Who Is Hermes In The Odyssey?

After the war, Odysseus tries come back to Ithaca, but ends up captured by Calypso, a nymph, in her island. As Calypso is possessed with her affections for Odysseus, she forbids him from ever leaving her. Odysseus continues to despair at thought of him never returning back home, with him being trapped by Calypso and with nothing as a means for his escape as currently, he has no ship and no crew.
In an assembly in Mount Olympus the Gods have decided to aid Odysseus. Zeus then sends his son, Hermes, Messenger of the Gods, to rescue Odysseus from Calypso’s imprisonment. As Hermes arrives, he convinces Calypso to have a ship built for Odysseus and to let him leave. Odysseus then leaves and set sails home. But when the God of the Seas, Poseidon, discovers him sailing back to his home, Poseidon decides to send out a massive storm to damage Odysseus’ ship as revenge for the earlier deed Odysseus’ did to him in the form of blinding Polyphemus, who is a cyclops and one of Poseidon’s sons. Athena then comes and saves Odysseus from Poseidon’s wrath. He then safely arrive at Scheria, where upon introducing himself he recieves a hospitable treatment from his hosts and a promise of safe passage to Ithaca in exchange of him regaling his tales to them.
Odysseus then spends the rest of the night regaling them of his adventures in the war, to the Lotus Eaters, to his battle and ouwitting of Polyphemus, to how dangerous were the sirens, to his imprisonment on Calypso’s island, and of how Hermes helped him get up all the way to how he arrived here.
