A team of Egyptian and German archaeologists has discovered a mummification workshop that contained a rare gilded death mask, announced Saturday.

The mask, which is more than 2,000 years old, is formed of silver with a thin layer of gold and appears to have been made for a priest of the Sufi period, said Ramadan Badry Hussein, the leader of the expedition.

“The finding of this mask could be called a sensation,” Hussein, a professor at the University of Tubingen in Germany, said at a press conference. “Very few masks of precious metals have been preserved to the present day, because the tombs of most ancient Egyptian dignitaries were looted in ancient times.”

The mummification workshop, found at the Saqqara necropolis of Memphis, is alongside a shaft that was used as a communal burial place. The last time this site was excavated was in 1900.

Some of the artifacts from the site will be put on display in the Grand Egyptian Museum, which is under construction.

The mummification workshop includes an embalmer’s cachette containing pottery vessels, bowls and measuring cups. Archaeologists are hoping to learn more about the oils used in the mummification process.

“We are in front of a gold mine of information about the chemical composition of these oils,” Hussein said.
