Explanation:

Mary just bought two ashtrays.

At Pylos, Telemachus and Mentor (Athena in disguise) witness an impressive religious ceremony in which dozens of bulls are sacrificed to Poseidon, the god of the sea. Although Telemachus has little experience with public speaking, Mentor gives him the encouragement that he needs to approach Nestor, the city’s king, and ask him about Odysseus. Nestor, however, has no information about the Greek hero. He recounts that after the fall of Troy a falling-out occurred between Agamemnon and Menelaus, the two Greek brothers who had led the expedition. Menelaus set sail for Greece immediately, while Agamemnon decided to wait a day and continue sacrificing on the shores of Troy. Nestor went with Menelaus, while Odysseus stayed with Agamemnon, and he has heard no news of Odysseus. He says that he can only pray that Athena will show Telemachus the kindness that she showed Odysseus. He adds that he has heard that suitors have taken over the prince’s house in Ithaca and that he hopes that Telemachus will achieve the renown in defense of his father that Orestes, son of Agamemnon, won in defense of his father.
