The Lycurgus Cup
Date: 4th century AD
From: probably made in Rome
This glass cup shows a scene from a Greek story. Lycurgus, a king with a fierce temper, is being trapped by vines as a punishment for his behaviour.
The cup is special for two reasons: firstly it is the only complete example of a kind of glass called dichroic glass. Dichroic glass changes colour from green to a glowing red when light is shone through it.
The cup is also the best example we have of a 'cage-cup'. It is made from a solid block of glass that has been carefully carved away until the cup and the figures standing out on it are left.
