Rome’s Fascinating Basilica of San Clemente Reveals 2,000 Years of History

I descended 60 feet below Rome’s surface into a mysterious past I knew little about…

The ancient Basilica of San Clemente, named after Rome’s third pope, hardly drew my attention as I passed by on my walk from the Colosseum. I soon discovered that I had approached the basilica from the side by mistake, missing the grand entrance fronted by a small courtyard with palm trees.

I had previously read about the basilica’s three levels of fascinating history, one church on top of another. The present 12th-century basilica was erected on the site of a previous church which had been buried for centuries underneath the level of the city streets.

Inside the basilica, adorned with dazzling mosaics, I noticed the golden apse depicting Christ on the Cross surrounded by doves. I walked across the uneven tile floor as it dipped and swayed through the centuries of visiting pilgrims and worshipers. A faint smell of incense, mingled with a cool earthiness, grew stronger as I began my journey from the sacristy down a flight of stairs and into the depths of the 4th century Church of San Clemente.

The existing 4th century basilica served as the foundation for the newer church.  The builders simulated the earlier church in nearly every way including the nave, aisles, clerestory windows, arcades (arches), the simple apse, and an open wooden roof that is now hidden by a ceiling that has been ornately decorated. The only difference made was a somewhat narrower structure accompanied by piers halfway down the nave.

Today much of the ancient Roman heritage has been obscured by an eighteenth-century renovation. Part of the church was actually the upper room of a second-century Roman mansion directly below it, owned by Titus Flavius Clemens, one of the first Roman senators to convert to Christianity. His house was used for secret Christian worship until Christianity was legalized in 313 AD. under Emperor Constantine. I noticed the similar floor plan of the 12th-century basilica above. Rows of stout columns stood as support among faded frescoes on the old stone walls. Bits of mosaic flooring can still be seen. One of the better-preserved wall frescoes depicts The Legend of St. Alexis, a 3rd century Syrian who denied his wealth to live and care for the poor.

The smell of dank earthiness increased, creating a growing sense of an unfamiliar time. I descended an even older set of steps to the bottom level of the basilica. Here I found the remains of a first century building believed to have belonged to a man by the name of Clement and believed to be a relative of the Consul-Martyr Titus Flavius Clemens, St. Clement’s contemporary. It is believed that a room was set aside here for Christian worship which was likely illeagal at the time.

A second-century temple of the pagan god Mithras inside a cave-like room stood just across the ancient street. The altar depicted a carving of Mithras slaying a bull. Long low stone benches for seating ran along two sides of the room. During the first century, this Persian cult grew in popularity particularly among the Roman soldiers but was eventually eradicated by Roman Christians.

Later excavations found a 4th layer underneath that contain buildings destroyed in the fire of Nero in 64 AD. Interesting to note, after the fire, the buildings were filled in and used as foundations for further houses. The level of the valley in which San Clemente lies was actually about sixty feet lower in the first century than the present level.

I could hear the sound of rushing water close by. Following the remains of a corridor, I passed a room thought to have been used as a Mithras school. At the end, I found a small room with a gurgling spring from some unknown source viewable in the corner that ran under the floor.

As I retraced my steps, I began to pull together all that my senses had collected. Images started to form of another time long ago. Before Christianity was legal. While paganism flourished. Beginning with the reign of unstable emperors. A time when there was no middle class, only slaves, and freedmen. Dangerous times…..
