Is Lycurgus Chalice 4th Century AD Really The Romans' Technological Wonder?

MessageToEagle.com – Were the ancient Romans familiar with nanotechnology and with the special properties of materials at the nano-scale?

If the Greek or Roman masters invented this nanotechnology, why are there no other examples of their skills?

If not, where did this knowledge and technological skills come from?

Some believe that Lycurgus chalice (4th century AD), we described earlier is far older than the ancient Greece or Rome.

The amazing artifact depicting King Lycurgus of Trace appears green in reflected light and red if light is directed through it.

Its extraordinary feature has long been debated by researchers but is now explained by ‘the presence of golden and silver nanoparticles that alter the color of the glass depending on the position of the observer in relation to the light…’ Koen Beumer, a PhD candidate at the department of Technology and Society Studies of Maastricht University, explains.
