The Chinese picture-scroll, a long painting or calligraphic work held within a horizontal scrolling mount, has been China's pre-eminent aesthetic format for the last two millennia. This first extended history of the picture-scroll explores its extraordinary longevity, and its adaptability to social, political and technological change. The book describes what the picture-scroll demands of a viewer, how China's artists grappled with its cultural power, and how collectors and connoisseurs have left their marks on scrolls for later generations to judge. The return to mass appeal of scrolling - a media technology that seemed long outdated yet persists in our digital age - provides urgent and fascinating context to this book.
