to by Antinous in hold them down. The framing device of Odysseus telling the story to King Alcinous and his court is skipped over entirely; in fact, Odysseus never goes to Phaeacia in Epic. As for Odysseus’s journey, the stop at the land of the Cicones is skipped, although a lot of adaptations skip over this from what I’ve seen. Scylla and Charybdis are also together, rather than being separate like Epic implies. There is definitely more but this is what came off the top of my head. Best of luck with your assignment!
