Christian art is sacred art which uses themes and imagery from Christianity. Most Christian groups use or have used art to some extent, although some have had strong objections to some forms of religious image, and there have been major periods of iconoclasm within Christianity.
Images of Jesus and narrative scenes from the Life of Christ are the most common subjects, and scenes from the Old Testament play a part in the art of most denominations. Images of the Virgin Mary and saints are much rarer in Protestant art than that of Roman Catholicism and Eastern Orthodoxy.
Christianity makes far wider use of images than related religions, in which figurative representations are forbidden, such as Islam and Judaism. However, there is also a considerable history of aniconism in Christianity from various periods.
Early Christian art survives from dates near the origins of Christianity. The oldest Christian sculptures are from sarcophagi, dating to the beginning of the 2nd century. The largest groups of Early Christian paintings come from the tombs in the Catacombs of Rome, and show the evolution of the depiction of Jesus, a process not complete until the 6th century, since when the conventional appearance of Jesus in art has remained remarkably consistent.
Until the adoption of Christianity by Constantine Christian art derived its style and much of its iconography from popular Roman art, but from this point grand Christian buildings built under imperial patronage brought a need for Christian versions of Roman elite and official art, of which mosaics in churches in Rome are the most prominent surviving examples. Christian art was caught up in, but did not originate, the shift in style from the classical tradition inherited from Ancient Greek art to a less realist and otherworldly hieratic style, the start of gothic art.
