The Odyssey consists of twenty-four books, and is a sequel to the Iliad. The story of the Odyssey starts when Troy has been destroyed and the Trojan War has come to an end. It creates a new epic with the adventure story of the Greek hero Odysseus who is struggling to go back to his home after the Trojan War. His journey combines hopes and hopelessness, loyalty and disloyalty, hospitality, vengeance, intelligence, experience, and what it means to be mortals and to be gods. During his entire journey, the gods play an important role. Interestingly, sometimes some of the gods help him, and sometimes some of the gods, like Poseidon, who are not happy with him, create trouble for him. Thus, his journey becomes a matter of argument between the gods.
