In this epic poem, Antinous is depicted as the most agressive of Penelope's suitors and; therefore, of Odysseus' rivals together with Poseidon, also known as the Earth-shaker. However, in The Odyssey there are also characters who act as companions and advisors such as Athena, who takes the disguise of Mentor, and Pisistratus, who is Nestor's son and Telemachus' friend. Moreover, Menelaus, Helen's husband, also appears in this poem and refers to his journey back home after the Trojan War.
