The Aztecs of the indigenous inhabitants of Mexico used the stone, bones, wood and other materials to engrave the human skull, called the "death head." Some of them are carved in crystal, exaggerated, abstract, and more consistent in style, and generally very small. For example, the British Museum houses two small skulls identified as belonging to "Ancient Mexico". The smaller one is carved with talc, the larger one is carved with crystal, and the height is only 1.25 inches. Both have perforations, which are estimated to be used as rosary or amulets. A museum in Paris also houses a crystal skull, about half the size of a human skull, which French experts believe was made by the Aztecs in the 14th or 15th centuries. But this is not a mysterious phenomenon or a crystal skull as advocated by the "new age religion" advocate. The crystal skull in their minds is about the size of a real human skull. The style is realistic and vivid. It is said to be the sacred object of the Maya and has mysterious power. They also claimed that the Native American inhabitants had a legend, and the ancestors left thirteen crystal skulls. If they were put together, they would reveal the secrets of humanity's past and the end. The most famous crystal skull was later owned by the British explorer Frederick Albert Mitchell-Hedges, known as the Michelle-Hégis Crystal Skull, Michelle. - Heggis calls it "SkullofDoom." Michelle Haggis only mentioned the skull in the autobiography "Danger MyAlly" published in 1954, and has remained silent since then. This book is not so much an autobiography as it is a fictional novel. The authenticity of many of the events recorded in it is very doubtful, and some are obviously fabricated. He claimed to have played poker with Morgan, the American steel king, drifting in the southern United States, creating a number of Shanghai fishing records, and even once the Russian revolutionary Trotsky was a roommate. He also claimed to have been forced to join the band of PanchoVilla, a bandit (also considered a revolutionary) who was active in the United States and Mexico at the beginning of the 20th century, and participated in a battle in Laredo. And saved 400 villagers. Weihai Xinghaiyuan Fishing & Netting Tackle Co.,Ltd. , https://www.yesonagri.com
