Historical novelist Nancy Bilyeau describes Hans Holbein's career at Henry VIII's Court and how he survived painting the great portrait of Thomas More (perhaps residing in More's home in Chelsea) and painting the perhaps over flattering portrait of Anne of Cleves. Holbein had some trouble finding the right patrons and portrait subjects--Anne Boleyn was a patron for a time (she lost her head) and Thomas Cromwell was another protrait subject (and he lost his head). Another fascinating story about Henry VIII's Court.
I am curious about what happened to the portrait of More after the fall and execution of Thomas More: did Margaret Roper take the painting with her to the Continent? This site includes a great analysis of the painting, which is now in the Frick Collection, New York City, NY.
By the way, this site has a portrait from the studio of Hans Holbein of More's second wife Alice.
