Handscroll

The handscroll is a long narrow scroll for displaying a series of scenes in Chinese, Japanese, or Korean painting and calligraphy. The handscroll presents an artwork in the horizontal form and can be exceptionally long, usually measuring up to a few meters in length and around 25–40 cm in height. Handscrolls are generally viewed starting from the right end. This kind of scroll is intended to be viewed flat on a table while admiring it section for section during the unrolling as if traveling through a landscape. In this way, this format allows for the depiction of a continuous narrative or journey.
