the messages contained in Quran, Vedas, Upanishads, Talmud and Avesta. Atheists reject Jesus' divinity, but have different views about him – from challenging his mental health to emphasizing his "moral superiority" (Richard Dawkins). Artistic depictions Some of the earliest depictions of Jesus at the Dura-Europos church are firmly dated to before 256. Thereafter, despite the lack of biblical references or historical records, a wide range of depictions of Jesus appeared during the last two millennia, often influenced by cultural settings, political circumstances and theological contexts. As in other Early Christian art, the earliest depictions date to the late 2nd or early 3rd century, and surviving images are found especially in the Catacombs of Rome. The depiction of Christ in pictorial form was highly controversial in the early Church. From the 5th century onward, flat painted icons became popular in the Eastern Church. The Byzantine Iconoclasm acted as a barrier to developments in the East, but by the 9th century, art was permitted again. The Protestant Reformation brought renewed resistance to imagery, but total prohibition was atypical, and Protestant objections to images have tended to reduce since the 16th century. Although large images are generally avoided, few Protestants now object to book illustrations depicting Jesus. The use of depictions of Jesus is advocated by the leaders of denominations such as Anglicans and Catholics and is a key element of the Eastern Orthodox tradition. The Transfiguration was a major theme in Eastern Christian art, and every Eastern Orthodox monk who had trained in icon painting had to prove his craft by painting an icon depicting it. Icons receive the external marks of veneration, such as kisses and prostration, and they are thought to be powerful channels of divine grace. The Renaissance brought forth a number of artists who focused on depictions of Jesus; Fra Angelico and others followed Giotto in the systematic development of uncluttered images. Before the Protestant Reformation, the crucifix was common in Western Christianity. It is a model of the cross with Jesus crucified on it. The crucifix became the central ornament of the altar in the 13th century, a use that has been nearly universal in Roman Catholic churches since then. Jesus appears as an infant in a manger (feed trough) in Christmas creches, which depict the Nativity scene. He is typically joined by Mary, Joseph, animals, shepherds, angels, and the Magi.
