Chichevache
The Chichevache is a mythological European monster fabled to feed on good women.
In Geoffrey Chaucer's Canterbury Tales, this human-faced cow is perpetually starved to skin and bone due to the scarcity of obedient and faithful wives. The Bicorne or Bycorne, a counterpart to the Chichevache which fed on obedient and kind husbands, was reputedly fat and plump because of the plentiful supply of such men.
