Hell (Rivers of)
.Classic authors tell us that the Inferno is encompassed by five rivers: Achěron, Cocȳtus, Styx, Phlegěthon, and Lethē. Acheron from the Greek achos-reo, grief-flowing; Cocytus, from the Greek kõkuo, to weep, supposed to be a flood of tears; Styx, from the Greek stugěo, to loathe; Phlegethon, from the Greek phlěgo, to burn; and Lethê, from the Greek letlē, oblivion.
