Science unveils new secrets of Egyptian mummies: scanning material that composes the burial cases and masks, researchers discover insights into everyday life in ancient Egypt. From the article:

The technology is giving historians a new insight into everyday life in ancient Egypt.

The hieroglyphics found on the walls of the tombs of the Pharaohs show how the rich and powerful wanted to be portrayed. It was the propaganda of its time.

The new technique gives Egyptologists access to the real story of Ancient Egypt, according to Prof Adam Gibson of University College London, who led the project.

“Because the waste papyrus was used to make prestige objects, they have been preserved for 2,000 years,” he said. “And so these masks constitute one of the best libraries we have of waste papyrus that would otherwise have been thrown away so it includes information about these individual people about their everyday lives”

The scraps of papyrus are more than 2,000 years old. The writing on them is often obscured by the paste and plaster that holds the mummy cases together. But researchers can see what is underneath by scanning them with different kinds of light which makes the inks glow.
