These miniature scenes are of a large embalming workshop of Dynasty 21, about 1085 BC in Egypt. As more and more people were mumified, the process must have become more like an essembly line. This period was the last before a general decline in the elbalmer's art which took place in Dynasty 22.
After the necessary prayers, an incision on the left side of the abdomen was made. The viscera (internal organs) were removed and dried, rinsed, bandaged and then placed in canopic jars or parcels which were placed with the body. These canopic jars would be decorated with the images of the "four sons of Horus". From the 18th Dynasty onwards, the stoppers of canopic jars were fashioned into the forms of the heads of each of the four gods.
