Step-by-step explanation:
In Book 3 of The Odyssey, Nestor tells the story of Agamemnon's fate. According to Nestor, Agamemnon was the king of Mycenae and the leader of the Greek forces in the Trojan War. After the war, Agamemnon returned home to find that his wife, Clytemnestra, had taken a new lover and murdered him in revenge for his sacrifice of their daughter, Iphigenia. Agamemnon's fate serves as a warning about the consequences of betrayal and vengeance.
With respect to what happens in Ithaca, the story of Agamemnon's fate parallels the situation in Odysseus' home. Like Agamemnon, Odysseus has been absent from home for many years, and his wife, Penelope, is courted by a group of suitors who are wasting his wealth and plotting against his son, Telemachus. The story of Agamemnon serves as a foreshadowing of the dangers that await Odysseus when he returns to Ithaca.
