The shape, style and decoration of this example are typical of lamps produced during the final centuries of the Empire and the early Byzantine period: the most active workshops were located in North African cities, but their
products were often imitated elsewhere, notably in Italy and Gaul.
This example was blown in a gold-amber glass with beautiful and varied white streaks. The slightly asymmetrical shape is characterized by a piriform body, which tapers in the upper part and terminates in a cylindrical neck and a flat lip.
