01
A priest on the road
The cathedral of Orvieto recounts that a Bohemian priest celebrating Mass in Bolsena saw drops of blood stain the altar linen. He was traveling toward Rome. The account names Peter of Prague but presents the details as tradition; the chapel now houses the corporal.
02
From Bolsena to Orvieto
The cathedral relates that Pope Urban IV had the linen brought to Orvieto and established the feast of Corpus Christi. Orvieto still honors the corporal in an annual procession. This story belongs to the city and its liturgical memory, not merely to an image of the relic.
03
A date handled carefully
The cathedral places the event in 1263 and associates the feast with the papal bull of 1264. Carlo Acutis’s exhibition catalogue lists Bolsena under 1264. We follow the cathedral’s chronology here and show the disagreement rather than quietly picking one date.
