This Eucharistic miracle took place in Ferrara, in the Basilica of Saint Mary in Vado, on Easter Sunday, March 28, 1171. While celebrating Easter Mass, Father Pietro da Verona, the prior of the basilica, reached the moment of breaking the consecrated Host when he saw blood gush from it and stain the ceiling vault above the altar with droplets. In 1595 the vault was enclosed within a small shrine and is still visible today in the monumental Basilica of Santa Maria in Vado.
