Ancient Egyptian manual reveals new details about mummification

Ancient Egyptian manual reveals new details about mummification
2021-02-26
(Press-News.org) Based on a manual recently discovered in a 3,500-year-old medical papyrus, University of Copenhagen Egyptologist Sofie Schiødt has been able to help reconstruct the embalming process used to prepare ancient Egyptians for the afterlife. It is the oldest surviving manual on mummification yet discovered.

In ancient Egypt, embalming was considered a sacred art, and knowledge of the process was the preserve of very few individuals. Most secrets of the art were probably passed on orally from one embalmer to the other, Egyptologists believe, so written evidence is scarce; until recently, only two texts on mummification had been identified.

Egyptologists were therefore surprised to find a short manual on embalming in a medical text that is primarily concerned with herbal medicine and swellings of the skin. The manual has recently been edited by University of Copenhagen Egyptologist Sofie Schiødt:

- Many descriptions of embalming techniques that we find in this papyrus have been left out of the two later manuals, and the descriptions are extremely detailed. The text reads like a memory aid, so the intended readers must have been specialists who needed to be reminded of these details, such as unguent recipes and uses of various types of bandages. Some of the simpler processes, e.g. the drying of the body with natron, have been omitted from the text, Sofie Schiødt explains. She adds:

- One of the exciting new pieces of information the text provides us with concerns the procedure for embalming the dead person's face. We get a list of ingredients for a remedy consisting largely of plant-based aromatic substances and binders that are cooked into a liquid, with which the embalmers coat a piece of red linen. The red linen is then applied to the dead person's face in order to encase it in a protective cocoon of fragrant and anti-bacterial matter. This process was repeated at four-day intervals.

Although this procedure has not been identified before, Egyptologists have previously examined several mummies from the same period as this manual whose faces were covered in cloth and resin. According to Sofie Schiødt, this would fit well with the red linen procedure described in this manuscript.

Four was the key number

The importance of the Papyrus Louvre-Carlsberg manual in reconstructing the embalming process lies in its specification of the process being divided into intervals of four, with the embalmers actively working on the mummy every four days.

- A ritual procession of the mummy marked these days, celebrating the progress of restoring the deceased's corporeal integrity, amounting to 17 processions over the course of the embalming period. In between the four-day intervals, the body was covered with cloth and overlaid with straw infused with aromatics to keep away insects and scavengers, Sofie Schiødt says.

The Papyrus Louvre-Carlsberg

The manuscript, which Sofie Schiødt has been working on for her PhD thesis, is the Papyrus Louvre-Carlsberg - so called because one half of the papyrus belongs to the Louvre Museum in Paris and the other half is part of the University of Copenhagen's Papyrus Carlsberg Collection. The two parts of the papyrus originally belonged to two private collectors, and several sections of it are still missing. Based on the palaeography, that is, the sign forms, the six metre long papyrus is dated to approximately 1450 BC, which means that it predates the only two other examples of embalming texts by more than a thousand years.

The bulk of the papyrus, which is the second-longest medical papyrus surviving from ancient Egypt, deals with herbal medicine and skin illnesses. Specifically, it contains the earliest-known herbal treatise, which provides descriptions of the appearance, habitat, uses, and religious significance of a divine plant and its seed as well as a lengthy treatise on swellings of the skin, which are seen as illnesses sent forth by the lunar god Khonsu.

The papyrus is planned for publication in 2022 as a collaboration between the Louvre Museum and the Papyrus Carlsberg Collection. If you are interested in a copy of Sofie Schiødt's PhD thesis "Medical Science in Ancient Egypt: A translation and interpretation of Papyrus Louvre-Carlsberg (PLouvre E 32847 + PCarlsberg 917)", which she defended 8 February 2021, please contact her at zcq348@hum.ku.dk.

The embalming process

The embalming, which was performed in a purpose-built workshop erected near the grave, took place over 70 days that were divided into two main periods - a 35-day drying period and a 35-day wrapping period.

During the drying period, the body was treated with dry natron both inside and outside. The natron treatment began on the fourth day of embalming after the purification of the body, the removal of the organs and the brain, and the collapsing of the eyes.

The second 35-day period was dedicated to the encasing of the deceased in bandages and aromatic substances. The embalming of the face described in the Papyrus Louvre-Carlsberg belonged to this period.

The entire 70-day embalming process was divided into intervals of 4 days, with the mummy being finished on day 68 and then placed in the coffin, after which the final days were spent on ritual activities allowing the deceased to live on in the afterlife.

Dinosaur species: 'Everyone's unique'

Dinosaur species: Everyones unique
2021-02-26
"Everyone's unique" is a popular maxim. All people are equal, but there are of course individual differences. This was no different with dinosaurs. A study by researchers at the University of Bonn and the Dinosaur Museum Frick in Switzerland has now revealed that the variability of Plateosaurus trossingensis was much greater than previously assumed. The paleontologists examined a total of 14 complete skulls of this species, eight of which they described for the first time. The results have now been published in the scientific journal "Acta Palaeontologica Polonica". Plateosaurus lived during the Late Triassic, about 217 to 201 million years ago. "With well over 100 skeletons, some of them completely preserved, ...

How photoblueing disturbs microscopy

How photoblueing disturbs microscopy
2021-02-26
The latest developments in fluorescence microscopy make it possible to image individual molecules in cells or molecular complexes with a spatial resolution of up to 20 nanometres. However, under certain circumstances, an effect occurs that falsifies the results: the laser light used can cause very reactive oxygen molecules to form in the sample. These can then damage the fluorescent dyes used to such an extent that they no longer fluoresce. Among microscopy experts, this effect is known as photobleaching. However, various fluorescent dyes can also be transformed by photobleaching so that they absorb light of shorter wavelengths. "A previously red fluorescent dye then glows green. Its fluorescence ...

Warming may promote spread of invasive blue catfish

Warming may promote spread of invasive blue catfish
2021-02-26
A study by researchers at William & Mary's Virginia Institute of Marine Science suggests that continued warming of Atlantic coastal waters may enhance the spread of invasive blue catfish within the Chesapeake Bay and other estuaries along the U.S. East Coast. The research, by Drs. Vaskar Nepal and Mary Fabrizio of VIMS, appeared in a recent issue of PLOS ONE. It builds on an earlier study by the two authors showing that blue catfish can better tolerate salinity spikes than most freshwater fishes, and thus may be able to expand their range downstream into mainstem Chesapeake waters, and from there into new Bay tributaries and even Delaware Bay. "Blue cats" were introduced to tidal freshwater stretches of the James, York, and Rappahannock rivers during the 1970s and 1980s ...

Discovery: Neanderthal-derived protein may reduce the severity of COVID-19

2021-02-26
Researchers at the Lady Davis Institute (LDI) at the Jewish General Hospital have discovered that increased levels of the protein OAS1 are associated with reduced mortality and less severe disease requiring ventilation among patients with COVID-19. Using drugs that boost OAS1 levels could be explored to try to improve these outcomes. The findings are published today in Nature Medicine. "Our analysis shows evidence that OAS1 has a protective effect against COVID-19 susceptibility and severity," explains Dr. Brent Richards, a senior investigator at the LDI's Centre for Clinical Epidemiology and Professor of Medicine, Human Genetics, Epidemiology and Biostatistics at McGill University. "This is a very ...

Pioneering prehistoric landscape reconstruction reveals early dinosaurs lived on tropical islands
2021-02-26
A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago. The research, led by the University of Bristol, examined hundreds of pieces of old and new data including historic literature vividly describing the landscape as a "landscape of limestone islands like the Florida Everglades" swept by storms powerful enough to "scatter pebbles, roll fragments of marl, break bones and teeth." The evidence was carefully compiled and digitised so it could be used to generate for the first time ...

Statin use associated with increased survival in severe COVID-19

2021-02-26
NEW YORK, NY (Feb. 26, 2021)--People who took statins to lower cholesterol were approximately 50% less likely to die if hospitalized for COVID-19, a study by physicians at Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian has found. "Our study is one of the larger studies confirming this hypothesis and the data lay the groundwork for future randomized clinical trials that are needed to confirm the benefit of statins in COVID-19," says Aakriti Gupta, MD, a cardiologist at NewYork-Presbyterian/Columbia University Irving Medical Center and one of the co-lead authors of the study. "If their beneficial effect bears out in randomized clinical trials, statins could potentially prove to be a low-cost and effective therapeutic ...

Male lyrebirds create an 'acoustic illusion' to snare potential mates

Male lyrebirds create an acoustic illusion to snare potential mates
2021-02-26
Ithaca, NY--Famous for their uncanny ability to imitate other birds and even mechanical devices, researchers find that Australia's Superb Lyrebird also uses that skill in a totally unexpected way. Lyrebirds imitate the panicked alarm calls of a mixed-species flock of birds while males are courting and even while mating with a female. These findings are published in the journal Current Biology. "The male Superb Lyrebird creates a remarkable acoustic illusion," says Anastasia Dalziell, currently a Cornell Lab of Ornithology Associate and recent Cornell Lab Rose Postdoctoral Fellow, now at the University of Wollongong, Australia. "Birds gather in mobbing flocks and the ruckus they make is a potent cue of a predator nearby. The ...

Could a common barnacle help find missing persons lost at sea?

Could a common barnacle help find missing persons lost at sea?
2021-02-26
A common barnacle could be used to help trace missing persons lost at sea, according to research by UNSW Science. Researchers from the Centre for Marine Science and Innovation have developed an equation that can estimate the minimum time an object has spent drifting at sea by counting the number of Lepas anserifera attached to the object. They also developed an equation which can help plot possible drift paths of a missing boat. "We saw this opportunity that Lepas could possibly fill in this gap in that marine forensic process and possibly contribute (to finding missing people)," study lead author Thomas ...

Development of an electroceutical to drastically reduce high-risk, preterm labor
2021-02-26
Preterm labor comprises 12.7% of all pregnancies. Although the overall rate of pregnancy is decreasing, the occurrence of premature birth due to preterm labor in south korea has been increasing over the past 7 years. Not only is preterm birth accountable for about a half of all neonatal mortality cases, the neurological deficits in surviving premature infants often lead to problems later in life, such as developmental disorders and respiratory complications. Currently, preterm labor is detected only when expecting mothers experience abnormal symptoms, or when they undergo a routine test like abdominal ultrasound or a laboratory test for ...
