Mummification and the funerary trade

What is attested

Deliberate chemical treatment of the dead body in Egypt is older than the pharaonic state. Chemical analysis of the funerary textiles on Turin mummy S. 293, a body of about 3700–3500 BC probably from the Gebelein region, identified a compound preparation impregnating the wrappings: a plant oil, a heated conifer resin, an aromatic plant extract, and a plant gum or sugar. The proportions are broadly comparable to balms used two and a half millennia later. Earlier analysis by the same research group of textile fragments from Predynastic burials at Mostagedda pointed the same way. This matters because it detaches the origin of embalming from the tidy story in which Egyptians noticed that desert sand dried out bodies and then set out to imitate the effect artificially. Something recognisable as a recipe existed before there was a unified Egypt to have a state religion.

By the Old Kingdom the operation had acquired its defining surgical element. When George Reisner's team opened the shaft tomb G 7000 X at Giza in 1925, the alabaster chest inside contained viscera packets in what analysis indicated was a natron solution — the earliest widely cited evidence for evisceration and separate treatment of the organs, associated with Hetepheres I of the Fourth Dynasty. The identification of the liquid as a natron solution rests on a field observation made in 1925 and has since been questioned, so the superlative belongs to the citation history as much as to the object. From the Middle Kingdom onwards the fuller procedure is legible directly in the bodies: removal of the brain through the nose, an incision in the left flank, removal of lungs, liver, stomach and intestines with the heart normally left in place, desiccation with dry natron rather than a bath, packing, resinous coating, and layered bandaging with amulets set at prescribed points. Almost all of this is known from the products of the process — from radiography, CT and autopsy of mummies — and not from any Egyptian instruction text of the period in question.

Since 2018 the chemistry has become specific rather than general. A German–Egyptian mission led by Ramadan Hussein excavated a Twenty-sixth Dynasty embalming workshop in a shaft complex at Saqqara, containing ceramic vessels inscribed with the names of their contents or their intended use. Analysis of thirty-one of these, published by Rageot and colleagues in Nature in 2023, allowed Egyptian substance names to be matched against identified compounds — with results that overturned some standard translations, since antiu, conventionally rendered myrrh or incense, corresponded to conifer-based mixtures, and sefet to an unguent with plant additives. Different preparations were used for the head and for the wrappings. The substances included elemi and dammar, from tropical forests in Asia and Africa, alongside Pistacia and conifer products from around the Mediterranean. Embalming at Saqqara in the seventh and sixth centuries BC was drawing on long-distance trade networks. That is a statement about one workshop in one period; it is not evidence for what a Middle Kingdom embalmer used.

Egyptian instructions do survive, but there are very few and their dates are decisive. The most important is a section on the reverse of Papyrus Louvre-Carlsberg, a medical manuscript of roughly 1450 BC split between the Louvre and the Papyrus Carlsberg Collection in Copenhagen, identified and published by Sofie Schiødt: it lays out a seventy-day schedule divided into a drying half and a wrapping half, structured in four-day intervals, and it includes instructions for treating the face with a piece of red linen coated in an aromatic plant-based mixture. The other Egyptian technical texts — Papyrus Boulaq 3 and Papyrus Louvre 5158, the so-called Ritual of Embalming — are Roman-period copies which prescribe unguents and bandaging together with the words to be spoken over each stage. These are the practice described in its own language. None of them is a price list.

The commercial side is documented from the trade's own paperwork, and it is unambiguously an industry. The Ptolemaic Theban archives of the choachytes — the men and women responsible for the ongoing care of tombs and the pouring of libations for the dead — record the rights to serve particular tombs and families as heritable, divisible and saleable property. In the archive studied by Pestman and in the related Theban choachyte archives, these liturgies are sold between brothers, inherited by widows, sold on by wives, and fought over in court, in demotic and Greek documents spanning generations. Alongside the choachyte stood the paraschistes who made the incision, the taricheutes who did the salting and wrapping, and the nekrotaphos who handled burial. Mass production is visible in the goods too: Book of the Dead papyri survive with blank spaces where the purchaser's name was later inserted, sometimes in a different hand. The picture is of a service sector with specialised trades, transferable assets, and stock kept on the shelf.

How the rite worked

What follows is a modern composite reconstructed from bodies of many periods; no single body or text attests it in full, and the order of steps is inferred from the order in which materials were applied rather than observed being carried out. The brain was removed through the nostrils, an operation that leaves a broken ethmoid visible on CT; it was not preserved. An incision was cut in the left flank and the lungs, liver, stomach and intestines removed, treated separately, and stored in jars or, in later practice, wrapped in packages returned to the body cavity. The heart was normally left in place. The body was then desiccated with dry natron — a naturally occurring sodium carbonate and bicarbonate mixture collected from the Wadi Natrun and elsewhere — packed around and inside it rather than as a bath. Duration cannot be read off a body; the figure of roughly thirty-five days usually given for this stage comes from the drying half of the Louvre-Carlsberg schedule, not from the material. It was then cleaned, anointed and packed with linen, sawdust or resin to restore contour, the head treated with its own preparations, and wrapped in many layers with amulets placed at specified points. The Papyrus Louvre-Carlsberg schedule gives the whole a seventy-day frame, split evenly between drying and wrapping. Genesis 50:2–3, a Hebrew narrative composed outside Egypt, gives forty days for the embalming of Jacob and seventy days of Egyptian mourning: only the seventy-day figure overlaps with the Egyptian manual, and there it attaches to mourning rather than to the treatment of the body.

Practice varied by period, by region and by client, and the variation is not a simple curve of improvement and decline. Twenty-first Dynasty embalmers packed material subcutaneously through small incisions to restore the appearance of a living body, a technique not used before or much after. Late and Roman-period bodies are often heavily resinated, sometimes with elaborate external wrapping and gilding or a painted portrait panel over a body less carefully prepared beneath. Quality of preservation within any single period ranges enormously, and expensive burial does not reliably correlate with well-preserved tissue: some royal mummies are in worse condition than modest private ones.

The work happened in a dedicated place, described in Egyptian texts as the ibu, the tent or place of purification, and the wabet or per-nefer, the workshop where the treatment proper was carried out. The Saqqara shaft workshop gives that vocabulary a floor plan: a working space with its vessels labelled by content and use, set immediately above the burial shafts it served. Embalming debris was itself considered part of the burial and was deposited rather than discarded — the cache found in KV54 in the Valley of the Kings, containing natron bags, used linen, pottery and floral collars associated with the burial of Tutankhamun, is the physical residue of a single funeral.

On cost, the evidence is thin and specific rather than general. Ptolemaic and Roman contracts record fees paid to choachytes for the continuing care of named tombs, and the sale prices of liturgies appear in the demotic archives, but no Egyptian source sets out a general tariff for embalming. It is also essential to remember the base rate, which has to be inferred from cemeteries rather than counted. Simple pit burial at the desert edge, where the dry sand preserved bodies without intervention, is what excavated cemeteries show most of the dead receiving wherever the question has been examined, and mummification is concentrated in elite contexts — though the excavated sample is itself skewed and the proportion cannot be quantified. The practice widened over time; what it never becomes, on the evidence we have, is a documented national norm.
