The funeral preparations for ancient Egyptian dead were extensive. Tomb walls were often elaborately painted and inscribed with scenes and objects deemed desirable for the afterlife. Votive objects, furniture, clothing, jewelry, and importantly, food including bread, cereals, fruit, jars of wine, beer, oil, meat, and poultry were included in the burial goods. An intriguing feature of the meat and poultry produced for the deceased from the highest levels of Egyptian society was that they were mummified to ensure their preservation. However, little is known about the way they were prepared, such as whether balms were used, and if they were used, how they compared with those applied to human and animal mummies? We present herein the results of lipid biomarker and stable carbon isotope investigations of tissues, bandaging, and organic balms associated with a variety of meat mummies that reveal that treatments ranged from simple desiccation and wrapping in bandages to, in the case of the tomb of Yuya and Tjuia (18th Dynasty, 1386-1349 BC), a balm associated with a beef rib mummy containing a high abundance of Pistacia resin and, thus, more sophisticated than the balms found on many contemporaneous human mummies.food mummies | pharaohs | Egypt | triterpenoids | fatty acyl lipids F ood to sustain the deceased in the afterlife was perhaps the most important item in a burial and has been found in interments from the earliest periods (3300 BC) to the latest (fourth century AD). The burial of King Tutankhamun (died c. 1323 BC) comprised 48 carved wooden cases containing a variety of joints from cattle and poultry (1, 2). Virtually all of the food found in these tombs was preserved through dehydration, save for the meat, as untreated meat would not last more than a few hours in the Egyptian heat. A solution to preserving meat in the burials would have been to preserve it in the same manner as human mummies. Indeed, "meat" or "victual" mummies have been found in many high status tombs (3). Meat mummies are but one type of animal mummy produced by the Egyptians, the others including votives, pets to be left in the tomb with their owner, and sacred animals, such as the Apis bull (1, 4, 5).Hundreds of examples of meat mummies are known from ancient Egypt (see appendix II in ref. 1). Until recently, these had been neglected as objects of study and as a consequence are poorly understood. Recent investigations have established that for the most part victual mummies are joints of meat or poultry prepared as if for eating, which are wrapped, encoffined, and placed in the tomb (1,4,5). SEM has shown that salt and natron were used for desiccation (1, 5). The question that remains is whether organic balms were applied? The presence of dark residues is consistent with the appearance of balms applied to human and animal mummies (6-12). The Cairo Museum and British Museum graciously provided us with samples of tissues and balms from several meat mummies (Table 1), allowing us to assess their chemical compositions and make comparisons with...
