The South Downs may be said to have three main component parts: the East Hampshire Downs, the Western Downs and the Eastern Downs, together with the river valleys that cut across them and the land immediately below them, the scarpfoot. The Western and Eastern Downs are often collectively referred to as the Sussex Downs. The Western Downs, lying west of the River Arun, are much more wooded, particularly on the scarp face, than the Eastern Downs. The bare Eastern Downs - the only part of the chalk escarpment to which, until the late 19th century, the term South Downs was usually applied - have come to epitomise, in literature and art, the South Downs as a whole and which have been the subject matter of such celebrated writers and artists as Rudyard Kipling (the blunt, bow-headed, whale-backed downs) and Eric Ravilious.
