St. Barbara by Jan Van Eyck. Barbara, daughter of a rich pagan, was kept locked up in a tower by her father. Having secretly become a Christian, she rejected a marriage offer that she received through him. Dragged before the prefect of the province, who had her cruelly tortured, Barbara held true to her faith. Finally she was condemned to death by beheading. Her father carried out the sentence. As punishment for this, he was struck by lightning on the way home and his body consumed by flame.
