How did Odysseus and his mean reach the land of the dead?

Odysseus and his men reached the land of the dead, known as the Underworld, after following the instructions of the sorceress Circe. She advised him to sail to the shores of the Underworld and perform a ritual involving the sacrifice of animals, allowing the spirits of the dead to appear. With the help of the god Hermes, Odysseus and his crew successfully navigated to this eerie realm to seek guidance from the prophet Tiresias. This journey was crucial for Odysseus to gain insights about his return home to Ithaca.
