in 1907. The building is a national monument visited by many tourists for its works of art, such as the cycle of frescoes of the Roman school (1150) prior to Cavallini; the frescoes in the apse by the Eggi master of 1445. Art The church, which has remained as a separate body from the abbey, has a single nave that dates back to the 7th century; the apse dates back to the 12th century. It preserves valuable medieval and Renaissance frescoes from the Umbrian school depicting scenes from the Old and New Testament. Four sarcophagi preserved in the church date back to the 2nd century, which for the style and the representations suggest oriental artists: Sarcophagus with three boats (voyage to Hades). Sarcophagus of Faroaldo with Dionysus, Silenus, Pan and dancing Maenad. Sarcophagus of Cupid and Psyche Sarcophagus of the hunters. The carved slab of Bear The two slabs of the main altar, carved in bas-relief, are from the Lombard period. On the front of the altar runs an inscription in Latin, with curious mixed capital and lowercase characters: "Ilderico Dagileopa, in honor of St. Peter and for the love of St. Leo and St. Gregory, for the salvation of the soul (pro remedio animae) ". Ilderico was Duke of Spoleto between 739 and 742. The slab is also adorned with two bizarre figures, with their arms bent at 90 ° and raised upwards, with bare chest and wearing a short skirt. The figures are surrounded by stylized plant stems, which culminate in discs with inscribed crosses. One of the two figures wields a sort of stiletto, which some believe to be a chisel. This would suggest that the figure represents Ursus (Bear), the sculptor indicated as the author of the engraving by the inscription Ursus magester fecit ("The master Bear did it"). It is more difficult to understand who the other figure is: the kilt, a garment perhaps suited to the activity of a sculptor, does not suit the dignity of the duke. The raised arms have been interpreted as a ritual attitude and, in this case, the kilt would correspond to the cloth that is worn after baptism (which, in ancient times, was carried out by complete immersion). The pose would correspond to that of the contemporary bone altar of the Bishop Ludgero in Werden (hamlet of Essen) or to that of the sarcophagus of Bishop Agilbert in
