In some cases, the innards were stored in specially prepared canopic jars.
The body was then carefully washed externally with water, and with cedar oil on the inside.
Cavities, such as the head and abdomen, were filled with spices and the incisions were stitched up.
The entire body was then steeped in a fusion of nitre for 40 days, and once complete, it was wrapped in bandages of fine linen.
Professor Meyer said: “Layers of cloth, plastered with lime on the inside, were next placed on the body in a damped condition, fitting exactly to its shape.
“These layers were put on in sufficient numbers to make a thick case, which, when it was finished, was taken off until it became hardened when it was replaced, and sewed up at the back.
