Making a mummy requires many steps, and putting a portrait on the face is just one of them. The first is to clear the brain. The priest will use a special spike to nail it from Pharaoh's nostril into the cranial cavity. Then, stir with all the strength of the wild until the brains are completely broken and flow out of the nostrils. In the eyes of ancient Egyptians, the brain was the most useless. You don't need to keep them. You can throw them away.
Fill the brain hole. It's not good to have an empty head, is it Then the priest will pour resin into his nose. Fill the hollowed-out head, and the priest will put some special spices and medicines into the inner head. One is to prevent the brain from deforming, and the other is to prevent the brain from rotting.
Empty your body again. This is a key step in mummification! After death, there are many digestive enzymes and bacteria in the internal organs, but they are alive. They can quickly devour the whole body from the inside, so the priests have to cut the Pharaoh's body with a knife and take out all the internal organs such as liver, intestine, stomach and lungs. Except the heart! Their biggest taboo is heartbreak. Because they believe that the soul lives in the heart, and if the heart is gone, Pharaoh can't be resurrected.
There are also pickled viscera, fragrant bath, salt bath, essential oil massage, and finally plastic surgery. In order to prevent facial decay and deformation, the priests will first apply turpentine to the face of the corpse. After that, the makeup artist used milk, wine, spices, beeswax, turpentine and tar to make up his body, but he could not recover his lost face. In order that Pharaoh would not be scared to death by his appearance when he was resurrected, they would put a mask on Pharaoh and put makeup on it.
