At fifteen, Turner was already exhibiting View of Lambeth. He soon acquired the reputation of an immensely clever watercolourist. A disciple of Girtin and Cozens, he showed in his choice and presentation of theme a picturesque imagination which seemed to mark him out for a brilliant career as an illustrator. He travelled, first in his native land and then on several occasions in France, the Rhine Valley, Switzerland and Italy. He soon began to look beyond illustration. However, even in works in which we are tempted to see only picturesque imagination, there appears his dominant and guiding ideal of lyric landscape. His choice of a single master from the past is an eloquent witness for he studied profoundly such canvases of Claude as he could find in England, copying and imitating them with a marvellous degree of perfection.
