 Court painting mostly survives in what are certainly or arguably copies from much later, though the front section of the famous portrait of the Emperor Xuanzong's horse "Night-Shining White" is probably an original by Han Kan of 740-760.The Tang dynasty saw the maturity of the landscape painting tradition known as "shanshui" (mountain-water) painting, which became the most prestigious type of Chinese painting, especially when practiced by amateur scholar-official or "literati" painters in ink-wash painting.In these landscapes, usually monochromatic and sparse, the purpose was not to reproduce exactly the appearance of nature but rather to grasp an emotion or atmosphere so as to catch the "rhythm" of nature.
