The lycurgus Cup is on display at the British Museum in London. It's a goblet made by the ancient Romans 0/600 years ago. The lycurgus Cup is made of two-color glass. When the light shines from the front, the cup appears green, and when the light shines from the back, the cup appears red.

Scientists observed the glass fragments of the goblet under the microscope and found that gold and silver metal particles were dissolved in the glass, with a diameter of about 50 nanometers, which is one thousandth of the diameter of salt particles. This shows that the process similar to modern nanotechnology is used in its manufacturing process, which can decompose substances to atomic and molecular levels.

This goblet has unique optical characteristics. When the metal particles in the glass are irradiated by light, the charge vibration of the metal particles can change the color of the glass, and the color change depends on which angle the observer looks at it, which proves that the ancient Romans may be pioneers of nanotechnology.

In the Middle Ages, many important books were written with scrolls. These books can be kept for a long time, but sometimes they are destroyed for some reasons, such as being burned, bitten by insects, punctured and so on. Once broken, people will sew up the broken place with colored silk thread, which is both beautiful and can prevent the broken place from expanding further.

3. Roman multifunctional knife

The modern Swiss army knife was designed by eisner, a Swiss in 1897, and was specially designed for Swiss soldiers to use on the battlefield. The Swiss army knife has now become the standard equipment for soldiers in many countries, but between 20 1 year and 300 years, the Romans actually made the prototype of the Swiss army knife.

In the collection of Fitzwilliam Museum in Cambridge, there is a multifunctional knife used by Romans 1800 years ago. This knife is15cm long and 8cm wide. This folding knife is made of silver. Besides knives, spoons, forks, toothpicks and other basic tools, there are also a small spatula with jam and a single-tooth silver fork with snail meat. Archaeologists judged that this knife was beautifully made and should belong to Rome in those days.

2. Ancient Egyptian wooden toes

In 2000, archaeologists excavated a mummy from an ancient tomb in Egypt. This mummy wears a wooden ornament on her feet, which is the oldest artificial organ in human history, Grevel's big toe.

The history of this wooden toe can be traced back to BC 1069. The owner of this wooden toe is a woman in her fifties and sixties, the daughter of a priest in ancient Egypt. She may have lost her toe because of complications of diabetes.

This artificial toe made of wood and leather is made of four materials, and the cost should be high. Indeed, the wearer has a high status.

1, mask with glasses

Henry VIII was born on June 28th, 149 1. He is the second monarch of Tudor dynasty, and is the past of England and Ireland. But Henry VIII was actually nearsighted. He drank dozens of cups. This horned helmet is Henry VIII's special helmet.

Brass glasses frames are also worn on the eyes, which is a helmet designed according to the skull structure. The whole helmet adopts relief technology, and the concave and convex surfaces are perfectly combined. What's even more amazing is that the designer even showed details such as eyebrows, beards, people, lips and laws.
