First, the customs of Mexican aborigines.
Maya crystal head carvings are exaggerated, abstract and similar in style, and are generally small. The British Museum has two small skulls identified as ancient Mexico. The small ones are carved with talc, and the big ones are carved with crystal. The height is only 1.25 inches, and both of them have holes. There are also crystal skulls in the Paris Museum, but they are about half the size of real skulls. This is because the Aztecs, the original inhabitants of Mexico, carved human skulls with stones, bones, wood and other materials, called "death heads". Moreover, there is a legend among Native Americans: "The ancestors left 13 crystal skulls. If they are put together, they will reveal the secrets of human past and future. "
Second, the Mayan secret ceremony.
The crystal skull has a history of more than 3600 years. According to some records, the Mayan high priest used it in some secret ceremonies. It is said that the high priest can use this skull to issue death orders, and death is bound to come. It is described as the embodiment of all evil. As for when and where the high priest got the skull, she never said. The high priest just said vaguely, "I have reason not to disclose how I used him." At the beginning, Anna, the daughter of an archaeologist, discovered the "Mayan crystal skull" in a pyramid while excavating Mayan ruins in Honduras, England. However, some versions of the book have been deleted from the backboard of the skull.
However, the real secret of the crystal skull was finally discovered by scientists with current technology. After testing, this crystal skull is very similar to manual processing. To sum up, the Mayans may have really used skulls, but the secret of the "crystal skull" is a lie of a century and a modern handicraft.
