History

The wonderful 4th century #Roman Lycurgus Cup, from the @britishmuseum. It is made of a dichroic glass & changes colour - red if lit from behind & green if lit from the front. It is the only complete Roman object found made of this type of glass. See https://t.co/GsjjpKnHZp. pic.twitter.com/qHBhAVnjoc
