In Egyptian mythology, Taweret (also spelt Taurt, Tuat, Taueret, Tuart, Ta-weret, Tawaret, an Taueret, and in Greek, Thoeris and Toeris). Her name means (one) who is great. She was originally the demon-wife of Apep, the original god of evil. Since Apep was viewed as residing below the horizon, and only present at night, evil during the day was envisaged as being a result of Taweret's maleficence.
