Lycurgus Cup (VIDEO) Washington University in St. Louis This video is under embargo. Please login to access this video. Caption Lycurgus, King of the Edoni in Thrace, is ensnared by the nymph Ambrosia in the form of a vine. The famous Roman cup looks green when lit from outside but glows pink when lit from inside. Gold nanocages made at Washington University exploit the same physical effect that underlies the cup's color change.
