Once thought to have indicated a "decline" in artistic skill, early Christian art is now understood to represent a major shift in the way that artists and patrons visualized their beliefs and their world.
Two important moments played a critical role in the development of early Christianity:
The decision of the Apostle Paul to spread Christianity beyond the Jewish communities of Palestine into the Greco-Roman world.
When the Emperor Constantine accepted Christianity and became its patron at the beginning of the fourth century
The creation and nature of Christian art were directly impacted by these moments.
The spread of Christianity
As implicit in the names of his Epistles, Paul spread Christianity to the Greek and Roman cities of the ancient Mediterranean world. In cities like Ephesus, Corinth, Thessalonica, and Rome, Paul encountered the religious and cultural experience of the Greco Roman world. This encounter played a major role in the formation of Christianity.
Christianity as a mystery cult
Christianity in its first three centuries was one of a large number of mystery religions that flourished in the Roman world. Religion in the Roman world was divided between the public, inclusive cults of civic religions and the secretive, exclusive mystery cults. The emphasis in the civic cults was on customary practices, especially sacrifices. Since the early history of the polis or city state in Greek culture, the public cults played an important role in defining civic identity.
As it expanded and assimilated more people, Rome continued to use the public religious experience to define the identity of its citizens. The polytheism of the Romans allowed the assimilation of the gods of the people it had conquered.
Thus, when the Emperor Hadrian created the Pantheon in the early second century, the building’s dedication to all the gods signified the Roman ambition of bringing cosmos or order to the gods, just as new and foreign societies were brought into political order through the spread of Roman imperial authority. The order of Roman authority on earth is a reflection of the divine cosmos.
For most adherents of mystery cults, there was no contradiction in participating in both the public cults and a mystery cult. The different religious experiences appealed to different aspects of life. In contrast to the civic identity which was at the focus of the public cults, the mystery religions appealed to the participant’s concerns for personal salvation. The mystery cults focused on a central mystery that would only be known by those who had become initiated into the teachings of the cult.
Monotheism
These are characteristics Christianity shares with numerous other mystery cults. In early Christianity emphasis was placed on baptism, which marked the initiation of the convert into the mysteries of the faith. The Christian emphasis on the belief in salvation and an afterlife is consistent with the other mystery cults. The monotheism of Christianity, though, was a crucial difference from the other cults. The refusal of the early Christians to participate in the civic cults due to their monotheistic beliefs lead to their persecution. Christians were seen as anti-social.
The beginnings of an identifiable Christian art can be traced to the end of the second century and the beginning of the third century. Considering the Old Testament prohibitions against graven images, it is important to consider why Christian art developed in the first place. The use of images will be a continuing issue in the history of Christianity. The best explanation for the emergence of Christian art in the early church is due to the important role images played in Greco-Roman culture.
As Christianity gained converts, these new Christians had been brought up on the value of images in their previous cultural experience and they wanted to continue this in their Christian experience. For example, there was a change in burial practices in the Roman world away from cremation to inhumation. Outside the city walls of Rome, adjacent to major roads, catacombs were dug into the ground to bury the dead. Families would have chambers or cubicula dug to bury their members. Wealthy Romans would also have sarcophagi or marble tombs carved for their burial. The Christian converts wanted the same things. Christian catacombs were dug frequently adjacent to non-Christian ones, and sarcophagi with Christian imagery were apparently popular with the richer Christians.
Junius Bassus, a Roman praefectus urbi or high ranking government administrator, died in 359 C.E. Scholars believe that he converted to Christianity shortly before his death accounting for the inclusion of Christ and scenes from the Bible. (Photograph above shows a plaster cast of the original.)
Themes of death and resurrection
A striking aspect of the Christian art of the third century is the absence of the imagery that will dominate later Christian art. We do not find in this early period images of the Nativity, Crucifixion, or Resurrection of Christ, for example. This absence of direct images of the life of Christ is best explained by the status of Christianity as a mystery religion. The story of the Crucifixion and Resurrection would be part of the secrets of the cult.
While not directly representing these central Christian images, the theme of death and resurrection was represented through a series of images, many of which were derived from the Old Testament that echoed the themes. For example, the story of Jonah—being swallowed by a great fish and then after spending three days and three nights in the belly of the beast is vomited out on dry ground—was seen by early Christians as an anticipation or prefiguration of the story of Christ’s own death and resurrection. Images of Jonah, along with those of Daniel in the Lion’s Den, the Three Hebrews in the Firey Furnace, Moses Striking the Rock, among others, are widely popular in the Christian art of the third century, both in paintings and on sarcophagi.
All of these can be seen to allegorically allude to the principal narratives of the life of Christ. The common subject of salvation echoes the major emphasis in the mystery religions on personal salvation. The appearance of these subjects frequently adjacent to each other in the catacombs and sarcophagi can be read as a visual litany: save me Lord as you have saved Jonah from the belly of the great fish, save me Lord as you have saved the Hebrews in the desert, save me Lord as you have saved Daniel in the Lion’s den, etc.
One can imagine that early Christians—who were rallying around the nascent religious authority of the Church against the regular threats of persecution by imperial authority—would find great meaning in the story of Moses of striking the rock to provide water for the Israelites fleeing the authority of the Pharaoh on their exodus to the Promised Land.
Christianity’s canonical texts and the New Testament
One of the major differences between Christianity and the public cults was the central role faith plays in Christianity and the importance of orthodox beliefs. The history of the early Church is marked by the struggle to establish a canonical set of texts and the establishment of orthodox doctrine.
Questions about the nature of the Trinity and Christ would continue to challenge religious authority. Within the civic cults there were no central texts and there were no orthodox doctrinal positions. The emphasis was on maintaining customary traditions. One accepted the existence of the gods, but there was no emphasis on belief in the gods.
The Christian emphasis on orthodox doctrine has its closest parallels in the Greek and Roman world to the role of philosophy. Schools of philosophy centered around the teachings or doctrines of a particular teacher. The schools of philosophy proposed specific conceptions of reality. Ancient philosophy was influential in the formation of Christian theology. For example, the opening of the Gospel of John: “In the beginning was the word and the word was with God…,” is unmistakably based on the idea of the “logos” going back to the philosophy of Heraclitus (ca. 535 – 475 BCE). Christian apologists like Justin Martyr writing in the second century understood Christ as the Logos or the Word of God who served as an intermediary between God and the World.
Early representations of Christ and the apostles
An early representation of Christ found in the Catacomb of Domitilla shows the figure of Christ flanked by a group of his disciples or students. Those experienced with later Christian imagery might mistake this for an image of the Last Supper, but instead this image does not tell any story. It conveys rather the idea that Christ is the true teacher.
Christ draped in classical garb holds a scroll in his left hand while his right hand is outstretched in the so-called ad locutio gesture, or the gesture of the orator. The dress, scroll, and gesture all establish the authority of Christ, who is placed in the center of his disciples. Christ is thus treated like the philosopher surrounded by his students or disciples.
By the beginning of the fourth century Christianity was a growing mystery religion in the cities of the Roman world. It was attracting converts from different social levels. Christian theology and art was enriched through the cultural interaction with the Greco-Roman world. But Christianity would be radically transformed through the actions of a single man.
Rome becomes Christian and Constantine builds churches
In 312, the Emperor Constantine defeated his principal rival Maxentius at the Battle of the Milvian Bridge. Accounts of the battle describe how Constantine saw a sign in the heavens portending his victory. Eusebius, Constantine’s principal biographer, describes the sign as the Chi Rho, the first two letters in the Greek spelling of the name Christos.
After that victory Constantine became the principal patron of Christianity. In 313 he issued the Edict of Milan which granted religious toleration. Although Christianity would not become the official religion of Rome until the end of the fourth century, Constantine’s imperial sanction of Christianity transformed its status and nature. Neither imperial Rome or Christianity would be the same after this moment. Rome would become Christian, and Christianity would take on the aura of imperial Rome.
The transformation of Christianity is dramatically evident in a comparison between the architecture of the pre-Constantinian church and that of the Constantinian and post-Constantinian church. During the pre-Constantinian period, there was not much that distinguished the Christian churches from typical domestic architecture. A striking example of this is presented by a Christian community house, from the Syrian town of Dura-Europos. Here a typical home has been adapted to the needs of the congregation. A wall was taken down to combine two rooms: this was undoubtedly the room for services. It is significant that the most elaborate aspect of the house is the room designed as a baptistry. This reflects the importance of the sacrament of Baptism to initiate new members into the mysteries of the faith. Otherwise this building would not stand out from the other houses. This domestic architecture obviously would not meet the needs of Constantine’s architects.
Emperors for centuries had been responsible for the construction of temples throughout the Roman Empire. We have already observed the role of the public cults in defining one’s civic identity, and Emperors understood the construction of temples as testament to their pietas, or respect for the customary religious practices and traditions. So it was natural for Constantine to want to construct edifices in honor of Christianity. He built churches in Rome including the Church of St. Peter, he built churches in the Holy Land, most notably the Church of the Nativity in Bethlehem and the Church of the Holy Sepulcher in Jerusalem, and he built churches in his newly-constructed capital of Constantinople.
The basilica
In creating these churches, Constantine and his architects confronted a major challenge: what should be the physical form of the church? Clearly the traditional form of the Roman temple would be inappropriate both from associations with pagan cults but also from the difference in function. Temples served as treasuries and dwellings for the cult; sacrifices occurred on outdoor altars with the temple as a backdrop. This meant that Roman temple architecture was largely an architecture of the exterior. Since Christianity was a mystery religion that demanded initiation to participate in religious practices, Christian architecture put greater emphasis on the interior. The Christian churches needed large interior spaces to house the growing congregations and to mark the clear separation of the faithful from the unfaithful. At the same time, the new Christian churches needed to be visually meaningful. The buildings needed to convey the new authority of Christianity. These factors were instrumental in the formulation during the Constantinian period of an architectural form that would become the core of Christian architecture to our own time: the Christian Basilica.
The basilica was not a new architectural form. The Romans had been building basilicas in their cities and as part of palace complexes for centuries. A particularly lavish one was the so-called Basilica Ulpia constructed as part of the Forum of the Emperor Trajan in the early second century. Basilicas had diverse functions but essentially they served as formal public meeting places. One of the major functions of the basilicas was as a site for law courts. These were housed in an architectural form known as the apse. In the Basilica Ulpia, these semi-circular forms project from either end of the building, but in some cases, the apses would project off of the length of the building. The magistrate who served as the representative of the authority of the Emperor would sit in a formal throne in the apse and issue his judgments. This function gave an aura of political authority to the basilicas.
The basilica at Trier (Aula Palatina)
Basilicas also served as audience halls as a part of imperial palaces. A well-preserved example is found in the northern German town of Trier. Constantine built a basilica as part of a palace complex in Trier which served as his northern capital. Although a fairly simple architectural form and now stripped of its original interior decoration, the basilica must have been an imposing stage for the emperor. Imagine the emperor dressed in imperial regalia marching up the central axis as he makes his dramatic adventus or entrance along with other members of his court. This space would have humbled an emissary who approached the enthroned emperor seated in the apse.
