Embalming – Specific substances for certain parts of the body
Analyzing the chemical residue in the vessels has now allowed the molecular remains of those substances that were once used in a given vessel to be isolated and identified. As the mystery unraveled, there were a number of surprises. Maxime Rageot, archeologist at the University of Tübingen and head of the analysis project, reveals one of them: “The substance labeled by the ancient Egyptians as antiu has long been translated as myrrh or frankincense. But we have now been able to show that it is actually a mixture of widely differing ingredients that we were able to pick apart with the aid of gas chromatography/mass spectrometry.” The antiu used in Saqqara was a blend of cedar oil, juniper/cypress oil and animal fats.
These insights facilitate a re-reading of familiar texts about ancient Egyptian embalming. Comparing the identified substances with the labels on the vessels has now, for the first time, enabled the team of researchers to determine exactly what substances were used to embalm certain parts of the body. Pistachio resin and castor oil, for example, were used only for the head. “What really surprised us was that the bulk of the substances used for embalming were not from Egypt itself. Some of them were imported from the Mediterranean region and even from tropical Africa and Southeast Asia,” says LMU archeologist Philipp Stockhammer, who funded the research with his ERC Starting Grant.
Besides pistachio resin, cedar oil and bitumen – all probably from the Levant – the researchers also found residues of dammar gum and elemi resin. These two substances in particular show how globalized trade relationships had already become nearly 3,000 years ago. While the resin of the elemi tree came to Egypt from tropical Africa or Southeast Asia, the dammar tree to this day still grows solely in tropical Southeast Asia. Tremendous effort thus evidently went into sourcing very specific chemical substances for the embalming process. “Ultimately, Egyptian mummification probably played an important role in the early emergence of global networks,” Rageot says. “Large quantities of these exotic resins were needed.” Stockhammer agrees: “Thanks to all the inscriptions on the vessels, we will in future be able to further decipher the vocabulary of ancient Egyptian chemistry that we did not sufficiently understand to date.”
