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").
Skara Missal
The Skara Missal is a 12th-century illuminated manuscript, a missal kept in "Stifts- och landsbiblioteket i Skara", a library in Skara, Sweden. It is the oldest surviving missal of this kind in Scandinavia. It is written in Latin, and is in folio format. Only about one eighth of the original remains, or 44 pages. The book was originally bound in a single volume, but is since the 13th or 14th century split into two volumes. One of the volumes is currently part of the permanent exhibition of Västergötland Museum. It was written by two different scribes. It contains text, illuminations and musical notes. The illuminations consist of two full page illustrations, four large decorative initials and a number of smaller ones. Certain traits indicate that the illuminator may have come from Scandinavia.
