Byzantine art originated and evolved from the Christianized Greek culture of the Eastern Roman Empire; content from both Christianity and classical Greek mythology were artistically expressed through Hellenistic modes of style and iconography. The art of Byzantium never lost sight of its classical heritage; the Byzantine capital, Constantinople, was adorned with a large number of classical sculptures, although they eventually became an object of some puzzlement for its inhabitants (however, Byzantine beholders showed no signs of puzzlement towards other forms of classical media such as wall paintings). The basis of Byzantine art is a fundamental artistic attitude held by the Byzantine Greeks who, like their ancient Greek predecessors, "were never satisfied with a play of forms alone, but stimulated by an innate rationalism, endowed forms with life by associating them with a meaningful content." Although the art produced in the Byzantine Empire was marked by periodic revivals of a classical aesthetic, it was above all marked by the development of a new aesthetic defined by its salient "abstract", or anti-naturalistic character. If classical art was marked by the attempt to create representations that mimicked reality as closely as possible, Byzantine art seems to have abandoned this attempt in favor of a more symbolic approach.
