The Ambassadors, Jean de Dinteville and Georges de Selve, 207x209 cm, 1533, National Gallery, London. Hans Holbein (c. 1497/98–1543) was the most important portrait painter of the German Renaissance, skilled in psychological portrayal within a delicate and superb naturalistic realism, vividly revealing the profound inner spirit of perfect humanism. His most famous work, "The Ambassadors" (Ambassdors) (1533), employs dramatic anamorphic illusion. (Anamorphosis: a painting technique where the artist deliberately paints from a specific angle; viewers must observe it from that unique vantage point to comprehend the intended content.)
