Orvieto was the birthplace for the feast of the Eucharist, called Corpus Domini, and one of the major feasts of the Catholic church. The Cathedral of Orvieto holds a treasure – a number of them, really, including frescos by Luca Signorelli, Gentile di Fabriano, and Fra Angelico. But its spiritual treasure is a relic from the Miracle of Bolsena, the miracle which was the final impetus in the church’s decision to institute the festival of Corpus Domini: “Body of the Lord”. This feast is a reminder to artists and non-artists alike that Art and Beauty can model the Incarnation in the world.
