There is an old legend among American Indians: in ancient times, there were 13 crystal skulls that could talk and sing. These crystal skulls contain information about the origin and death of human beings, which can help us solve the mystery of life in the universe. Legend also believes that one day people will find all the crystal skulls, gather them together, integrate the great wisdom of human beings and play their due role.

■ Mystery of Crystal Skull

Scientists compared the crystal skull with the real human skull and found that all the parameters were similar to the real human skull except that the eye characteristics slightly deviated from the normal range of human beings. As we know, modern optics came into being in the17th century, and it was after the rise of anatomy in the18th century that humans accurately understood their own bone structure. This crystal skull is carved on the basis of fully understanding the human skeleton structure and optical principle. How did the Mayans master these profound anatomical and optical knowledge more than 1000 years ago?

It is said that the crystal skull has hypnotic function. If you stare at the crystal skull closely, people will feel sleepy in a short time. It is said that this skull was used by horses to hypnotize patients during surgery.

In addition, crystal is one of the hardest materials in the world, so it can't be processed with tools made of copper, iron and stone. /kloc-what tools did the Mayans use more than 0/000 years ago? In addition, although this pure and transparent crystal has high hardness, its texture is brittle and fragile. Scientists infer that if it were to be made thousands of years ago, it would be possible to grind it slowly from a large crystal stone with very fine sand and water. The producer must grind it for 300 years 24 hours a day to complete such a masterpiece.
