The River of Forgetfulness

Hesiod names Lethe — Forgetfulness — as a daughter of Eris, but in the geography of the underworld she is a river. Five rivers flow through the realm of the dead, and Lethe is the last. Where Styx binds and Phlegethon burns, Lethe erases. Its waters wipe the memories of the dead clean. In Ovid, the river flows past the cave of Hypnos, where its murmuring over pebbles lulls the god of sleep himself into drowsiness.

The Plain of Lethe

Souls who had completed their judgment and chosen their next lives were led to the Plain of Lethe, a barren expanse beneath terrible heat. They camped beside the River of Forgetfulness, whose water no vessel could hold. Each soul drank a measure, and those not saved by wisdom drank more than necessary. As they drank, they forgot everything. At midnight, thunder and earthquake scattered them upward like shooting stars to their new births. Only the soldier Er, in Plato's telling, was forbidden to drink. He returned to the living with his memories intact.

Memory against Oblivion

The Orphic gold tablets told the dead a different story. These thin inscribed leaves, buried with initiates across southern Italy, instructed the soul to avoid the spring on the left side of the underworld house, where a white cypress stands. Instead, the soul should seek the spring of Mnemosyne on the right, guarded by sentinels, and declare: "I am a child of Earth and starry Heaven. I am parched with thirst and I perish. Give me cold water from the Lake of Memory." By drinking from Memory's waters and reciting the correct passwords, the initiated soul could escape the cycle of rebirth.

At the oracle of Trophonius in Lebadeia, this same pairing was enacted among the living: consultants drank first from Lethe to forget their worldly concerns, then from Mnemosyne to remember what they would experience in the prophetic cave below.
