An icon (from the Greek εἰκών eikṓn 'image, resemblance') is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, the Roman Catholic, and certain Eastern Catholic churches. They are not simply artworks; "an icon is a sacred image used in religious devotion".[1] The most common subjects include Christ, Mary, saints and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints.
Icons are most commonly painted on wood panels with egg tempera, but they may also be cast in metal, carved in stone, embroidered on cloth, done in mosaic or fresco work, printed on paper or metal, etc. Comparable images from Western Christianity can be classified as "icons", although "iconic" may also be used to describe a static style of devotional image. In the Greek language the term for icon painting uses the same word as for "writing", and Orthodox sources often translate it into English as icon writing.[2]
Eastern Orthodox tradition holds that the production of Christian images dates back to the very early days of Christianity, and that it has been a continuous tradition since then. Modern academic art history considers that, while images may have existed earlier, the tradition can be traced back only as far as the 3rd century, and that the images which survive from Early Christian art often differ greatly from later ones. The icons of later centuries can be linked, often closely, to images from the 5th century onwards, though very few of these survive. Widespread destruction of images occurred during the Byzantine Iconoclasm of 726–842, although this did settle permanently the question of the appropriateness of images. Since then icons have had a great continuity of style and subject; far greater than in the icons of the Western church. At the same time there has been change and development.
Pre-Christian religions had produced and used art works.[4] Statues and paintings of various gods and deities were regularly worshiped and venerated. It is unclear when Christians took up such activities. Christian tradition dating from the 8th century identifies Luke the Evangelist as the first icon painter, but this might not reflect historical facts.[5]
Aside from the legend that Pilate had made an image of Christ, the 4th-century Eusebius of Caesarea, in his Church History, provides a more substantial reference to a "first" icon of Jesus. He relates that King Abgar of Edessa (died c. 50 CE) sent a letter to Jesus at Jerusalem, asking Jesus to come and heal him of an illness. This version of the Abgar story does not mention an image, but a later account found in the Syriac Doctrine of Addai (c. 400 ?) mentions a painted image of Jesus in the story; and even later, in the 6th-century account given by Evagrius Scholasticus , the painted image transforms into an image that miraculously appeared on a towel when Christ pressed the cloth to his wet face.[6] Further legends relate that the cloth remained in Edessa until the 10th century, when it was taken by General John Kourkouas to Constantinople. It went missing in 1204 when Crusaders sacked Constantinople, but by then numerous copies had firmly established its iconic type.
