It was not until the late third century B.C. that mosaic glass vessels began to be produced in any quantity, and they became one of the most distinctive and attractive types of Hellenistic glassware. Many are in the form of hemispherical bowls like this example or large plates of similar shape to the colorless one (1999.315) also displayed here. Both shapes are represented in the Canosa Group, named for the site in South Italy where numerous examples of luxury Hellenistic glassware have been found in tombs.
