How many landscapes largely set the course for the graphic treatment of landscape until the end of the 19th century ?
The period around the end of the 15th century saw pure landscape drawings and watercolours from Leonardo da Vinci , Albrecht Dürer , Fra Bartolomeo and others , but pure landscape subjects in painting and printmaking , still small , were first produced by Albrecht Altdorfer and others of the German Danube School in the early 16th century .
