Katabasis

A katabasis or catabasis (Ancient Greek: κατάβασις, romanized: katábasis, lit. 'descent'; from κατὰ (katà) 'down' and βαίνω (baínō) 'go') is a journey to the underworld. Its original sense is usually associated with Greek mythology and classical mythology more broadly, where the protagonist visits the Greek underworld, also known as Hades. The term is also used in a broad sense of any journey to the realm of the dead in other mythological and religious traditions. A katabasis is comparable to a nekyia or necromancy, where one experiences a vision of the underworld or its inhabitants; a nekyia does not generally involve a physical visit.

One of the most famous examples is that of Odysseus, who performs something on the border of a nekyia and a katabasis in book 11 of the Odyssey; he visits the border of the realms before calling the dead to him using a blood rite, with it being disputed whether he was at the highest realm of the underworld or the lowest edge of the living world where he performed this.

The trip to the underworld is a mytheme of comparative mythology found in a diverse number of religions from around the world. The hero or upper-world deity journeys to the underworld or to the land of the dead and returns. The nature of the quest differs; sometimes an object or the rescue of a loved one is sought, while in other stories knowledge and secret revelations is the goal. The ability to enter the realm of the dead while still alive, and to return, is proof of the classical hero's exceptional status as more than mortal. A deity who returns from the underworld demonstrates eschatological themes such as the cyclical nature of time and existence, or the defeat of death and the possibility of immortality.

A katabasis is arguably a specific type of the famous Hero's journey. In the Hero's journey, the hero travels to a forbidden, unknown realm; a katabasis is when that place is specifically the underworld. Pilar Serrano uses the term to encompass brief or chronic stays in the underworld as well, such as those of Lazarus, and Castor and Pollux.

A katabasis is in general followed by an anabasis (a going up) to distinguish itself from death; very rarely does a living hero decide to stay in the Underworld forever.

Famous examples of katabases in Greek mythology include Orpheus, who enters the underworld in order to bring Eurydice back to the world of the living, and Odysseus, who seeks to consult with the prophet Tiresias for knowledge. In Roman mythology, Aeneas seeks out his father Anchises to learn of prophecies of his fate and that of the Roman Empire.

In the 11th book of the Odyssey, Odysseus follows the advice of Circe to consult Tiresias in Hades, the land of the dead. Odysseus sets out an offering of honey, milk, wine, water, and barley before slaughtering two sheep to add fresh blood to the meal. The souls of many then appear to him. The first to appear to Odysseus is Elpenor, his crew member who died prior to leaving Circe's island. Elpenor asks Odysseus to give him a proper burial, and Odysseus agrees. The next to appear to Odysseus is his mother, Anticlea. As Odysseus has been away fighting the Trojan War for nearly 20 years, he is surprised and saddened by the sight of her soul.

Tiresias, the soul whom Odysseus came to see, next appears to him. Tiresias gives him several pieces of information concerning his nostos (homecoming) and his life hereafter. Tiresias details Poseidon's anger at Odysseus' blinding of Polyphemos (and the coming troubles as a consequence), warns Odysseus not to eat the livestock of the god Helios, and prophesies Odysseus' return home to Ithaca and his eventual death at sea at an old age. After Tiresias instructs Odysseus to allow the spirits he wants to talk to drink the sacrificial blood he used to find Tiresias, he is again given the chance to see his mother, and she tells him of the suffering of his family as they await his return home. As his mother leaves, Odysseus is then visited by a string of souls of past queens. He first sees Tyro, the mother of Pelias and Neleus by Poseidon.
