The Cathedral of Orvieto is a large 14th century Roman Catholic cathedral situated in the town of Orvieto in Umbria, central Italy. The building was constructed under the orders of Pope Urban IV to commemorate and provide a suitable home for the Corporal of Bolsena, a miracle which is said to have occurred in 1263 in the nearby town of Bolsena, when a traveling priest who had doubts about the truth of transubstantiation found that his Host was bleeding so much that it stained the altar cloth. The cloth is now stored in the Chapel of the Corporal inside the cathedral. The Gothic façade of the Orvieto Cathedral is one of the great masterpieces of the Late Middle Ages. The three-gable design is attributed to Maitani, who had clearly undergone some influence by the design scheme for the façade in Tuscan Gothic style of the Siena Cathedral by Giovanni Pisano (1287–1297) and the plan for façade of the Florence Cathedral by Arnolfo di Cambio (1294–1302). The most exciting and eye-catching part is its golden frontage, which is decorated by large bas-reliefs and statues with the symbols (Angel, Ox, Lion, Eagle) of the Evangelists created by Maitani and collaborators (between 1325 and 1330) standing on the cornice above the sculptured panels on the piers. In 1352 Matteo di Ugolino da Bologna added the bronze Lamb of God above the central gable and the bronze statue of Saint Michael on top of the gable of the left entrance. The bas-reliefs on the piers depict biblical stories from the Old and New Testament. They are considered among the most famous of all 14th century sculpture.
