Dental Examination of the Mummies
Three of the mummies in the collection have been subjected to dental examination using a panoramic X-ray unit at the Edinburgh Dental Hospital. This "Panoramic Radiograph" gives a clear detail of the jaw structure, showing details of the teeth, and also of the roots.
The first mummies to be examined were the two from Qurneh. The teeth of the adult show moderate wear. Most of the teeth are present, with only a few lost after death. Two of the teeth are slightly decayed. This would have not been uncommon in Ancient Egypt as a lot of sweet things, particularly a weak type of beer and honey formed an appreciable part of the diet.
There is visible staining on the teeth on the left hand side of the jaw. This may be due to the body lying on it's side after death. Dental evidence indicates that the woman was between 21 and 30 at death.
The child had a virtually complete set of baby teeth, with one lost after death. The indicated age at death was 2 to 3 years.
The third mummy examined, from a child found at Hawara, had more developed teeth, with the molars beginning to erupt. This indicates an age at death of 5 to 6. The teeth and jaw appear to be healthy.
Conservation Assessment of Egyptian Textiles
Textiles, particularly linen, are often found in Egyptian burials. Textiles were used as mummy wrappings, clothes, nets or bags, or sometimes as internal packing. Old or worn out household textiles such as clothing, sheets, towels and bags were frequently used to wrap or pack the mummy.
The look for obvious signs of wear to indicate the re-use of every day household textiles in the mummification process.
Conservation of a mummy
One of the mummies in the collection was already unwrapped when it was acquired by the collection in 1911. The body was resting on the underside of the cartonage case in it's coffin.
A conservation assessment in 1991 showed that the mummy itself had suffered a lot of post mortem damage and was covered in dirt. The coffin had collapsed and was in a poor condition. The base contained plaster debris and also damage from insects boring into the wood. Although the damage was extensive and the remains were fragile, the mummy itself showed a very high quality of mummification. The finger and toe prints are still visible for example.
It was initially hoped to carry out repairs on the body itself. It was discovered however that the upper and lower parts of the body were out of alignment. Any repairs would require the body to be properly aligned, and it was decided that to correct this would cause more damage to the fragile remains. After discussion it was decided not to attempt any of the proposed repairs.
The coffin was cleared of dust and dirt by careful vacuuming. This revealed the painted figure of Sokaris, the god of death and resurrection.
When the body was cleaned it was found to be coated in a thick layer of resin. Analysis showed this to be Kauri copal resin. This actually originates in New Zealand, so was obviously not original.
Once the resin was identified it was carefully removed using a solvent which did not damage the skin. This greatly improved the appearance of the mummy.
What happens next ?
The next stage is to CT scan the remaining 9 mummies in the collection. In addition further work has to be carried out to understand more fully some features observed in the two mummies which have been scanned. Once this has been done further medical examinations are planned based on the results. It is hoped to find out more about the possible Trepanation of the skull and the presence of TB in the young female.
