She added that Christians were not the only ones to use the names of angelic powers in ancient days. "Jews of antiquity were fascinated by the identity and nature of angels," she said.
Villanova University biology professor Michael Zimmerman, who also has used advanced technologies to study Egyptian mummies, said this kind of find has been sought for years.
"I did participate in an expedition to the Dakhleh Oasis in Egypt's western desert several years ago," he told FoxNews.com. "This was an early Christian site (around 200 AD), and the deceased were still being mummified, by simply being dried in the very hot climate.
"We did not see any tattoos on those mummies, so the British Museum find is remarkable."
The museum, which is located in London, will reveal what it has learned about this and seven other mummies in "Ancient Lives: New Discoveries," an exhibition scheduled to run from May 22 to Nov. 30.
John Taylor, lead curator of the ancient Egypt and Sudan department at the museum, told a local newspaper over the weekend that the exhibition will tell the story of the lives of eight people from antiquity, portraying them as full human beings, rather than as archeological objects.
