AI Helps UK Researchers Identify Unknown Subject in Hans Holbein Drawing as Anne Boleyn

Researchers Karen L. Davies and Hassan Ugail used artificial intelligence facial recognition to analyze two Hans Holbein drawings from the Royal Collection Trust. Their study, published in npj Heritage Science, suggests that a portrait previously labeled as Anne Boleyn actually depicts her mother, Elizabeth Howard, while a drawing cataloged as an unidentified woman is the true likeness of Anne Boleyn. The findings challenge long-held identifications based on 18th-century inscriptions and align more closely with contemporary descriptions of Boleyn as slender with dark hair.

scientists recreate egyptian blue pigment 2653299

A team of researchers has successfully recreated Egyptian blue, the world's oldest synthetic pigment, which was used by ancient Egyptians from as early as 3100 B.C.E. The study, published in NPJ Heritage Science, was led by John S. McCloy of Washington State University and Edward P. Vicenzi of the Smithsonian Institution's Museum Conservation Institute, in collaboration with the Carnegie Museum of Natural History. The researchers experimented with various minerals, heating them in ovens at around 1,000 degrees Celsius for up to 11 hours, and used modern microscopy and analysis techniques to compare their results with ancient artifacts from the Carnegie Museum's collection.

egyptian blue pigment recreated 1234744161

A team led by Washington State University has successfully recreated Egyptian Blue, the oldest manufactured pigment in history, which was first synthesized in ancient Egypt and used in funerary rituals and Roman art. The production process was lost during the Renaissance. Working with the Smithsonian’s Museum Conservation Institute and the Carnegie Museum of Natural History, the researchers developed 12 recipes using silicon dioxide, copper, calcium, and sodium carbonate, heating them at around 1,000 degrees Celsius for up to 11 hours to mimic ancient methods. They discovered that only half the expected amount of blue-producing compounds was needed to achieve the exact chemical match.
