Early Christian and Byzantine Architecture
The Early Christian Basilica.
When the emperor Constantine recognized Christianity as the official state religion early in the fourth century, Christians were able to practice their faith openly. Whereas before they had met in secret in the catacombs and in other non-public places, they were now free to act as an organized and recognized cult. The first Christian meeting places were private houses and it was only when the religious ritual became more formalized that a special building was needed. It was probably to divorce themselves from the old religions that the forms of the "pagan" Greek and Roman temples were not utilized for Christian worship. The long rectangular form of the civil basilica was easily adapted for this use, although some changes had to be made. The basilica was basically a meeting house where large groups could be accommodated to conduct business and carry on other civil functions, although some changes had to be made to the form for its new religious purpose. The normal civic basilica had its entrance on one side, and this was altered to accommodate the interior orientation and direction necessary in the church. One of the best examples of an early Christian basilica was the original Church of St. Peter in Rome. It was erected by order of the emperor Constantine on the site of the Circus of Nero where the apostle Peter was martyred. Its construction was begun in 324 c.e. but it was destroyed at the end of the fifteenth century to make room for a later church. There is considerable evidence in drawings and plans to indicate its design. Its general layout included an atrium, a large open courtyard that the participants passed through to enter the body of the church. Although the main meeting hall followed the general plan of the civil basilica, the addition of the atrium recalled the form of the private houses originally used for worship. In the Church of St. Peter a large central aisle known as the nave was flanked on each side by two parallel side aisles. Only the largest churches had five aisles; it was more typical to have a large central nave with only two side aisles. The focus of the religious ritual was at the altar at the far end from the entrance, exactly like the arrangement in most Christian churches even today. While the exterior and interior walls and columns were of stone, the roof over the nave and side aisles was of wood. This was a pattern followed in most early Christian churches of the basilica type, disregarding the use of stone or brick vaulting in favor of economical and easily constructed wooden roofing. The form that had been designed as a meeting place to accommodate large crowds for the conduct of business and government affairs used throughout the Roman world had evolved into the standard for a place of Christian worship. The pattern established by the first Church of St. Peter was followed in many early churches. A typical example is the Church of Santa Sabina in Rome, begun in 425. Its arrangement follows the basilica pattern with the addition of a half dome over the apse, the semicircular niche at the end of the nave. In it, as in many early churches, the columns supporting the side walls of the nave were taken from earlier buildings. In some cases the reuse of such building elements was done without any concern for their style or order. Mosaics were used extensively for decoration on the façade, in the interior on the side walls and in the apse. These enlivened the interior with color and reflected light but they also served as informative and devotional illustrations of scripture.
The Development of the Byzantine Church.
The city known in antiquity as Byzantium was re-founded by Constantine as the "New Rome" in 333 c.e. At the breakup of the Roman Empire by the successors of Constantine in 335 it became the capital of the Eastern Roman Empire with the new name of Constantinople. The development of church architectural style in the east, while serving the same purposes as in the west, took on somewhat different form. There are a number of reasons suggested to explain the difference, including the scarcity of wood for the roofing, resulting in a return to the arches and vaulting developed by Roman architects. Although this may be part of the explanation, it is more likely that the church architecture in the east—Byzantium—was the result of a combination of local traditions of construction and the influence of Eastern (Persian) architecture. While Roman architects had been comfortable with the design of round buildings such as the Parthenon that could be roofed with a dome, Byzantine architects were faced the problem of a circular dome resting on a square or rectangular building. This problem could be solved in two ways: by the use of squinches or by pendentives. The squinch uses an octagonal arrangement formed by bridging the corners with a lintel or an arch. The pendentive uses a second dome form from which sections have been removed leaving a circular base supported by four triangular sections resting on four piers. Hagia Sophia in Istanbul, which essentially follows the layout of a basilica, is an example of the use of domes supported by pendentives. One variation of a plan popular in the east was a central arrangement in a circular or octagonal building, as can be seen in the Church of San Vitale in northwest Italy, constructed between 526 and 547. The central arrangement or circular form never became popular in the west except for baptisteries and other special purposes. The separate architectural traditions of east and west continued into modern times and are still evident in the differences between modern churches of the Greek Orthodox rite and those of the more Western tradition.
