The Lycurgus Cup is a 4th-century Roman glass cage cup 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.

What was the Lycurgus cup used for?

Lycurgus Cup, probably taken out only for special occasions, depicts King Lycurgus ensnared in a tangle of grapevines, presumably for evil acts committed against Dionysus, the Greek god of wine.

Who created the Lycurgus Cup?

Nanotechnology: The Science of the Invisible

Nanomaterials have been in use since ancient times, since the 4th century AD. The Lycurgus cup represents a short-lived technology developed by Roman glass workers.

What does the imagery on the Lycurgus cup represent?

It represents a type referred to as 'cage cups' (diatreta) and belongs to a rare group of dichroic glass. It depicts the punishment of king Lycurgus for his hubris against Dionysus. The focus of the paper is on the iconography of the decoration and its sym- bolism.

Did the Romans use plastic?

Ancient Rome had a culture that praised the beauty of the naked human form in both art and poetry.

How was dichroic glass discovered?

Meaning “two-colored” in Greek, dichroic glass was originally created by adding trace amounts of gold and silver to a large volume of glass melt. The resulting medium partially reflects the light passing through it, causing an observer to see different colors depending on the direction of the light source.

How a nanotechnology was discovered and developed?

Modern nanotechnology truly began in 1981, when the scanning tunneling microscope allowed scientists and engineers to see and manipulate individual atoms. IBM scientists Gerd Binnig and Heinrich Rohrer won the 1986 Nobel Prize in Physics for inventing the scanning tunneling microscope.

Can you drink colloidal gold?

Colloidal Gold for Skin

Whether you are ingesting Colloidal Gold or applying it topically, it helps with cellular activation and rejuvenation. The most optimal use of Gold is to both take it orally and use it topically; you are then feeding the cells gold from the inside and out.

Why gold nanoparticles are red?

For small (~30 nm) monodisperse gold nanoparticles, the surface plasmon resonance phenomenon causes an absorption of light in the blue-green portion of the spectrum (~450 nm) while red light (~700 nm) is reflected, yielding a rich red color.

What happens to gold nanoparticles in cells?

Once ingested or absorbed through the skin, gold nanoparticles mostly end up in the liver and spleen. There, they are internalized by macrophages and sequestered inside lysosomes – the “waste recycling centre” of cells.
