Landscape Artists - Techniques

Techniques

Most early landscapes are clearly imaginary, although from very early on townscape views are clearly intended to represent actual cities, with varying degrees of accuracy. Various techniques were used to simulate the randomness of natural forms in invented compositions: the medieval advice of Cennino Cennini to copy ragged crags from small rough rocks was apparently followed by both Poussin and Thomas Gainsborough, while Degas copied cloud forms from a crumpled handkerchief held up against the light. The system of Alexander Cozens used random ink blots to give the basic shape of an invented landscape, to be elaborated by the artist.

The distinctive background view across Lake Geneva to the Le Môle peak in The Miraculous Draught of Fishes by Konrad Witz (1444) is often cited as the first Western rural landscape to show a specific scene. The landscape studies by Dürer clearly represent actual scenes, which can be identified in many cases, and were at least partly made on the spot; the drawings by Fra Bartolomeo also seem clearly sketched from nature. Dürer's finished works seem generally to use invented landscapes, although the spectacular bird's-eye view in his engraving Nemesis shows an actual view in the Alps, with additional elements. Several landscapists are known to have made drawings and watercolour sketches from nature, but the evidence for early oil painting being done outside is limited. The Pre-Raphaelite Brotherhood made special efforts in this direction, but it was not until the introduction of ready-mixed oil paints in tubes in the 1870s, followed by the portable "box easel", that painting en plein air became widely practiced.

A curtain of mountains at the back of the landscape is standard in wide Roman views and even more so in Chinese landscapes. Relatively little space is given to the sky in early works in either tradition; the Chinese often used mist or clouds between mountains, and also sometimes show clouds in the sky far earlier than Western artists, who initially mainly use clouds as supports or covers for divine figures or heaven. Both panel paintings and miniatures in manuscripts usually had a patterned or gold "sky" or background above the horizon until about 1400, but frescos by Giotto and other Italian artists had long shown plain blue skies. The single surviving altarpiece from Melchior Broederlam, completed for Champmol in 1399, has a gold sky populated not only by God and angels, but also a flying bird. A coastal scene in the Turin-Milan Hours has a sky overcast with carefully observed clouds. In woodcuts a large blank space can cause the paper to sag during printing, so Dürer and other artists often include clouds or squiggles representing birds to avoid this.

The monochrome Chinese tradition has used ink on silk or paper since its inception, with a great emphasis on the individual brushstroke to define the ts'un or "wrinkles" in mountain-sides, and the other features of the landscape. Western watercolour is a more tonal medium, even with underdrawing visible.
