The rarest reported type of Eucharistic miracle is where the Eucharist becomes human flesh as in the miracle of Lanciano which some believe occurred at Lanciano, Italy in the 8th century. In fact, Lanciano is only one of the reported cases of Eucharistic miracles where the host has been transformed into human flesh. However, a Eucharistic miracle more commonly reported is that of the Bleeding Host, where blood starts to trickle from a consecrated host, the bread consecrated during Mass. Other types of purported miracles include consecrated hosts being preserved for hundreds of years, such as the event of the Miraculous Hosts of Siena. Other miracles include a consecrated host passing through a fire unscathed, stolen consecrated hosts vanishing and turning up in churches, and levitating consecrated hosts.
