I suppose this could be. I was just curious because she is listed in Classical Roman Mythology:
The protecting deity of ancient Rome and a goddess of secrecy and of the winter solstice. Angerona is shown with a bandaged mouth with a finger to her lips commanding silence. Her feast -- the Divalia or Angeronalia -- was celebrated on December 21.
I wondering because for my Latin class I was considering doing her for a classical Roman mythology mask.
