In 1317 at Viversel in present-day Belgian Limburg, a priest carrying Viaticum to a dying woman opened the pyx to find the consecrated host visibly bleeding, soaking the small linen on which it rested. The bishop of Liège opened a formal inquiry; the relic was confirmed and given to the Cistercian abbey of Herkenrode for safe-keeping.
After the suppression of Herkenrode in 1796, the relic was translated to the Cathedral of Saint-Quentin in Hasselt, where it remains. The septennial Procession of the Holy Sacrament (every seventh year) draws great crowds through the streets of Hasselt.
