Why a Medieval Woman Had Lapis Lazuli Hidden in Her Teeth
An analysis of dental plaque illuminates the forgotten history of female scribes.
What Anita Radini noticed under the microscope was the blue—a brilliant blue that seemed so unnatural, so out of place in the 1,000-year-old dental tartar she was gently dissolving in weak acid.
It was ultramarine, she would later learn, a pigment that a millennium ago could only have come from lapis lazuli originating in a single region of Afghanistan. This blue was once worth its weight in gold. It was used, most notably, to give the Virgin Mary’s robes their striking color in centuries of artwork. And the teeth that were embedded with likely belonged to a scribe or painter of medieval manuscripts.
