 This blood was subsequently collected into a reliquary and is placed on the Chapelle des "Trois Gouttes de Sang"'s altar, along with the tablecloth and along with Jesus' head from the crucifix which had been broken off by French revolutionaries when they desecrated the cathedral.This head has in fact been carefully analysed and dates to the 12th-century.Hirsch's stained glass window in this chapel dates to 1869 and depicts the friend's act of perjury before the knight and his wife, a bishop and judges.
