A Basilian monk who doubted the real presence of Christ in the Eucharist experienced an extraordinary event during Holy Mass. After the words of consecration, the bread and wine transformed before his eyes into living flesh and blood.

The blood coagulated into five globules of different sizes. This miracle became witness for all present and would be preserved throughout the centuries.

The first known written record of this event dates from 1574, although oral tradition is much older. A detailed documentation was created in 1631.
