At the end of the painting licking the strange habit of the artist's life has revealed more than 900 years of experience in his life.
Scientists have found that blue blue folds appear to be stacked in the teeth of a German-German.
The strange pigment of strange pencil lazuli touched on long feathers while touching his brush.
The researchers say that women are thinking of taking part in the lighting of the deeper texts.
Beginning early in the Middle Ages began researching health and diets. In a medieval monastery of Dalheim, the bones of the grave were studied.
Scientists have studied a blood calculus, especially the dental plaque, which is fossilized in your teeth during your life.
After studying the teeth of a subject, the B78, in short, revealed much more than he was eating.
According to the date of the radio, she lived between 997 and 1162AD and died at age 45-60. The authors say, the average woman had almost every aspect except her teeth narrowed down.
When researchers disassembled the samples of dental calculations, they could not believe their eyes. Hundreds of small blue particles will be visible.
"Dental calculation is very cool, while only part of your body is fossilized," said Dr. Christina Warriner, from the Max Planck Institute of the Humanities Science Institute, told BBC News.
"Throughout this process, your wastes contain all sorts of debris, so some food pieces are trapped, a little bit of life capsule."
"We found granules and pollen, but we saw that it was bright and bright blue, not just a little or a bit of minerals, but hundreds. I never saw that."
He took on important scientists to find out about the particles.
In the end, scientists realized that lapis lazuli, a rare and valuable pigment, came from an Afghan mountain.
The pencils would become dusty and would be mixed in the ultramarine: bright blue, expensive, artists like Michelangelo could not afford.
It was only used to decorate the most valuable religious manuscript in the Middle Ages.
So how did this artistic material come about in the teeth of a German German religious community?
"Based on the distribution of pigmentation in the mouth, we conclude that the probability was that he paint himself with pigment and paint his hair at the end of the painting," says Monica Tromp, commercial writer. Max Planck Institute in Jena.
According to researchers, high-level teachers and painters used a highly prized pigment.
The discovery indicates that women have been writing paper and illustrations on paper more than before.
At the time of the women's monastery, it was believed that less than 1% of the book was XII. It could have been ejected before the age.
Often, women did not name the book as a sign of humility, but the author also seemed to have a strong male marriages at that time, and the woman became invisible. According to the authors, the findings help to establish the findings directly.
"I lived in Dalheim, you can still see the faces of the women's community, but there is no art, no books, just a part of the comb, they are just a few references to the texts," said Dr. Warriner.
"He came out of history, but now we find another place where women are not thinking of artistic production."
The researchers want to develop the technique, since they have believed in many other artists who have worked with mineral pigments since then.
"I think this would be a unique opportunity to give these people identity, we have lost all of them separately."
The scientific advances in the journal have been published in the journal.
