very similar to what became the traditional image of Jesus, with a longish face and long straight hair. As the Church increased in size and popularity, the need to educate illiterate converts led to the use of pictures which portrayed biblical stories, along with images of saints, angels, prophets, and the Cross (though only portrayed in a bejewelled, glorified state). After the end of persecution, and the adoption of Christianity by Constantine, large churches were built and from the start decorated with elaborate images of Jesus and saints in mosaic. Small carved reliefs were also found on sarcophagi like the Sarcophagus of Junius Bassus. However large monumental sculpture of religious subjects was not produced, and in Byzantine art and Eastern Orthodox art it is avoided to the current day. It only reappeared in Carolingian art, among peoples who had no memory of pagan religious statues. Paintings of Old Testament scenes are found in Jewish catacombs of the same period, and the heavily painted walls of Dura Europos Synagogue in Syria. Catholic and Orthodox historians affirm, on the basis of these archeological finds in the Catacombs, that the veneration of icons and relics had begun well before Constantine I. Christian use of relics also dates to the catacombs, when Christians found themselves praying in the presence of the bodies of martyrs, sometimes using their tombs as altars for sharing the Eucharist, which was, and in Catholicism, Lutheranism and Eastern Orthodoxy is, the central act of Christian worship. Many stories of the earliest martyrs end with an account of how Christians would gather up the martyr's remains, to the extent possible, in order to retain the martyr's relics. This is shown in the written record of the martyrdom of Saint Polycarp, a personal disciple of Saint John the Apostle. Significant periods of iconoclasm (deliberate destruction of icons) have occurred in the history of the Church, the first major outbreak being the Byzantine iconoclasm (730-787), motivated by a strictly literal interpretation of the second commandment and interaction with Muslims who have a very strict teachings against the creation of images. Iconoclasm was officially condemned by the Western and Eastern Churches at the Second Council of Nicaea in 787 AD (the Western Church was not represented, but approved the decrees later). This decision was based on the arguments including that the biblical commandment forbidding images of God was because no-one had seen God. But,
