Theia Mania

Lamia (plural: lamiai) and Mormo (plural: mormones) were some kind of female ghosts or demons who attacked women and children. They were said to once have been mortal women who killed their own children. Besides from explaining why babies sometimes died, their stories also served as a reminder to Greek girls that their success in life would be defined by their reproductive accomplishments. According to Restless Dead by Sarah Iles Johnston, “Refusal or failure to perform would place them in the same relationship to society as Lamia, Gello, and Mormo and would lead to their suffering the same unhappy sort of afterlife”.
