Pierronne 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 . Origins . Pierronne was said to have come from western Brittany ( " Bretagne bretonnante " ) , but her exact date and place of birth are unknown . The variant name " Perrinaïc " is an attempt to render the French name " Pierronne " / " Perrine " into Breton with the affectionate suffix " - ic " . Adult life . Not much is known about her life aside from brief descriptions in a couple 15th century sources . She was described as a companion of a Franciscan friar named Brother Richard , who was known for his association with several mystics and visionaries including Joan of Arc , and was a favorite preacher of Charles VII ' s queen , Marie d ' Anjou . Brother Richard had first met Joan of Arc at the city of Troyes in early July 1429 , but the 15th century sources make no mention of Pierronne ' s presence at that time . Anatole France thought that Pierronne " had followed [ Joan ] on her departure from Sully " , but the only certainty is that she was with Joan during Christmas of 1429 since the later accusations against her mention both Pierronne and Joan receiving the Eucharist ( communion ) from Brother Richard at that time . Arrest and execution . Pierronne was among a group of women who tried to defend Joan of Arc ' s reputation by publicly proclaiming that Joan " was good , and that what she did was well done and according to God ' s will . " Pro - English authorities arrested Pierronne and the other women at Corbeil in March of 1430 . She was taken to English - occupied Paris and put on trial by clergy from the city ' s university . Threatened with summary execution unless she recanted , she was burned at the stake on 3 September 1430 . The stated reason given for the execution was her assertion that God appeared to her " dressed in a long white robe with a scarlet tunic " and " she was never willing to revoke her affirmation that she often saw God dressed in this manner , for which reason she was judged to be burned on that day . " Since this is a rather curious accusation , modern historians have speculated that the actual reason for her conviction must have been her statements in support of Joan of Arc : as Pierre Lanéry d ' Arc commented , " Perrinaïc had affirmed on a number of occasions Joan ' s virtues and divine mission : and the English , out of anger , condemned her to die and burned her alive . " Modern literature . Although there isn ' t much literature about Pierronne / Perrinaïc , one of the most influential modern works was a novel written in 1891 called " Perrinaïc , une compagne de Jeanne d ' Arc " by the poet Narcisse Quellien . The historian Henri Daniel - Lacombe commented that Quellien invented almost every detail from his own imagination : " History shows us Pierronne meeting with Joan on only a single day . The poet Quellien places Perrinaïc in Joan ' s company every day or very nearly so , following her right into battle and , ' after the carnage had ended , weeping with her over the dead ' , although once again history doesn ' t attribute a single war - related deed to Pierronne " .
