Roman art
Glass

Luxury arts included fancy Roman glass in a great range of techniques, many smaller types of which were probably affordable to a good proportion of the Roman public. This was certainly not the case for the most extravagant types of glass, such as the cage cups or diatreta, of which the Lycurgus Cup in the British Museum is a near-unique figurative example in glass that changes colour when seen with light passing through it. The Augustan Portland Vase is the masterpiece of Roman cameo glass, and imitated the style of the large engraved gems (Blacas Cameo, Gemma Augustea, Great Cameo of France) and other hardstone carvings that were also most popular around this time.
