We all know that death and taxes are unavoidable, but what about decomposition? The ancient Egyptians were determined to stop bodies from decomposing, and they went to great lengths to do so. But how successful were they in preserving bodies for thousands of years?
Our living cells are constantly renewing themselves. They use special enzymes to break down old parts and use the materials to build new ones. However, when someone dies, their cells stop renewing, but the enzymes keep breaking things down. This means that if you want to preserve a body, you have to act fast to stop these enzymes before they start breaking down the tissues.
The brain is one of the first parts to decay because neurons die quickly. According to the Greek historian Herodotus, the Egyptians started the mummification process by removing the brain through the nose. They then filled the skull with tree resins to prevent further decay.
While the brain decays quickly, the internal organs are even trickier. The liver, stomach, and intestines have digestive enzymes and bacteria that start breaking down the body from the inside. To prevent this, priests removed the lungs and abdominal organs first. They took special care with the heart because they believed it was the seat of the soul.
The organs were placed in jars filled with a natural salt called natron. Natron is a mix of soda ash and baking soda, which are great at killing bacteria and stopping the body’s enzymes from working. These salts can also turn fatty tissues into a hard, soapy substance, helping to keep the body intact.
After dealing with the organs, the priests filled the body cavity with natron and cleaned the skin to disinfect it. The body was then laid in a bed of natron for about 35 days to dry out the outer flesh. By the end of this period, the body was not rotten, but it didn’t smell pleasant either.
To finish the process, priests poured tree resin over the body, massaged it with a waxy mixture that included cedar oil, and wrapped it in linen. Finally, they placed the mummy in a series of nested coffins and sometimes in a stone sarcophagus.
So, how successful were the ancient Egyptians at preventing decay? While mummies are not complete human bodies since their brains and organs have been removed and much of their body mass has been drained, what remains is incredibly well-preserved. Even after thousands of years, scientists can study mummies to learn about causes of death and even extract DNA samples.
This research has uncovered fascinating information, such as the fact that air pollution was a problem in ancient Egypt, likely due to indoor fires used for cooking. Diseases like cardiovascular disease and tuberculosis were also common.
In the end, while the ancient Egyptians were quite successful at slowing down decay, decomposition, like death, is ultimately inevitable. Interestingly, when some mummies were transported, they were taxed as if they were salted fish!
Research the steps involved in the ancient Egyptian mummification process. Create a timeline that outlines each step, from the removal of the brain to the final wrapping in linen. Use images and descriptions to make your timeline visually engaging and informative.
Conduct a simple experiment to understand the role of enzymes in decomposition. Use fruit like bananas or apples and observe how they decompose over time. Document your observations and discuss how the ancient Egyptians might have countered these natural processes.
Learn about the significance of canopic jars in the mummification process. Design and create your own canopic jar using clay or other materials. Explain which organ your jar would protect and why it was important to the ancient Egyptians.
Investigate the properties of natron and its role in mummification. Create a small-scale experiment using baking soda and salt to preserve a piece of fruit or vegetable. Record the changes over a week and compare your results to the mummification process.
Work in groups to role-play an ancient Egyptian mummification ceremony. Assign roles such as priests, embalmers, and family members. Create a script that includes the steps of mummification and the beliefs associated with each step. Perform your ceremony for the class.

Death and taxes are famously inevitable, but what about decomposition? Ancient Egyptians went to great lengths to prevent decomposition. So, how successful were they? Living cells constantly renew themselves, and specialized enzymes decompose old structures, using the raw materials to build new ones. However, when someone dies, their cells can no longer renew themselves, but the enzymes continue to break everything down. Therefore, anyone looking to preserve a body needed to act quickly to counteract those enzymes before the tissues began to deteriorate.
Neurons die quickly, making the brain difficult to preserve, which is why, according to Greek historian Herodotus, the mummification process began with the removal of the brain through the nose, followed by the introduction of tree resins into the skull to prevent further decomposition. While the brain decays first, the internal organs can pose a greater challenge. The liver, stomach, and intestines contain digestive enzymes and bacteria that start breaking down the body from the inside after death. As a result, the priests removed the lungs and abdominal organs first. Although it was tricky to extract the lungs without harming the heart, the heart was treated with special care as it was believed to be the seat of the soul.
The visceral organs were placed in jars filled with a naturally occurring salt called natron. Natron can prevent decay by killing bacteria and inhibiting the body’s natural digestive enzymes. It is primarily a mixture of two alkaline salts, soda ash and baking soda, which are particularly effective against bacteria. These alkaline salts can also transform fatty membranes into a hard, soapy substance, helping to maintain the structure of the corpse.
After addressing the internal organs, the priests filled the body cavity with natron and cleaned the skin to disinfect it. The corpse was then placed in a bed of natron for about 35 days to preserve its outer flesh. By the end of this period, the alkaline salts had absorbed fluid from the body, forming hard clumps. While the corpse was not putrid, it did not have a pleasant smell. To seal the body, priests poured tree resin over it, massaged it with a waxy mixture that included cedar oil, and wrapped it in linen. Finally, they placed the mummy in a series of nested coffins and sometimes in a stone sarcophagus.
So, how successful were the ancient Egyptians at preventing decay? On one hand, mummies are not intact human bodies; their brains have been removed, their organs have been treated, and a significant portion of their body mass has been drained. However, what remains is remarkably well-preserved. Even after thousands of years, scientists can perform autopsies on mummies to determine causes of death and potentially isolate DNA samples. This research has revealed new information, such as the fact that air pollution was a significant issue in ancient Egypt, likely due to indoor fires used for baking. Cardiovascular disease and tuberculosis were also common.
In conclusion, while ancient Egyptians were somewhat successful at evading decay, like death, decay is ultimately inevitable. Interestingly, when some mummies were transported, they were taxed as salted fish.
