The Catacombs of Marcellinus and Peter are ancient catacombs situated on the 3rd mile of the ancient Via Labicana, today Via Casilina in Rome, Italy, near the church of Santi Marcellino e Pietro ad Duas Lauros. Their name refers to the Christian martyrs Marcellinus and Peter who, according to tradition, were buried here, near the body of St. Tiburtius. In 2006, over a thousand skeletons were discovered in these catacombs; the skeletons were stacked one on top of each other and still bore the togas they were buried with. * The catacombs * Christ as Orpheus in mural painting. * * *
