Wilgefortis is a female fictitious saint of popular religious imagination whose cult arose in the 15th century. Her name derives from the Old German "heilige Vartez" ("holy face"), a translation of the Italian "Volto Santo". The "Volto Santo" of Lucca (picture:Volto Santo) is an early Byzantine iconic image depicting a bearded — but androgynous — Christ crowned and crucified and dressed in a full-length tunic, instead of the normal loin cloth.
