Most late Hellenistic glass drinking cups are made of colorless or monochrome translucent glass. This example is highly unusual in that it is made from fused canes of polychrome mosaic glass, which include bands of gold leaf between two layers of colorless glass. The cup, despite its fragmentary condition, is probably the largest surviving example of an ancient vessel made using gold-band glass. It may have been made for the luxury market in Rome.
