Buried with a padlock on her foot and an iron sickle across her neck, "Zosia" was never supposed to be able to come back from the dead.
Entombed in an unmarked cemetery in Pien, northern Poland, the young woman was one of dozens feared by her neighbors to have been a "vampire".
Now, using DNA, 3D printing and modelling clay, a team of scientists has reconstructed Zosia's 400-year-old face, revealing the human story buried by supernatural beliefs, Reuters reported.
"It's really ironic, in a way," said Swedish archaeologist Oscar Nilsson. "These people burying her, they did everything they could in order to prevent her from coming back from the dead... we have done everything we can in order to bring her back to life."
Zosia, as she was named by locals, was found in 2022 by a team of archaeologists from Torun's Nicolaus Copernicus University.
Aged 18-20 when she died, analysis of Zosia's skull suggests she suffered from a health condition which would have caused fainting and severe headaches, as well as possible mental health issues, Nilsson said.
The sickle, the padlock and certain types of wood found at the grave site were all believed at the time to hold magical properties protecting against vampires, according to the Nicolaus Copernicus team.
Zosia's was Grave No. 75 at the unmarked cemetery in Pien, outside the northern city of Bydgoszcz. Among the other bodies found at the site was a "vampire" child, buried face down and similarly padlocked at the foot.
Little is known of Zosia's life, but Nilsson and the Pien team say items she was buried with point to her being from a wealthy — possibly noble — family.
The 17th century Europe she lived in was ravaged by war, something Nilsson suggests created a climate of fear in which belief in supernatural monsters was commonplace.
Nilsson's recreation began with creating a 3D printed replica of the skull, before gradually building layers of plasticine clay "muscle by muscle" to form a life-like face.
He uses bone structure combined with information on gender, age, ethnicity and approximate weight to estimate the depth of facial features.
"It's emotional to watch a face coming back from the dead, especially when you know the story about this young girl," Nilsson says.
Nilsson said he wanted to bring Zosia back "as a human, and not as this monster that she is buried as".

Scientists have discovered the oldest-known fossil of a giant tadpole that wriggled around over 160 million years ago.

The new fossil, found in Argentina, surpasses the previous ancient record holder by about 20 million years.

Imprinted in a slab of sandstone are parts of the tadpole's skull and backbone, along with impressions of its eyes and nerves.

“It's not only the oldest tadpole known, but also the most exquisitely preserved,” said study author Mariana Chuliver, a biologist at Buenos Aires’ Maimonides University.

Researchers know frogs were hopping around as far back as 217 million years ago. But exactly how and when they evolved to begin as tadpoles remains unclear.

This new discovery adds some clarity to that timeline. At about a half foot (16 centimeters) long, the tadpole is a younger version of an extinct giant frog.

“It's starting to help narrow the timeframe in which a frog becomes a frog,” said Ben Kligman, a paleontologist at the Smithsonian National Museum of Natural History who was not involved with the research.

The results were published Wednesday in the journal Nature.

The fossil is strikingly similar to the tadpoles of today — even containing remnants of a gill scaffold system that modern-day tadpoles use to sift food particles from water.

That means the amphibians' survival strategy has stayed tried and true for millions of years, helping them outlast several mass extinctions, Kligman said.
