Our friend Bird Dog from Maggie’s Farm linked the video below, featuring the 2004 annual procession in the Umbrian city of Orvieto celebrating the 1263 Miracle of Bolseno, in which a communion host produced blood during the moment of consecration of the mass, affirming the Roman Catholic doctrine of transubstantiation.
The procession carries the corporal of Bolseno (the small cloth on which the host rested during the consecration) through the city of Orvieto on the Feast of Corpus Christi, the Thursday following Trinity Sunday, the date on which the Catholic Church celebrates the institution of the Holy Eucharist.
The feast day was created in 1264 by Pope Urban IV, reputedly on the basis of the inspiration of the miracle of Bolseno.
In any event, the procession is a remarkable spectable and a marvelous survival of an ancient European tradition. What an extraordinary number of groups and organizations Orvieto seems to possess!
