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").
Muratorian fragment
The Muratorian fragment, also known as the Muratorian Canon or Canon Muratori, is a copy of perhaps the oldest known list of most of the books of the New Testament. The fragment, consisting of 85 lines, is a 7th-century Latin manuscript bound in a 7th or 8th century codex from the library of Columbanus's monastery at Bobbio Abbey; it contains features suggesting it is a translation from a Greek original written about 170 or as late as the 4th century. Both the degraded condition of the manuscript and the poor Latin in which it was written have made it difficult to translate. The beginning of the fragment is missing, and it ends abruptly. The fragment consists of all that remains of a section of a list of all the works that were accepted as canonical by the churches known to its original compiler. It was discovered in the Ambrosian Library in Milan by Father Ludovico Antonio Muratori (1672–1750), the most famous Italian historian of his generation, and published in 1740.
