A mummy is a corpse whose skin and organs have been preserved by either intentional or incidental exposure to chemicals, extreme coldness, very low humidity, or lack of air when bodies are submerged in bogs. Presently, the oldest discovered (naturally) mummified human corpse was a decapitated head dated as 6,000 years old and was found in 1936.[1] The most famous Egyptian mummies are those of Seti I and Rameses II (13th century BC), though the earliest known Egyptian mummy, nicknamed 'Ginger' for its hair colour, dates back to approximately 3300 BC.
Mummies of humans and other animals have been found throughout the world, both as a result of natural preservation through unusual conditions, and as cultural artifacts to preserve the dead. Over one million animal mummies have been found in Egypt, many of which are cats. It takes 70 days to bury them and finish doing all of their work.

Etymology

The English word mummy is derived from medieval Latin mumia, a borrowing of the Persian word mūm (موم), which means "bitumen". Because of the blackened skin bitumen was once thought to be used extensively in ancient Egyptian embalming procedures. (See also: Mummia.)

The Egyptian mummification process

The earliest known Egyptian mummy, nicknamed 'Ginger' for its hair colour, dates back to approximately 3300 BC. Currently on display in the British Museum, Ginger was discovered buried in hot desert sand. Desert conditions can naturally preserve bodies so it is uncertain whether the mummification was intentional or not. However, since Ginger was buried with some pottery vessels it is likely that the mummification was a result of preservation techniques of those burying him. Stones might have been piled on top to prevent the corpse from being eaten by jackals and other scavengers and the pottery might have held food and drink which was later believed to sustain the deceased during the journey to the other world.
From the Middle Kingdom onwards, embalmers used salts to remove moisture from the body. The salt-like substance natron dried out and preserved more flesh than bone. Once dried, mummies were ritualistically anointed with oils and perfumes. The emptied body was then covered in natron, to speed up the process of dehydration and prevent decomposition. Natron dries the body up faster than desert sand, preserving the body better. Often finger and toe protectors were placed over the mummy's fingers and toes to prevent breakage. They were wrapped with strips of white linen that protected the body from being damaged. After that, they were wrapped in a sheet of canvas to further protect them. Many sacred charms and amulets were placed in and around the mummy and the wrappings. This was meant to protect the mummy from harm and to give good luck to the Ka of the mummy. Once preserved, they were laid to rest in a sarcophagus inside a tomb, where it was believed that the mummy would rest eternally. In some cases the mummy's mouth would later be opened in a ritual designed to symbolize breathing, giving rise to legends about revivified mummies.

Scientific study of Egyptian mummies

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 specialized Mummification Museum. The mummified remains of what turned out to be Rameses I ended up in a Daredevil Museum near Niagara Falls on the United States–Canada border; records indicate that it had been sold to a Canadian in 1860 and exhibited alongside displays such as a two-headed calf for nearly 140 years, until a museum in Atlanta, Georgia, which had acquired the mummy along with other artifacts, determined it to be royal and returned it to Egypt's Supreme Council of Antiquities. It is currently on display in the Luxor Museum.
More recently, science has also taken interest in mummies. Dr. Bob Brier, an Egyptologist, has been the first modern scientist attempted to recreate a mummy using the ancient 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 digital image 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 people. In 2008, the latest generation CT scanners (64- and 256-slice Philips at the University of Chicago) were used to study Meresamun, a temple singer and priestess at the Temple of Amun whose mummy now resides at the Oriental Institute of Chicago.
Scientists interested in molecular cloning the DNA of mummies have reported findings of analysable DNA in an Egyptian mummy dating to circa 400 BC.[4] Although analysis of the hair of Ancient Egyptian mummies from the Late Middle Kingdom has revealed evidence of a stable diet,[5] Ancient Egyptian mummies from circa 3200 BC show signs of severe anaemia and hemolytic disorders.

Natural mummies

Mummies that are formed as a result of naturally-occurring environmental conditions, such as extreme coldness (Ötzi the Iceman, the Ice Maiden, the Llullaillaco child mummies), acid (Tollund Man), salinity (Salt Man), or desiccating dryness (Tarim mummies), have been found all over the world. More than a thousand Iron Age corpses, so called bog bodies, have been found in bogs in northern Europe, such as the Yde Girl and the Lindow Man.[7] Natural mummification of other animal species also occurs; this is most common in species from shallow saline water environments, especially those with a body structure which is particularly favourable to this process, such as seahorses and starfish. Old mummies such as the dinosaurs Leonardo, Dakota, and the Trachodon mummy in America were very valuable discoveries.

Mummies in fiction

Mummies are commonly featured in horror genres as undead creatures. During the 20th century, horror films and other mass media popularized the notion of a curse associated with mummies. One of the earliest appearances was The Jewel of Seven Stars, a horror novel by Bram Stoker first published in 1903 that concerned an archaeologist's plot to revive an ancient Egyptian mummy. This book later served as the basis for the 1971 film Blood from the Mummy's Tomb.
Films representing such a belief include the 1932 movie The Mummy starring Boris Karloff as Imhotep; four subsequent 1940s' Universal Studios mummy films which featured a mummy named Kharis, who also was the title mummy in The Mummy, a 1959 Hammer remake of The Mummy's Hand and The Mummy's Tomb; and a remake of the original film that was released in 1999 (and later spawned two direct sequels and a spinoff movie). The belief in cursed mummies probably stems in part from the supposed curse on the tomb of Tutankhamun. In 1979, the American Broadcasting Company aired a TV holiday show, The Halloween That Almost Wasn't, in which a mummy from Egypt (Robert Fitch) arrived at Count Dracula's castle without speaking.
The 1922 discovery of Tutankhamun's tomb by archaeologist Howard Carter brought mummies into the mainstream. Slapstick comedy trio the Three Stooges humorously exploited the discovery in the short film We Want Our Mummy, in which they explored the tomb of the midget King Rutentuten (and his Queen, Hotsy Totsy). A decade later, they played crooked used chariot salesmen in Mummy's Dummies, in which they ultimately assisted a different King Rootentootin (Vernon Dent) with a toothache.
