Yang Xi
Although no autograph copies of Yang Xi's famous calligraphy have survived, one well-documented stone rubbing version of the revealed "Huangting jing" (黃庭經, Yellow Court Scripture) has been given special attention. The Song dynasty connoisseur and critic Mi Fu (1051-1107) analyzed four manuscripts of the "Huangting jing", and said the best one was written on a silk scroll with a provenance that he traced back to the early 8th century. Mi disagreed with a former owner Tao Gu (陶穀, 903-970) who said that Wang Xizhi wrote the manuscript, and concluded it was a superb example of calligraphy from the Six Dynasties period. The Ming dynasty calligrapher and painter Dong Qichang (1555-1636) was so impressed by the Mi Fu manuscript that he made a copy, recommend it as the best model for studying "kaishu" script, and included it as the first example in his classic "Xihong tang fatie" (戲鴻堂法帖, Calligraphy Compendium of the Hall of the Playful Goose). Dong's colophon attributed the calligraphy to Yang Xi himself and described it as "the traces of a holy immortal" (Ledderose 1984: 262-263, who calls Dong's attribution to Yang "extremely optimistic").
Japanese calligraphy
The Chinese roots of Japanese calligraphy go back to the twenty-eighth century BC, to a time when pictographs were inscribed on bone for religious purposes. When this writing developed into an instrument of administration for the state, the need for a uniform script was felt and Li Si, prime minister in the Chinese dynasty of Qin, standardized a script and its way of being written. He sanctioned a form of script based on squares of uniform size into which all characters could be written from eight strokes. He also devised rules of composition where horizontal strokes are written first and characters are composed starting from top to bottom, left to right. Because the symbols were inscribed with sharp instruments, the lines were originally angular and in many ways, Li Si's achievements were made obsolete by the appearance of brush and ink (see Chinese calligraphy). The ink-wet brush creates a line quite different from a sharp stylus. It affords variation in thickness and curve of line. Calligraphy retained the block form of Li Si and his eight strokes but the writer was free to create characters that emphasized aesthetically pleasing balance and form. The way a character was written gave a message of style.
