Byzantine art - The art of the Eastern Roman Empire, the Christian empire whose capital was Constantinople (now known as Istanbul), which endured from c. 330 CE following the Roman Empire in the east, until it was conquered by the Turks c. 1450.
The term, however, refers more to a style associated with Byzantium than to its area. Byzantine paintings and mosaics are characterized by a rich use of color and figures which seem flat and stiff. The figures also tend to appear to be floating, and to have large eyes. Backgrounds tend to be solidly golden or toned. Intended as religious lessons, they were presented clearly and simply in order to be easily learned. Early Byzantine art is often called "Early Christian art."
