Henry III, Holy Roman Emperor
The bodies of Monulph and Gondulph were solemnly exhumed in 1039 by Bishop Nithard of Liège and Gerard of Florennes, Bishop of Cambrai, in the presence of Henry III, Holy Roman Emperor. An epitaph commemorating this event was later misinterpreted, giving rise to a legend according to which the two saints arose from their tomb in 1039 in order to assist at the dedication of Aachen Cathedral.
