Conical glass vessels decorated with applied blue blobs are known from sites throughout the Empire. Some served as drinking bowls or beakers, but others were used as lamps. This vessel is certainly more appropriate for the latter use, and it would have cast attractive rays of colored light when suspended from the ceiling. Glass hanging lamps became the most popular form of lighting for churches in Byzantine times and were also adopted for use in mosques.
