Icons are special religious pictures used in many Christian churches, often showing Jesus, Mary, saints, or angels. People use them to remember Bible stories, to pray, or to feel close to holy people. They can be paintings on wood or other forms like mosaics, frescoes, embroidered cloths, carved stone, or metalwork, and they are made to teach and inspire with careful meaning.
Oldest surviving Christian pictures date from about the 200s AD, and a popular story says Luke the Evangelist painted the first pictures of Jesus and Mary, though historians think that legend grew later. Early Christians did not use many pictures until around 200 AD, and as Christians became settled and wealthier, more images appeared.
In the fourth century, Eusebius told stories of portraits of Jesus and the apostles in churches, and he worried that making pictures of Christ's human form might lead people to treat him like a pagan god, so he urged caution.
In the 700s and 800s, a big fight over pictures of Jesus and the saints began, called Iconoclasm. Some emperors banned or removed images because they thought they should not be worshipped, while others believed images helped people pray and learn about faith. Councils debated and rulers changed their minds, and eventually leaders restored the right to honor icons.
Acheiropoieta are icons believed to have appeared miraculously or been copied in a miracle. During the icon fights, leaders sometimes banned images, but other rulers and councils defended these miracle-linked icons, and when the right to honor icons was restored, these special images helped people trust that icons could be part of prayer.
Icons are full of signs that tell a story quickly. Artists used two common faces a long time ago—one with short, frizzy hair and another with a beard and middle-parted hair—to help viewers recognize who is pictured. Colors carry messages, with gold for heaven, red for divine life, blue for human life, and white for the bright, holy light of resurrection; halos show holiness, and tiny writing often names the people in the picture.
