A mummy is a preserved corpse that, due to shielding from decomposition by either natural or artificial means, has retained its physical form. This can be achieved by exposing the body to extreme draught or cold, lack of oxygen, or use of chemicals.
The best-known mummies are those that have been embalmed with the specific purpose of preservation, particularly those in ancient Egypt. Egyptians believed the body was home to a person's Ka which was essential in one's afterlife.
Mummies formed as a result of naturally occurring environmental conditions, such as extreme cold (Ötzi the Iceman), acid (Tollund Man) or desiccating dryness have been found all over the world. Some of the best-preserved mummies formed under natural conditions date from the Inca period in Peru.
The word "mummy" is thought to be derived from the Arabic word mumiyah, which means bitumen. Because of the blackened skin of unwrapped mummies, bitumen was once thought to be used extensively in ancient Egyptian embalming procedures. Another possible source for the name is the Egyptian Coptic word mum, for wax of which the use in Egyptian embalming was in fact documented.
Mummies in Ancient Egypt
In Egypt, the dead were originally not mummified with the extensive process that happened during the first dynasty. The dead were originally buried in reed caskets in the sand. The searing hot sand caused the remains to dry quickly, preventing decomposition. After a while, though, they started constructing wooden tombs, and the extensive process of mummification was made so that the bodies would not decompose in the afterlife. The mummified individual was placed at his/her final resting place through a set of rituals and protocol.
The earliest 'mummified' individual dates back to approximately 3300 BC, although it is not a 'true' mummy. The body is on display in the British Museum and has been given the nickname of 'Ginger' because he has red hair. Ginger was buried in the hot desert sand with maybe some stones piled on top to prevent the corpse being eaten by jackals. The hot, dry conditions desiccated the body, preventing the muscle and soft tissues from decaying. Ginger was buried with some pottery vessels, which would have held food and drink to sustain him on his long journey to the other world. There are no written records of the religion or gods from that time, and it is not known if it was the intention of the ancient Egyptians that the deceased were being preserved.
However, from the First dynasty onwards, the ancient Egyptians were trying preserve the bodies of the death, so their spirit had a body to guide them to the afterlife.
Egyptian mummification process
Embalmers were given the task to preserve the deceased. Not only did they have to have knowledge of human anatomy, they also had to perform rituals at several stages during the process.
A typical mummification took 70 days in which craftsmen raced to finish the tomb.
The first step in a mummification was the removal of all internal organs which were prone to rapid decay. The brain was removed by breaking the bone at the end of the nose with a chisel and inserting a special hook up the nostrils and into the skull.
Embalmers also removed the stomach, liver, lungs and intestines through a small incision on the left side of the abdomen. Only the heart was left in place. The organs which were removed from the abdomen were stored in so called canopic jars, modelled after the four sons of Horus who would protect the organs, and placed in the tomb during the burial ritual. In later dynasties, these organs were treated and wrapped and returned to the body, but unused canopic jars continued to be placed into tombs. The incision was covered with a metal plate bearing the Eye of Horus (wedjat) which symbolically healed it.
Finally, the body was wrapped in large amounts of linen, some of which contained spells to help the deceased in their passage to the afterlife. After several stages of wrapping, the body would also be coated in warm resin, before wrapping was continued.
To further protect the deceased, magical amulets were placed on specific parts of the body between the layers of wrappings. These included:
Egyptian burial rituals
Finally, the mummy would be interred in varying ways that were dictated by the social status of the deceased. Relatively low-status individuals would simply be mummified and laid in a simple tomb or on a ledge in a larger tomb. Higher-status individuals would be interred in an elaborately decorated case, though perhaps not a stone sarcophagus. The highest-status individuals, such as pharoahs, would be interred in a set of nesting mummy cases and sarcophagi, which were often extremely elaborate.
Mummies in other civilizations
A number of other civilizations are known to have practised the art of mummification.
- Incas, whose practices were also adopted by Chachapoyas (which were conquered by the Incas).
- Tibetans, who reserved this honor for people who reached a highest level of enlightenment.
An ancient mummy dubbed the "handsome Yingpan man" was found in China's remote northwest province of Xinjiang. Archaeologists from the Xinjiang Archeological Institute found the mummified body when they opened a coffin in a graveyard dating back 1,900 years, according to Xinhua news agency. The mummy had thick brown hair, a shrunken face and body, and gray and brown skin. Its beard, eyebrows and eyelashes were clearly discernible and its clothes were intact and retained their bright color.
The mummified man, believed to have lived during the Eastern Han Dynasty (25-220 AD), was 1.8 meters (nearly six feet) tall and might have died at about 25 years of age. His coffin which had colorful paintings on the outside was discovered together with over 150 ancient tombs dating back to the Eastern Han Dynasty at Yingpan near Lop Nur in the Xinjiang Uighur Autonomous Region. This coffin along with five others had been shipped to Urumqi, the regional capital, and were kept in the institute, unopened, for three years. The mummy is believed to be significant for the study of economic and cultural exchanges between China and Western countries in ancient times.
The "handsome Yingpan man" is thought to be comparable to the "beautiful Loulan woman," a 3,800-year-old female mummy discovered in 1980 at the Tiebanhe Delta , about 200 kilometers east of Yingpan, said the report. Loulan was an ancient kingdom along China's Silk Road in Xinjiang.
Mummies in modern times
Mummies have been an object of intense interest in the West since archaeologists began finding them in large numbers. 19th century aristocrats would often entertain themselves by buying mummies, having them unwrapped, and holding observation sessions. These sessions destroyed several mummies, because the exposure to the air caused them to desintegrate.
Mummies were also believed to have medicinal properties, and were sold as pharmaceuticals in powdered form. However, they were not used as fuel for steam locomotives, and the idea that they were came from a joke by Mark Twain. However, during the First World War, mummy wrapping linens were manufactured into paper.
During the 20th century, horror films and other mass media popularized the notion of a curse associated with mummies. Most famous among these are the 1932 film "The Mummy" starring Boris Karloff and a 1999 film by the same name. This more or less facetious belief probably stems in part from the supposed curse on the tomb of Tutankhamun.
Science has also taken notice of mummies. Dr. Bob Brier, an Egyptologist, has been the first modern scientist to successfully recreate a mummy using the Egyptian method. Mummies have been used in medicine, to calibrate CAT scan machines at levels of radiation that would be too dangerous for use on living people. In fact, mummies can be studied without unwrapping them using CAT scan and X-ray machines to form a picture of what's inside.
They have been very useful to biologists and anthropologists, as they have provided a wealth of information about the health and life expectancy of ancient peoples. In particular, mummies have demonstrated that even 5,000 years ago, humans were anatomically indistinguishable from their present-day counterparts. This has had important repercussions for the study of human evolution.
Egyptian mummies were much sought-after by museums worldwide in the 19th and early 20th centuries and many exhibit mummies today. Notably fine examples are exhibited at the Egyptian Museum in Cairo, at the Ägyptisches Museum in Berlin, and at the British Museum in London. The Egyptian city of Luxor is also home to a specialised Mummification Museum.
