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").
Palaeography
The earliest Greek papyrus yet discovered is probably that containing the "Persae" of Timotheus, which dates from the second half of the 4th century BC and its script has a curiously archaic appearance. E, Σ, and Ω have the capital form, and apart from these test letters the general effect is one of stiffness and angularity. More striking is the hand of the earliest dated papyrus, a contract of 311 BC. Written with more ease and elegance, it shows little trace of any development towards a truly cursive style; the letters are not linked, and though the uncial c is used throughout, E and Ω have the capital forms. A similar impression is made by the few other papyri, chiefly literary, dating from about 300 BC; E may be slightly rounded, Ω approach the uncial form, and the angular Σ occurs as a letter only in the Timotheus papyrus, though it survived longer as a numeral (= 200), but the hands hardly suggest that for at least a century and a half the art of writing on papyrus had been well established. Yet before the middle of the 3rd century BC, one finds both a practised book-hand and a developed and often remarkably handsome cursive.
