Mosaics at the Zeugma excavation

Zeugma was located at the only crossing place between Anatolia and Mesopotamia; it is estimated that two or three thousand houses are buried there.  A series of excavations currently underway there is revealing some startling mosaics. "The mosaics, created in the 2nd century BC, are constructed of boldly colored glass and are being covered for protection until excavation is complete."
