Telemachus seeks advice and guidance from Nestor in Pylos and Menelaus in Sparta on his journey to find information about his father, Odysseus. Both Nestor and Menelaus were allies of Odysseus during the Trojan War and may provide valuable insights into his whereabouts.
Telemachus was Odysseus' son. In the Odyssey, he spends much of the story either travelling in search of his father or staying in Sparta as a guest of King Menelaos, but his official place of residence is the island of Ithaca.
Both Telemachus and Odysseus are aided by Athena in leaving their respective locations to get home to rescue Penelope from the suitors. Both men also sneak back into Ithaca in hopes of surprising the suitors by suddenly reappearing.
