NEW WILMINGTON, Pa. - Pesed has called a Western Pennsylvania college home for about 120 years, but her caretakers don't know what she looks like.

But that might change now that researchers have a CT scan of the 2,300-year-old Egyptian mummy. Officials believe the scan will allow a forensic artist to construct a bust of Pesed, a mummy from the Nile River town of Akhmim.

Pesed has been the property of Westminster College since the Rev. John Griffin, an Egyptian missionary and a Westminster alumnus, gave the mummy to the school in 1885.

The mummy's presence at the college has allowed researchers to learn more about ancient Egyptians' diet, burial rituals and dental care.

Last week, Pesed was taken to College Fields MRI in Neshannock, Lawrence County, for a CT scan, during which computers produced images of half-millimeter-thick slices of her entire body.

The 2,500 images will allow Philadelphia forensic artist Frank Bender to sculpt the bust, a process that could take weeks.

Researchers have already pieced together some biographical details about the woman, who was mummified between 300 and 220 B.C.

CT scans and X-rays conducted in August 2001 revealed that Pesed was a 55- to 65-year-old woman who had osteoporosis at the time of her death. They also revealed abscesses along her jaw, which could indicate that she had an infection that could have led to malnutrition or death.
