Santa Prisca, Rome

Santa Prisca is a titular church of Rome, on the Aventine Hill, for Cardinal-priests. It is recorded as the Titulus Priscae in the acts of the 499 synod.
It is devoted to Saint Prisca, a 1st-century martyr, whose relics are contained in the altar in the crypt. It was built in the 4th or 5th century over a temple of Mithras. Damaged in the Norman Sack of Rome, the church was restored several times. The current aspect is due to the 1660 restoration, which included a new facade by Carlo Lombardi. In the interior, the columns are the only visible remains of the ancient church. Also a baptismal font allegedly used by Saint Peter is conserved. The frescoes in the crypt, where an altar contains the relics of Saint Prisca, are by Antonio Tempesta. Anastasio Fontebuoni frescoed the walls of the nave with Saints and angels with the instruments of passion. In the sacristy hangs a painting of the Immaculate conception with angels by Giovanni Odazzi, and on the main altar a Baptism of Santa Prisca by Domenico Passignano.
The Mithraeum under Santa Prisca was first discovered in 1934, having been excavated by Augustinians who had been in charge of the monastery. Excavations by the Dutch began in 1952–59. The original building was erected in ca. 95 CE and was originally a plot of land purchased by Trajan, who at the time was not yet emperor of Rome. This had also served as Trajan's town house until his death in 117 A.D. One hundred years later, a member of the imperial family took over the building and built a Mithraeum in one part of the basement, while a Christian meeting place was established in the other section.
Upon beginning the excavations in 1952, the Dutch cleared away mounds of earth which were thought to have been a sort of trench. During this period, many artifacts were discovered by the Dutch who made a careful record. Some of these discoveries included frescoes, mosaics, remains of various vases, stucco, as well as fragments of mosaic and brick. The original Mithrauem had a central aisle, a niche, and side benches. Fine frescoes were found on the walls of the ancient Mithraeum as well as a stucco sculpture of Mithras the Bull Slayer, one of the main images of the Mithras cult. During the Dutch excavations in the 1950s, pieces of mosaic were found within the newly discovered rooms underneath Santa Prisca. Renovations in 220 yielded a larger central cult room and the addition of new ones while the frescoes were covered with new, more elaborate paintings. The frescoes often included writing underneath or around the work, which would describe what that fresco showed. This is something unique to the Mithraic temple found at Santa Prisca. These paintings were also important to the development of understanding the Mithraic cult. Along with the typical bull slaying scene so commonly depicted amongst the cult, other paintings depicted different cult rituals. For example, one painting shows a procession of figures wearing masks and different colored tunics holding what has been presumed to be a piece of liturgical equipment. These paintings have been mentioned in the long-standing debate about the admittance of women into the cult. Around 400, the Christians took over the Mithraeum, destroyed it and built Santa Prisca on top of it.
The excavations of the Mithraeum by the Dutch in the mid 20th century proved to have found leftover fragments of frescoes. The Mithraeum had been embellished with paintings, and these frescoes, in particular, contain imagery and iconography which depict particular beliefs in the Mithraic cult as well as elements of initiation. One of the frescoes on the left wall within the Mithraeum of the Roman Church includes a depiction of a cult processional towards figures Mithra and Sol, with those participating in the cult holding various objects as they make their way to their deities. Both the left and right walls in the Mithraeum of Santa Prisca have remnants of paintings which depict different scenes and include several figures; however, due to destruction, some of the images are difficult to make out. The left wall of the temple shows several walking male figures, some youthful and full of energy. They are seen in brown and yellow color tunic holding objects like pans, terracotta and glass vessels, even animals like chickens. Another figure in the painting is seen standing, wearing a red tunic and is depicted with a raven face mask and proffering an oblong dish. Other depictions within the frescoes of the Mithraeum include soldiers holding their military bags. Within the Mithraic cult, there is an initiation of seven grades, which are also referred to as the seven planetary grades of salvation. It is thought that this fresco in Santa Prisca is a depiction of the seven grades of initiation, though it is hard to be certain with only the fragmentary evidence that remains. The right wall fresco in the Mithraeum features the seven grades arranged in the exact order (followed by their symbols):
The Dutch excavations of M. J. Vermaseren and C. C. Essen in the mid 20th century also revealed there to be paintings in the temples underneath the church. The whole sanctuary was found to have been originally painted by the members of the cult. The Mithraeum's entrance had been stuccoed and painted red, also featuring a painted blue ceiling with stars. Both the temples within the Mithraeum have paintings of an initiate processional and Sol seen with pierced rays for illumination as well as painted remnants which are believed to be fruit baskets and flowers.
The findings of Vermaseren and Essen also found there to be similarities to another Mithreaum in Ostia Antica, a harbor city 19 miles (30 kilometers) from Rome. The architectural analysis suggests that the Mithraeum under the Santa Prisca Church in Rome had undergone construction and was enlarged around the year 220 A.D. Similarities between the two Mithraic temples also suggest that those in the cult who had worked on the Mithraeum in Ostia had helped in the construction and painting of the Mithraeum in Santa Prisca.
The Cardinal Priest of the Titulus S. Priscae is Justin Francis Rigali, Cardinal Archbishop Emeritus of Philadelphia (US).
