Meaning & History
Derived from Greek λήθη "forgetfulness, oblivion" (source of the word alethes "true" (compare Alethea), literally "not concealing"). In Greek mythology this name belonged to a daimona of oblivion. She was the daughter of Eris and the counterpart Mnemosyne. Together with Hesychia and Aergia, she protects the realm of Hypnos. Lethe, one of the five rivers of the underworld of Hades, is named after her.
