Scientists now have an explanation for the "Screaming Woman" mummy after using CT scans to perform a "virtual dissection." It turns out she may have died in agony and experienced a rare form of muscular stiffening, called a cadaveric spasm, that occurs at the moment of death.

The examination indicated that the woman was about 48 years old when she died, had lived with mild arthritis of the spine and had lost some teeth, said Cairo University radiology professor Sahar Saleem, who led the study published in the journal Frontiers in Medicine. Her body was well-preserved, being embalmed roughly 3,500 years ago during ancient Egypt's glittering New Kingdom period using costly imported ingredients such as juniper oil and frankincense resin, Saleem added. The ancient Egyptians viewed the preservation of the body after death as crucial to secure a worthy existence in the afterlife.
