my favourite painting, it is by Hans Holbein the younger

Hans Holbein the Younger (c. 1497 – between 7 October and 29 November 1543) was a German artist and printmaker who worked in a Northern Renaissance style. He is best known as one of the greatest portraitists of the 16th century. He also produced religious art, satire, and Reformation propaganda, and made a significant contribution to the history of book design. He is called "the Younger" to distinguish him from his father, Hans Holbein the Elder, an accomplished painter of the Late Gothic school.

Born in Augsburg, Holbein worked mainly in Basel as a young artist. At first he painted murals and religious works and designed for stained glass windows and printed books. He also painted the occasional portrait, making his international mark with portraits of the humanist Desiderius Erasmus of Rotterdam. When the Reformation reached Basel, Holbein worked for reformist clients while continuing to serve traditional religious patrons. His Late Gothic style was enriched by artistic trends in Italy, France, and the Netherlands, as well as by Renaissance Humanism. The result was a combined aesthetic uniquely his own.

Holbein travelled to England in 1526 in search of work, with a recommendation from Erasmus. He was welcomed into the humanist circle of Thomas More, where he quickly built a high reputation. After returning to Basel for four years, he resumed his career in England in 1532. This time he worked for the twin founts of patronage, Anne Boleyn and Thomas Cromwell. By 1535, he was King's Painter to King Henry VIII. In this role, he produced not only portraits and festive decorations but designs for jewellery, plate, and other precious objects. His portraits of the royal family and nobles are a record of the court in the years when Henry was asserting his supremacy over the English church.
