This is the oldest preserved piece of goldsmith's work in Midden Limburg, commissioned by Aleidis van Diest priorin of the abbey of Herkenrode founded in 1182. The monstrance is of exceptional importance because it is the earliest example of goldsmith's work on which the brand prescribed by the French King Philip III in 1275 goes a lily. The sacramento of Herkenrode is undoubtedly one of the oldest eucharistic relic costories in which miraculous hosts or wine that transformed into the blood of Christ were shown to pilgrims for worship and from which typologically the monstrance developed in a later stage. The monstrance of herkenrode has received special admiration since 1317 and as such is important for the collective memory.
