 A perhaps apocryphal story from a Cistercian chronicle "circa" 1200 indicates that the viaticum was regarded as an apotropaic seal against demons ("ad avertendos daemonas"), who nevertheless induced a woman to attempt to snatch the Host ("viaticum") from the mouth of Pope Urban III's corpse.Like Charon's obol, the viaticum can serve as both sustenance for the journey and seal.In the 19th century, the German scholar Georg Heinrici proposed that Greek and Roman practices pertaining to the care of the dead, specifically including Charon’s obol, shed light on vicarious baptism, or baptism for the dead, to which St. Paul refers in a letter to the Corinthians.
