Catacomba di Commodilla

The name probably comes from the Roman matron who gave the land. The catacomb holds Felix and Adauctus, martyred under Diocletian in the early 4th century, in an underground basilica arranged under Damasus and Siricius and better defined under John I. Its paintings include the Madonna di Turtura, showing the Virgin enthroned between the two martyrs with the elderly woman who was buried there, a St Luke, a Traditio clavium, and the cubiculum of Leo, an official of the Annona. it.wikipedia records three levels, the middle one cut in an old pozzolana quarry, burials ending after the 4th century, devotional use in the 5th and 6th, coins of Gregory IV found on the site, and Leo IV's gift of the martyrs' relics to the wife of the Emperor Lothair. Antonio Bosio rediscovered the catacomb in 1595 and Giovanni Battista de Rossi identified it as Commodilla in the 19th century. Some burials are of the a pozzo type, shafts with up to twenty stacked loculi.
