An intaglio process whereby lines are cut into a metal or wood plate using an engraving tool (a burin), which is pushed in front of the hand to achieve a sharp controlled incision capable of great delicacy. This technique requires a great deal of control and is not suited to spontaneous mark-making.

An intaglio process whereby a metal plate (normally copper, zinc or steel) is covered with an acid-resistant layer of rosin mixed with wax. With a sharp point, the artist draws through this ground to reveal the plate beneath. The plate is then placed in an acid bath (a water and acid solution) and the acid bites into the metal plate where the drawn lines have exposed it. The waxy ground is cleaned off and the plate is covered in ink and then wiped clean, so that ink is retained only in the etched lines. The plate can then be printed through an etching press. The strength of the etched lines depends on the length of time the plate is left in the acid bath.

Landscape is one of the principle genres of Western art. In early paintings the landscape was a backdrop for the composition, but in the late 17th Century the appreciation of nature for its own sake began with the French and Dutch painters (from whom the term derived). Their treatment of the landscape differed: the French tried to evoke the classical landscape of ancient Greece and Rome in a highly stylised and artificial manner; the Dutch tried to paint the surrounding fields, woods and plains in a more realistic way. As a genre, landscape grew increasing popular, and by the 19th Century had moved away from a classical rendition to a more realistic view of the natural world. Two of the greatest British landscape artists of that time were John Constable and JMW Turner, whose works can be seen in the Tate collection (www.tate.org.uk). There can be no doubt that the evolution of landscape painting played a decisive role in the development of Modernism, culminating in the work of the Impressionists and Post-Impressionists . Since then its demise has often been predicted and with the rise of abstraction, landscape painting was thought to have degenerated into an amateur pursuit. However, landscape persisted in some form into high abstraction, and has been a recurrent a theme in most of the significant tendencies of the 20th Century. Now manifest in many media, landscape no longer addresses solely the depiction of topography, but encompasses issues of social, environmental and political concern.
