Using artificial intelligence, researchers may have identified the previously unknown subject of a sketch by Northern Renaissance artist Hans Holbein, and reidentified the sitter for a related Holbein drawing. The study, carried out by Karen L. Davies and Hassan Ugail, was published in the journal npj Heritage Science.

Holbein was born in Germany but moved to England to escape the European Reformation, initially under the patronage of Oliver Cromwell and Henry VIII’s ill-fated second wife, Anne Boleyn. He worked as a portraitist in the Tudor court starting around 1526 until his death in 1543.
