At first whiff, it sounds repulsive: sniff the essence of an ancient corpse. But researchers who indulged their curiosity in the name of science found that well-preserved Egyptian mummies actually smell pretty good.

Even around 5,000 years after their embalming, Strlič and collaborators described the bodies as smelling “pleasant.” This is largely thanks to the materials applied to the mummies, which included scented waxes, coniferous resins and oils made from pine, cedar, and juniper, as well as gum resins such as frankincense and myrrh.

The research team explained that smell was a key consideration for the ancient Egyptians during the mummification process, as pleasant odors were associated with the bodies of deities and their purity, while foul odors were considered indications of a body’s corruption and decay.
