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
Though less than a century intervenes between the Ravenna cursive and the oldest extant Merovingian document (AD 625), there is a great difference in appearance between the two writings. The facile flow of the former is replaced by a cramped style, in which the natural slope to the right gives way to an upright hand, and the letters, instead of being fully outlined, are compressed to such an extent that they modify the shape of other letters. Copyists of books used a cursive similar to that found in documents, except that the strokes are thicker, the forms more regular, and the heads and tails shorter. The Merovingian cursive as used in books underwent simplification in some localities, undoubtedly through the influence of the minuscule book-hand of the period. The two principal centres of this reform were Luxeuil and Corbie.In Spain, after the Visigothic conquest, the Roman cursive gradually developed special characteristics. Some documents attributed to the 7th century display a transitional hand with straggling and rather uncouth forms. The distinctive features of Visigothic writing, the most noticeable of which is certainly the q-shaped g, did not appear until later, in the book-hand. The book-hand became set at an early date. In the 8th century it appears as a sort of semi-cursive; the earliest example of certain date is ms lxxxix in the Capitular Library in Verona. From the 9th century the calligraphic forms become broader and more rounded until the 11th century, when they become slender and angular. The Visigothic minuscule appears in a cursive form in documents about the middle of the 9th century, and in the course of time grows more intricate and consequently less legible. It soon came into competition with the Carolingian minuscule, which supplanted it as a result of the presence in Spain of French elements such as Cluniac monks and warriors engaged in the campaign against the Moors.
