Ancient Funerary Mask Painted With Human Blood Found In A Macabre Burial In Peru

Sican Mask With Blood Paint

Journal of Proteome ResearchResearchers initially thought this mask’s paint was made with a relatively common pigment known as cinnabar — but new analysis has just revealed that the secret ingredient was actually human blood.

Researchers had long been mystified by the red paint found on a funerary mask taken from the skull of a Sicán elite who was buried 1,000 years ago in present-day Peru. More than anything else, experts were baffled as to how the paint had stayed so intact for a millennium.

“This is important because we have an opportunity to learn and understand from our collective history and make meaningful change,” said Rebecca Riley, a member of Albuquerque’s Commission on American Indian and Alaska Native Affairs.

“We deserve to understand the truth, determine our steps forward, and owe the Native children and staff who never returned home to do better.”
