Synopses of Book III and IV ( poseidon64.tripod.com/Odyssey.html )
The next morning the ship arrives at the mainland of Pylos; Telemachus and the disguised goddess take part in a hecatomb(?) to the ocean god Poseidon.

King Nestor tells numerous stories about the battles and the return of other heroes at Troy, but knows nothing of the great Odysseus. Athena vanishes into thin air. Nestor is impressed that Prince Telemachus is being helped by the gods, and sends his own son, Peisistratus, to accompany Telemachus on a trip to Sparta to visit King Menelaus and Helen.

The two young men are entertained by the King Menelaus and Queen Helen, who tell of the times with Odysseus in the battles at Troy.
