Early Christian art and architecture (or Paleochristian art) is the art produced by Christians, or under Christian patronage, from the earliest period of Christianity to, depending on the definition, sometime between 260 and 525. In practice, identifiably Christian art only survives from the 2nd century onwards. After 550, Christian art is classified as Byzantine, or according to region.van der Meer, F., 27 uses "roughly from 200 to 600".

It is hard to know when distinctly Christian art began. Prior to 100, Christians may have been constrained by their position as a persecuted group from producing durable works of art. Since Christianity as a religion was not well represented in the public sphere, the lack of surviving art may reflect a lack of funds for patronage, and simply small numbers of followers. The Old Testament restrictions against the production of graven (an idol or fetish carved in wood or stone) images (see also Idolatry and Christianity) may also have constrained Christians from producing art. Christians may have made or purchased art with pagan iconography, but given it Christian meanings, as they later did. If this happened, "Christian" art would not be immediately recognizable as such.

Early Christianity used the same artistic media as the surrounding pagan culture. These media included fresco, mosaics, sculpture, and manuscript illumination. Early Christian art used not only Roman forms but also Roman styles. Late classical style included a proportional portrayal of the human body and impressionistic presentation of space. Late classical style is seen in early Christian frescos, such as those in the Catacombs of Rome, which include most examples of the earliest Christian art.

Early Christian art and architecture adapted Roman artistic motifs and gave new meanings to what had been pagan symbols. Among the motifs adopted were the peacock, Vitis viniferavines, and the "Good Shepherd". Early Christians also developed their own iconography; for example, such symbols as the fish (ikhthus) were not borrowed from pagan iconography.

Early Christian art is generally divided into two periods by scholars: before and after either the Edict of Milan of 313, bringing the so-called Triumph of the Church under Constantine, or the First Council of Nicea in 325. The earlier period being called the Pre-Constantinian or Ante-Nicene Period and the latter being the period of the First seven Ecumenical Councils. The end of the period of early Christian art, which is typically defined by art historians as being in the 5th–7th centuries, is thus a good deal later than the end of the period of early Christianity as typically defined by theologians and church historians, which is more often considered to end under Constantine, around 313–325.

Symbols

During the persecution of Christians under the Roman Empire, Christian art was necessarily and deliberately furtive and ambiguous, using imagery that was shared with pagan culture but had a special meaning for Christians. The earliest surviving Christian art comes from the late 2nd to early 4th centuries on the walls of Christian tombs in the catacombs of Rome. From literary evidence, there may well have been panel icons which, like almost all classical painting, have disappeared. Initially Jesus was represented indirectly by pictogram symbols such as the Ichthys (fish), peacock, Lamb of God, or an anchor (the Labarum or Chi-Rho was a later development). Later personified symbols were used, including Jonah, whose three days in the belly of the whale pre-figured the interval between the death and resurrection of Jesus, Daniel in the lion's den, or Orpheus' charming the animals. The image of "The Good Shepherd", a beardless youth in pastoral scenes collecting sheep, was the most common of these images, and was probably not understood as a portrait of the historical Jesus. These images bear some resemblance to depictions of kouros figures in Greco-Roman art. The "almost total absence from Christian monuments of the period of persecutions of the plain, unadorned cross" except in the disguised form of the anchor,Marucchi, Orazio. "Archæology of the Cross and Crucifix." The Catholic Encyclopedia. Vol. 4. New York: Robert Appleton Company, 1908. 7 Sept. 2018 online is notable. The Cross, symbolizing Jesus' crucifixion on a cross, was not represented explicitly for several centuries, possibly because crucifixion was a punishment meted out to common criminals, but also because literary sources noted that it was a symbol recognised as specifically Christian, as the sign of the cross was made by Christians from very early on.

The popular conception that the Christian catacombs were "secret" or had to hide their affiliation is probably wrong; catacombs were large-scale commercial enterprises, usually sited just off major roads to the city, whose existence was well known. The inexplicit symbolic nature of many early Christian visual motifs may have had a function of discretion in other contexts, but on tombs, they probably reflect a lack of any other repertoire of Christian iconography.

The dove is a symbol of peace and purity. It can be found with a halo or celestial light. In one of the earliest known Trinitarian images, "the Throne of God as a Trinitarian image" (a marble relief carved in the collection of the Prussian Cultural Heritage Foundation), the dove represents the Spirit. It is flying above an empty throne representing God, in the throne are a chlamys (cloak) and diadem representing the Son. The Chi-Rho monogram, XP, apparently first used by Constantine I, consists of the first two characters of the name 'Christos' in Greek.

Christian art before 313

A general assumption that early Christianity was generally aniconic, opposed to religious imagery in both theory and practice until about 200, has been challenged by Paul Corby Finney's analysis of early Christian writing and material remains (1994). This distinguishes three different sources of attitudes affecting early Christians on the issue: "first that humans could have a direct vision of God; second that they could not; and, third, that although humans could see God they were best advised not to look, and were strictly forbidden to represent what they had seen". These derived respectively from Greek and Near Eastern pagan religions, from Ancient Greek philosophy, and from the Jewish tradition and the Old Testament. Of the three, Finney concludes that "overall, Israel's aversion to sacred images influenced early Christianity considerably less than the Greek philosophical tradition of invisible deity apophatically defined", so placing less emphasis on the Jewish background of most of the first Christians than most traditional accounts.Finney, viii–xii, viii and xi quoted Finney suggests that "the reasons for the non-appearance of Christian art before 200 have nothing to do with principled aversion to art, with other-worldliness, or with anti-materialism. The truth is simple and mundane: Christians lacked land and capital. Art requires both. As soon as they began to acquire land and capital, Christians began to experiment with their own distinctive forms of art".Finney, 108

In the Dura-Europos church, of about 230–256, which is in the best condition of the surviving very early churches, there are frescos of biblical scenes including a figure of Jesus, as well as Christ as the Good Shepherd. The building was a normal house apparently converted to use as a church.Graydon F. Snyder, Ante pacem: archaeological evidence of church life before Constantine, p. 134, Mercer University Press, 2003, google books The earliest Christian paintings in the Catacombs of Rome are from a few decades before, and these represent the largest body of examples of Christian art from the pre-Constantinian period, with hundreds of examples decorating tombs or family tomb-chambers. Many are simple symbols, but there are numerous figure paintings either showing orants or female praying figures, usually representing the deceased person, or figures or shorthand scenes from the bible and Christian history.

The style of the catacomb paintings, and the entirety of many decorative elements, are effectively identical to those of the catacombs of other religious groups, whether conventional pagans following Ancient Roman religion, or Jews or followers of the Roman mystery religions. The quality of the painting is low compared to the large houses of the rich, which provide the other main corpus of painting surviving from the period, but the shorthand depiction of figures can have an expressive charm. A similar situation applies at Dura-Europos, where the decoration of the church is comparable in style and quality to that of the (larger and more lavishly painted) Dura-Europos synagogue and the Temple of Bel. At least in such smaller places, it seems that the available artists were used by all religious groups. It may also have been the case that the painted chambers in the catacombs were decorated in similar style to the best rooms of the homes of the better-off families buried in them, with Christian scenes and symbols replacing those from mythology, literature, paganism and eroticism, although we lack the evidence to confirm this.Balch, 183, 193 We do have the same scenes on small pieces in media such as pottery or glass, though less often from this pre-Constantinian period.

There was a preference for what are sometimes called "abbreviated" representations, small groups of say one to four figures forming a single motif which could be easily recognised as representing a particular incident. These vignettes fitted the Roman style of room decoration, set in compartments in a scheme with a geometrical structure (see gallery below). Biblical scenes of figures rescued from mortal danger were very popular; these represented both the Resurrection of Jesus, through typology, and the salvation of the soul of the deceased. Jonah and the whale,Balch, 41 and chapter 6 the Sacrifice of Isaac, Noah praying in the Ark (represented as an orant in a large box, perhaps with a dove carrying a branch), Moses striking the rock, Daniel in the lion's den and the Three Youths in the Fiery Furnace () were all favourites, that could be easily depicted.

Early Christian sarcophagi were a much more expensive option, made of marble and often heavily decorated with scenes in very high relief, worked with drills. Free-standing statues that are unmistakably Christian are very rare, and never very large, as more common subjects such as the Good Shepherd were symbols appealing to several religious and philosophical groups, including Christians, and without context no affiliation can be given to them. Typically sculptures, where they appear, are of rather high quality. One exceptional group that seems clearly Christian is known as the Cleveland Statuettes of Jonah and the Whale, and consists of a group of small statuettes of about 270, including two busts of a young and fashionably dressed couple, from an unknown find-spot, possibly in modern Turkey. The other figures tell the story of Jonah in four pieces, with a Good Shepherd; how they were displayed remains mysterious.

The depiction of Jesus was well-developed by the end of the pre-Constantinian period. He was typically shown in narrative scenes, with a preference for New Testament miracles, and few of scenes from his Passion. A variety of different types of appearance were used, including the thin long-faced figure with long centrally-parted hair that was later to become the norm. But in the earliest images as many show a stocky and short-haired beardless figure in a short tunic, who can only be identified by his context. In many images of miracles Jesus carries a stick or wand, which he points at the subject of the miracle rather like a modern stage magician (though the wand is a good deal larger).
