Mystery sitter in Holbein portrait could be Anne Boleyn, AI analysis finds

Researchers using AI have analyzed two Renaissance sketches by Hans Holbein from the Royal Collection, known as the Windsor sketch and the Unidentified Woman. The AI model, developed by Professor Hassan Ugail at the University of Bradford, compared the entire Holbein corpus and found that the Unidentified Woman may actually be Anne Boleyn, while the Windsor sketch—long thought to depict Boleyn—may instead show her mother, Elizabeth Howard. The study suggests the works were incorrectly inscribed in the 1700s, leading to centuries of misidentification.
