"Royal son of Laertes, Odysseus, old campaigner,
stay on no more in my house against your will.
But first another journey calls. You must travel down
to the House of Death and the awesome one, Persephone,
there to consult the ghost of Tiresias, seer of Thebes,
the great blind prophet whose mind remains unshaken.
Even in death – Persephone has given him wisdom,
everlasting vision to him and him alone…
the rest of the dead are empty, flitting shades."
– Homer
The Odyssey, Book 10, lines 537-545. When Odysseus asks Circe for help in getting home, the immortal goddess tells him that he must first make a journey to the underworld. She tells him that he needs to consult there with the ghost of Tiresias, the blind Theban prophet.
