I heard that the Mayans made a man's brain out of crystals. Is it true?/You don't say.

Although people have heard about the incomprehensible achievements of Mayan culture, the crystal skull found in the Mayan temple in Honduras in Central America in 1927 is still shocking. This skull is carved from crystal, with a height of 12.7 cm and a weight of 5.2 kg. It is the size of a real person's head, and it is carved according to a woman's head. According to ancient legends, this crystal skull has magical power and is an important tool for praying for divination in Mayan temples. It has a history of 1000 years. After studying the surface and internal structure of the skull, experts are convinced that it has a very long history and is indeed a cultural relic left over from the Mayan era.

But what puzzles the researchers is that this crystal head is carved very realistically. Not only the appearance, but also the internal structure is completely consistent with the skeleton structure of human skull. Moreover, the technology level is extremely high, and the prism hidden in the base and eye socket cooperates with the hand-polished lens to find dazzling light. As we know, modern optics came into being in the 17th century, and it was after the rise of anatomy in the 18th century that human beings 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?

Also, crystal is a timely crystal with high hardness, second only to diamond (diamond) and corundum, and cannot be processed with tools made of copper, iron or stone. Even modern people can only use modern tools such as diamonds to carve this crystal product. /kloc-The Mayans more than 0/000 years ago didn't know how to make iron. What kind of tools do they use to process this crystal skull? Have they mastered some technologies that we don't know yet?

Judging from this strange crystal skull, perhaps the Mayans mastered science and technology, which is much better than we thought. But how did they get these technologies? This is a mystery.
