Scientists have found something unusual that is to say a blue tartar was found on the teeth of a medieval skeleton. Approximately 1,000 years ago, a woman in Germany died and was buried in an unmarked grave in a church cemetery. There is no some information from her death. But when modern archeologists examined her dug-up remains, they discovered something strange; brilliant blue tartar on her teeth.
The blue particles, it turns out, were lapis lazuli, a semi-precious stone that was highly prized at the time for its vivid color and was ground up and used as a pigment.
“It’s kind of a bombshell for my field — it’s so rare to find material evidence of women’s artistic and literary work in the Middle Ages,” said Alison Beach, a professor of medieval history at Ohio State University. “Because things are much better documented for men, it’s encouraged people to imagine a male world. This helps us correct that bias. This tooth opens a window on what activities women also were engaged in.”
The unexpected discovery, described in the journal Science Advances, astonished scientists who weren’t setting out to study female artists in the Middle Ages.
“Basically all that remains are the stone foundations. A broken comb was found, but almost nothing else,” Warinner says. “There are no books that survived. There’s no art that survives. It’s known only from a handful of scraps of text that mention it in passing.”
She and a colleague were examining the teeth of skeletons from this community’s cemetery to see what had been preserved in the dental calculus, or tartar. Tartar forms from sticky plaque that traps remnants of food, bacteria and even pollen and then hardens over time. Below you may see the picture!
“It’s really an extraordinary material,” Warinner says. “It’s actually the only part of your body that fossilizes while you’re still alive.”
