Exposition
The Odyssey begins ten years after the end of the ten-year Trojan War, and Odysseus has still not returned home from the war. Odysseus' son Telemachus is about 20 years old and is sharing his absent father’s house on the island of Ithaca with his mother Penelope and a crowd of 108 boisterous young men, "the Suitors", whose aim is to persuade Penelope to marry one of them, all the while enjoying the hospitality of Odysseus' household and eating up his wealth.
Odysseus’ protectress, the goddess Athena, discusses his fate with Zeus, king of the gods, at a moment when Odysseus' enemy, the god of the sea Poseidon, is absent from Mount Olympus. Then, disguised as a Taphian chieftain named Mentes (otherwise known as “Mentor”), she visits Telemachus to urge him to search for news of his father. He offers her hospitality; they observe the Suitors dining rowdily while the bard Phemius performs a narrative poem for them. Penelope objects to Phemius' theme, the "Return from Troy"[5] because it reminds her of her missing husband, but Telemachus rebuts her objections.
That night Athena, disguised as Telemachus, finds a ship and crew for the true Telemachus. The next morning, Telemachus calls an assembly of citizens of Ithaca to discuss what should be done with the suitors. Accompanied by Athena (still disguised as Mentor), he departs for the Greek mainland and the household of Nestor, most venerable of the Greek warriors at Troy, now at home in Pylos. From there, Telemachus rides overland, accompanied by Nestor's son, Peisistratus, to Sparta, where he finds Menelaus and Helen, now reconciled. He is told that they returned to Sparta after a long voyage by way of Egypt. There, on the island of Pharos, Menelaus encountered the old sea-god Proteus, who told him that Odysseus was a captive of the nymph Calypso. Incidentally, Telemachus learns the fate of Menelaus’ brother
