The River of Forgetfulness

Near is thy forgetfulness of all things, and near the forgetfulness of thee by all. Marcus Aurelius.  Meditations.  Book 7.

Lethe, the river of forgetfulness, is one of the five rivers of the Greek underworld. The other four are Acheron (the river of sorrow), Cocytus (the river of lamentation), Phlegethon (the river of fire) and Styx (the river that separates Earth and the Underworld). According to Statius, it bordered Elysium, the final resting place of the virtuous. Ovid wrote that the river flowed through the cave of Hypnos, god of sleep, where its murmuring would induce drowsiness. The shades of the dead were required to drink the waters of the Lethe in order to forget their earthly life. In the Aeneid, Virgil (VI.703-751) writes that it is only when the dead have had their memories erased by the Lethe that they may be reincarnated.

Amongst authors in antiquity, the tiny Lima river between Norte Region, Portugal, and Galicia, Spain, was said to have the same properties of memory loss as the legendary Lethe River, being mistaken for it. In 138 BCE, the Roman general Decimus Junius Brutus Callaicus sought to dispose of the myth, as it impeded his military campaigns in the area. He was said to have crossed the Lima and then called his soldiers from the other side, one by one, by name. The soldiers, astonished that their general remembered their names, crossed the river as well without fear.
