Today, 60 days after Easter, we celebrate the transubstantiation of the body and blood of Christ. This tradition dates back to Orvieto in Rome in the XIII century, where during mass the priest knocked the Eucharist chalice over and the few drops of wine that spilled turned into blood. Christians believe that this is proof that the Ostia and wine taken during communion are, in fact, the body and blood of Christ. In Krakow after mass, a procession will be held through Grodzka street to the main square where 4 stops will be made under temporary altars symbolizing the four evangelists. Those that take part in the procession ofter are dressed in folk dress and attire.
An interesting place to witness these events is the Corpus Christi church in Kazimierz. Legend has it, the name comes from the story of two thieves that broke into All Saints Church, which no longer stands today, and stole the monstration thinking it was of gold. After realizing it was only gold plated they threw it into the bogged area of Kazimierz. years later blue beams of light emerged from the mud in Kazimierz. The bishop was called over to see the miracle and he ordered the area to be excavated after which the stolen monstration was found. And so a church of an unusual name was built in that very spot.
