He is best known as one of the greatest portraitists of the 16th century.olbein's art was prized from early in his career. The French poet and reformer Nicholas Bourbon dubbed him the Apelles of our time, a typical contemporary accolade. Holbein has also been described as a great one-off of art history, since he founded no school.
