Archeological discoveries in the 19th and 20th centuries unearthed a large group of Early Byzantine mosaics in the Middle East. The eastern provinces of the Eastern Roman and later the Byzantine Empires inherited a strong artistic tradition from the Late Antiquity. Christian mosaic art flourished in this area from the 4th century onwards. The tradition of making mosaics was carried on in the Umayyad era until the end of the 8th century. The most important surviving examples are the Madaba Map, the mosaics of Mount Nebo, Saint Catherine's Monastery and the Church of St Stephen in ancient Kastron Mefaa (now Umm ar-Rasas).
