The
Nekromanteion was an ancient Greek temple of
necromancy devoted to Hades and
Persephone. According to tradition, it was located on the banks of the
Acheron river in
Epirus, near the ancient city of
Ephyra. This site was believed by devotees to be the door to
Hades, the realm of the dead. The site is at the meeting point of the Acheron,
Pyriphlegethon and
Cocytus rivers, believed to flow through and water the kingdom of Hades. The meaning of the names of the rivers has been interpreted to be "joyless", "burning coals" and "lament."
