For the Chinese, the landscape is thought of as a visible key to an invisible reality. As a result, landscape painting is one of the most prized traditions in Chinese culture, one that dates back to the third century and continues to inspire Chinese artists today. Landscape painting also excites collectors, which is why several of the 42 galleries participating in Asia Week New York this year, which runs from March 13 through March 21, will be showing standout examples both ancient and contemporary.
