The reliquaries of two Eucharistic miracles which took place in 1230 and 1595 are held in Florence’s Church of Saint Ambrose. In the 1230 miracle, a distracted priest left several drops of consecrated wine in the chalice after Mass. The next day, returning to celebrate Mass in the same church, he found in the chalice drops of living Blood coagulated and incarnated. The Blood was immediately kept in a crystal cruet. The other Eucharistic miracle took place on Good Friday in 1595, when several fragments of the Host were miraculously unharmed in a church fire.
