1. The odyssey finale

2. “20 years gone and I am back again”
Athena casts a protective mist on Odysseus that keeps him from recognizing his homeland. Athena reveals herself and dispels the mist. In joy, Odysseus kisses the ground. Athena transforms him into a beggar as a disguise. In his filthy tunic, he goes off to fins his faithful swineherd, as instructed by the goddess. Meanwhile, numerous suitors are overrunning Odysseus’s palace. Moreover, they are plotting to kill his son, Telemachus. Athena also tells Telemachus how to avoid ambush from the suitors.

3. Telemachus recognizes his father
Telemachus evades the suitors’ ambush. Following Athena’s instructions, he proceeds to the farm of Eumaeus. There he sees the old beggar and makes acquaintance with him. Athena restores Odysseus’ normal appearance, enhancing it so that Telemachus thinks that he is a God. “No god am I, but your own father, returned after 20 years.” Later they plot how to avenge the suitors with the help of the Gods.

4. penelope
Odysseus has a long talk with Penelope who does not recognize him in his beggar costume. Penelope orders his maid to show hospitality by bathing the beggar’s feet with oil. They notice a scar on his knee that Odysseus has had since he was a child. The maid recognizes him at once but Odysseus silences her quickly.
Odysseus asks for a sign from Zeus who sends a clap of thunder down.

5. The suitors and Odysseus’ revenge
Penelope gives her suitors a test to string Odysseus’ best bow. “whoever strings this bow and sends an arrow straight through the sockets of twelve axe heads lined in a row, will be the man I will marry.”
Still disguised, Odysseus tries the test and succeeds in winning.
Telemachus, Athena, and Odysseus kill off all of the suitors.

6. Penelope’s test
When Odysseus sits down beside Penelope that night, she tells him that he can sleep outside her room, on the bed that Odysseus carved years ago.
At this point Odysseus snaps, asking who dared move his bed. Apparently, he built the entire bedroom around a huge olive tree and carved the bed straight from the roots, so it totally can't be moved.
This is the secret that Penelope referenced earlier; she rushes into Odysseus's arms in tears and begs his forgiveness.
The two rejoice, make love, and exchange stories of the twenty long years.
