蘇軾

金陵艾宣畫翎毛花竹，為近歲之冠。既老，筆跡尤奇，雖不復精勻，而氣格不凡。今尚在，然眼昏不能複運筆矣。

Su Shi, also known as Su Dongbo, was not only a great poet of the Song dynasty, but he also became a revered calligrapher, painter and theoretician. His comments about painting helped form the basis of what is called "literati painting" or "Southern School" of painting. 

Commentary on paintings became a literary genre, and here Su writes about his near contemporary Ai Xuan's animal and flower paintings, praising him as the "crown of his day."
