The brain has always been looked upon with reverence and awe for its power and capacity of conscious thought… right? Absolutely not. Not only is the brain the coolest thing in science (no bias, I swear) but historically it has been neglected or set aside as the “housing of the soul.” Well, that’s irritating.
So let’s start back in ye’ olden days of the pharaohs. It seems the Egyptians fall into a weird category of belief. They recognized the problems that would arise from head wounds but ignored it in terms of thought and consciousness. During the mummification process they would enter the nasal cavity, break through the thin-layered ethmoid bone, and draw out the contents of the skull. We’ve all heard this spiel since elementary school. The important parts to ask though are the why and how.
The why seems relatively straight forward. It was removed along with all the other organs excluding the heart to prepare the dead for their afterlife. The heart was left in place to be judged in Duat, the Egyptian underworld. Under supervision of Anubis, the heart was weighed against Ma’at’s feather of truth. The Declaration of Innocence: Spell 125 details a 42-part moral system which they were judged upon – similar to that of the 10 Commandments of Christianity but 2000 years prior (coincidence? >_>). If the heart was found to be unworthy it was eaten by the “devourer”, Ammut. If not, they proceeded to Aaru, the heavenly reed field.
That’s neat and all, but it’s not the whole story. Only 50% of recovered mummy skulls had the brain removed prior to mummification. In addition, the eyes had also been removed and replaced with various materials. Why? Because they rot and stay moist. The whole point of mummification is to remove as much water as possible to preserve the remaining tissue. The body needed to stay as recognizable as possible; I’ll explain in a minute. An example concoction used as a dehydrant consisted of 84.7% sodium carbonate or bicarbonate, 1.5% sodium chloride, and 13.8% sodium sulphate. While this prevents most bacterial decay it doesn’t stop it all. The brain and eyes start to leak fluid and rot. Quick fix? Take them out. Sure, it’s a little more difficult than the other organs, but it works better in the long-run. A dry mummy is a happy mummy.
Another key part is how the brain was removed. Mummification was usually performed in a manner that minimized cosmetic damage as it was believe the soul (the Ba) needed to recognize the body to return to it every night. The common belief of the process behind it seems to be a gross misconception. It is largely held that the brain was sucked out, scooped out with a hook or some variation thereof. For the most part, this is untrue. The tool used did indeed have a hook but it did not function in that fashion. The viscosity of the brain allowed it to stick to the entire tool. So, as the tool would be drawn out it would bring brain with it. With repeated entry from the tool the inside tissue would begin to liquefy and eventually could be poured out of the nasal cavity.
The Egyptians were pioneers of the medical realm. They were even recognized by Homer in the Odyssey: “In Egypt, the men are more skilled in medicine than any of human kind.” The Edwin Smith Surgical Papyrus details a great many of their accomplishments along with a few of their more… unique practices. Maybe with a bit more time they could have perfected the art of medicine a little more. Until next time, remember to “pour milk into both ears” for a wounded temple.
