This is where the Odyssey begins. Right after Odysseus wins the Trojan War, he and his men head to Cicones to gather more food, materials, and riches but it ends up costing 216 men their lives. This sets off the main course of events that Odysseus goes through.
As Odysseus is on his journey home, he sees an island and decides to go visit it. It happens to be the home of a cyclops named Polyphemus that traps him in his cave and ends up killing a few of Odysseus's men. They finally escape by poking the cyclops in his eye and hiding under sheep.
After Odysseus escapes the cyclops, they visit Aeolia, the god of wind. She gives Odysseus a bag of west wind to help him get home. He does not tell his crew what is in the bag so they get curious and open the bag which releases the wind and makes it more difficult to get home.
Odysseus sends his men to look for food and water and they hear Circe singing so they go to her and she turns them into pigs. When Odysseus shows up he persuades her to turn them back into humans and they end up staying with her around a year.
After Odysseus visits the Land of the Dead, passes the sirens, and kils Helios's cattle, he is caught in a storm that destroys his ship and kills all of his men, he starts drifting towards Charybdis but saves himself by hanging on to a tree branch.
After ten years at war and ten years at sea, Odysseus finally returns back home to Ithaca where he is disguised as a beggar to see if his wife and son remained loyal to him. Once he confirmed that they stayed loyal, he told them who he was and he killed all the suitors that tried to marry his wife and kill his son.
