The Five Rivers of Hades in Greek Mythology

In Greek mythology, the Underworld features five rivers: Styx, Acheron, Pyriphlegethon, Kokytos, and Lethe. The Styx, an Oceanid daughter of Titans Okeanos and Tethys, forms the boundary of Hades and is used for divine oaths. Charon ferries souls across it, though some sources connect him to the Acheron. The Acheron, a real river in Epirus, Greece, also serves as an entrance to the Underworld, with the Necromanteion temple nearby. The Pyriphlegethon, a river of fire and boiling mud, flows into Tartarus, vividly described by Virgil. The Kokytos, river of lamentation, is a branch of the Styx; in Dante's Inferno it becomes a frozen lake in the ninth circle of Hell. The Lethe, river of forgetfulness, is associated with reincarnation in Plato and appears in Virgil's Aeneid as a pleasant stream. Other rivers like Okeanos, Alpheus, and Arethusa also connect to the Underworld. These rivers represent justice, mortality, memory, and the boundary between life and death.
