place, but the emphasis is on individual plant forms and human and animal figures rather than the overall landscape setting. The frescos from the Tomb of Nebamun, now in the British Museum (c. 1350 BC), are a famous example. For a coherent depiction of a whole landscape, some rough system of perspective, or scaling for distance, is needed, and this seems from literary evidence to have first been developed in Ancient Greece in the Hellenistic period, although no large-scale examples survive. More ancient Roman landscapes survive, from the 1st century BCE onwards, especially frescos of landscapes decorating rooms that have been preserved at archaeological sites of Pompeii, Herculaneum and elsewhere, and mosaics. The Chinese ink painting tradition of shan shui ("mountain-water"), or "pure" landscape, in which the only sign of human life is usually a sage, or a glimpse of his hut, uses sophisticated landscape backgrounds to figure subjects, and landscape art of this period retains a classic and much-imitated status within the Chinese tradition. Both the Roman and Chinese traditions typically show grand panoramas of imaginary landscapes, generally backed with a range of spectacular mountains – in China often with waterfalls and in Rome often including sea, lakes or rivers. These were frequently used, as in the example illustrated, to bridge the gap between a foreground scene with figures and a distant panoramic vista, a persistent problem for landscape artists. The Chinese style generally showed only a distant view, or used dead ground or mist to avoid that difficulty. A major contrast between landscape painting in the West and East Asia has been that while in the West until the 19th century it occupied a low position in the accepted hierarchy of genres, in East Asia the classic Chinese mountain-water ink painting was traditionally the most prestigious form of visual art. Aesthetic theories in both regions gave the highest status to the works seen to require the most imagination from the artist. In the West this was history painting, but in East Asia it was the imaginary landscape, where famous practitioners were, at least in theory, amateur literati, including several Emperors of both China and Japan. They were often also poets whose lines and images illustrated each other. However, in the West, history painting came to require an extensive landscape background where appropriate, so the theory did not entirely work against the development of landscape painting – for several
