The Ghost Marge Simpson character half masks is a redesign of a commedia mask in the collection. A major theme in the commedia is death but this is not why there is a Ghost Marge. She appears this way in act 3 of Mr. Burns a post electric play.
Ghost Marge is the dead archetype of the conservative housewife. Death is not ordinary so she is not a fan and it seems also unnecessarily exotic… aside form the fact that’s its devoid of life of any kind. Death is odd like that.
It might be added here (since we started with references to the commedia dell’Arte) that death can also be a theme for lazzi and therefore morbidly entertaining. Could be the origin of, “to die laughing.”
