One example was literati painters' use of a seal, often inscribed with their byname or motto. While the tiny square of scarlet red formed a delectable contrast with the inky brushworks, it also helped the painter to announce himself, and the buyers to recognize his painting.

Reflecting on the fact that Chinese painting history over the past millennium has largely been the history of literati painting, Yang says this was more or less inevitable.

"It's not unlike today: While painter-artisans make up the bulk of the group, it is only a handful of masters whom history will eventually remember. In the case of literati painters, they were the ones who wrote the history."

James Cahill, internationally renowned Chinese art historian and collector, once wrote that Chinese painters, by inscribing and stamping their works, knowingly added a "self" onto the painting and therefore avoided the possibility of creating the visual illusion loved by their Western counterparts. Instead of being led directly into another world, the viewers are constantly reminded of the painter's presence.

Commenting on this phenomenon, Yang says: "The literati painters, steeped in ancient Chinese philosophy, believed in the unity of man and nature. They found a place for themselves in their paintings of mountains and rivers because that's where they thought they belonged."
