Santa Maria in Trastevere

The basilica of Santa Maria in Trastevere is one of the oldest churches in Rome, perhaps the first in which mass was openly celebrated. This is the queen of the trasteverine churches. The inscription on the episcopal chair says that it is the first church dedicated to the Mother of God, although actually that privilege belongs to Basilica di Santa Maria Maggiore. It is certainly one of the oldest churches in the City. A Christian house-church was founded here about 220 by Pope St. Callixtus I (217-222) on the site of the Taberna meritoria, an asylum for retired soldiers. The area was given over to Christian use by the Emperor Severus when he settled a dispute between the Christians and tavern-keepers, saying, “I prefer that it should belong to those who honor God, whatever be their form of worship.” In 340 Pope Julius I (337-352) rebuilt the titulus Callixti on a larger scale, and it became the titulus Iulii, one of the original twenty-five parishes in Rome, and indeed may be the first church in which Mass was celebrated openly. It underwent two restorations in the fifth and eighth centuries, and in 1140 it was re-erected under Innocent II as a thanksgiving offering for the submission of the anti-pope, Celestine II (1124). It was rebuilt in the 12th century. The 13th-century mosaics in the apse are attributed to Pietro Cavallini. The 13th-century mosaics in the apse are attributed to Pietro Cavallini. The predecessor of the present church was probably built in the early fourth century although that church was the successor to one of the tituli, those Early Christian basilicas that were ascribed to a patron and perhaps literally inscribed with his name. Though nothing remains to establish with certainty where any of the public Christian edifices of Rome before the time of Constantine the Great were situated, the basilica on this site was known as Titulus Callisti, since a legend in the Liber Pontificalis ascribed the earliest church here to a foundation by Pope Callixtus I (died 222), whose remains, translated to the new structure, are preserved under the altar. The present nave of this Romanesque church, rebuilt by Pope Innocent II (1138 –1148) and rededicated to the Virgin Mary, preserves its original basilica plan and stands on the earlier foundations. The 22 granite columns with Ionic and Corinthian capitals that separate the nave from the aisles came from the ruins of the Baths of Caracalla, as did the lintel of the entrance door.
