In the 1500s, Renaissance art in Germany became more common as, according to Gardner, "The art of northern Europe during the sixteenth century is characterized by a sudden awareness of the advances made by the Italian Renaissance and by a desire to assimilate this new style as rapidly as possible." One of the best known practitioners of German Renaissance art was Albrecht Dürer (1471–1528), whose fascination with classical ideas led him to Italy to study art. Both Gardner and Russell recognized the importance of Dürer's contribution to German art in bringing Italian Renaissance styles and ideas to Germany. Russell calls this "Opening the Gothic windows of German art," while Gardner calls it Dürer's "life mission." Importantly, as Gardner points out, Dürer "was the first northern artist who fully understood the basic aims of the southern Renaissance," although his style did not always reflect that. The same source says that Hans Holbein the Younger (1497–1543) successfully assimilated Italian ideas while also keeping "northern traditions of close realism." This is contrasted with Dürer's tendency to work in "his own native German style" instead of combining German and Italian styles. Other important artists of the German Renaissance were Matthias Grünewald, Albrecht Altdorfer and Lucas Cranach the Elder.
