Saint Ursula was a king’s daughter (4th/5th century) who was murdered together with several virgins in Cologne. Possibly due to an interpretation error of the legend the cult changed to ‘Saint Ursula and the eleven thousand virgins’ in the ninth century. This legend received renewed attention thanks to the discovery of the pseudo-relics in 1106 in Cologne. An enormous export of these bones on a large scale was a logical consequence. The above article presents a status quaestionis of the relics and relic treasures of these virgins preserved in the Belgian province of Limburg. The focus lays on the bones, which have been subject to extensive material technical studies in recent years. These relics can be found in Sint-Truiden, Tongeren, Hasselt, Kerniel, Borgloon and Maaseik. They are related to a cult that was already established in the Middle Ages and continued to be valued over the centuries. The researched cult objects can mostly be found around Sint-Truiden. Willem van Ryckel (1249-1272), abbot of the Saint Trudo Abbey, was a great promoter of the cult. Material-technical analysis proves that all relic treasures contain ancient human bones. Exceptionally, animal bone material is also found. Over the centuries, the relics were decorated with many textile fragments. Pieces of old (rich) textiles were repurposed and added to the relics. Because the textiles touched the relics, they acquired a sacred status themselves, so they could no longer be removed from the skulls or bones. The art-historical and material-technical analyses clearly indicate that they came from far and wide. This gives evidence to the then existing trade networks. The many layers of cloth added over centuries show how much the relics of Saint Ursula and the Elven Thousand Virgins were appreciated. This attests to the historical value of the relics.
