Why does masked dancing play an important role in African dance?

Masked dancing plays an important role in African dance. Masked dancing originated from religious sacrifices, and there are many images of masked dancing on murals. Masked dancing is a traditional African dance. All sacrificial dances in the Sahara region generally have masks and different types of faces, which are classified according to the role of worshipping God. Some scholars have investigated and analyzed the masks used in African dances, saying: "They are related to people engaged in farming. Among the ancient humans in Africa, the earliest invention and use of masks seems to be related to the purification ceremony. At that time, there was no ambivalence about nature. People think that nature is fundamentally friendly. However, farming is an invasion of nature, and this invasion has to pay a price. However, no matter how to compensate and atone, people can't be freed from the punishment of nature. Therefore, the customs and practices of masked society coincide with the appearance of death. The purpose of these customs and practices is to clean the earth and defile those who blaspheme her. "
