wildcat2030: Romans Used Nanotechnology to Turn Lycurgus Cup From Green to Red 1,600 Years Ago - Cambridge University researchers have succeeded in mimicking nanotechnology used by ancient Romans to make a 4th century AD glass cage chalice change colour in different lights. Using the same process, they have made a breakthrough that could greatly increase the storage capabilities of today’s optical devices. The Lycurgus Cup, on show at the British Museum, is 1,600 years old and highly…
The Lycurgus Cup is a Roman glass cage cup now in the British Museum, made of a dichroic glass, which shows a different colour depending on whether or not light is passing through it; red when lit from behind and green when lit from in front. The cup is a very rare example of a complete Roman cage-cup, or diatretum, where the glass has been painstakingly cut and ground back to leave only a decorative "cage" at the original surface-level. it shows the mythical King Lycurgus.

Lycurgus cup, one of the finest examples of Roman glassware made in the 4th century AD, British Museum, London The cup is an example of the diatreta or cage-cup type where the glass was cut away to create figures in high relief attached to the inner surface with small hidden bridges behind the figures. The cup is so named as it depicts the myth of Lycurgus entwined in a vine. distractio infinita
