Thus, a Christian symbolic theme was applied quite naturally to a form borrowed from civil semi-public precedents. The first great Imperially sponsored Christian basilica is that of St John Lateran, which was given to the Bishop of Rome by Constantine right before or around the Edict of Milan in 313 and was consecrated in the year 324. In the later 4th century, other Christian basilicas were built in Rome: Santa Sabina, and St Paul's Outside the Walls (4th century), and later St Clement (6th century).
