 The custom of Charon’s obol not only continued into the Christian era, but was adopted by Christians, as a single coin was sometimes placed in the mouth for Christian burials.At Arcy-Sainte-Restitue in Picardy, a Merovingian grave yielded a coin of Constantine I, the first Christian emperor, used as Charon’s obol.In Britain, the practice was just as frequent, if not more so, among Christians and persisted even to the end of the 19th century.
