The weird habit of licking the end of a paintbrush has revealed new evidence about the life of an artist more than 900 years after her death. Scientists found tiny blue paint flecks had accumulated on the teeth of a medieval German nun.
The particles of the rare lapis lazuli pigment likely collected as she touched the end of her brush with her tongue. The researchers say it shows women were more involved in the illumination of sacred texts than previously thought...
According to radiocarbon dating, the woman had lived between 997 and 1162AD and was between 45-60 years old when she died. According to the authors, the woman was average in almost every aspect - except for what was stuck to her teeth.
