Byzantine art and architecture
For more than a thousand years, until the conquest of Constantinople by the Turks in 1453, Byzantine art retained a remarkably conservative orientation; the major phases of its development emerge from a background marked by adherence to classical principles. Artistic activity was temporarily disrupted by the Iconoclastic controversy (726–843), which resulted in the wholesale destruction of figurative works of art and the restriction of permissible content to ornamental forms or to symbols like the cross. The pillaging of Constantinople by the Frankish Crusaders in 1204 was perhaps a more serious blow; but it was followed by an impressive late flowering of Byzantine art under the Paleologus dynasty.
