Ep. 1047 - Legends of the Rhine - The Arrow at Prüm

It was in the little town of Prüm many a long year ago that Lothaire, the degenerate son of St. Louis, did penance for his sins. In the church belonging to the town there are two very ancient pictures; one of them represents a knight standing on a huge rock, shooting an arrow, while his wife and retinue are looking devoutedly towards heaven; the other represents a priest at an altar to whom an angel is bringing an arrow.

Who is the knight?

Who is the holy man?
