Overview

Acheron serves different but compatible geographic roles in two sources. In Odyssey 10, Circe directs Odysseus to the place where Pyriphlegethon and Cocytus flow into Acheron and tells him to perform the rite by the rock. In the later Bibliotheca, Heracles finds Cerberus by the gates of Acheron. The first is the route to Odysseus’ consultation; the second belongs to a heroic labour. The two passages keep their own settings without using a shared river name to expand the two narratives into one complete universal map.
