Pierronne, also called "Perrinaïc", was a 15th-century Breton woman who said she saw visions of "God dressed in a long white robe with a red tunic underneath". She came into contact with Joan of Arc in 1429, tried to publicly defend Joan's reputation at Corbeil where Pierronne was arrested in March of 1430 and burned at the stake on 3 September 1430.
