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").
Armenian alphabet
The earliest known example of the script's usage was a dedicatory inscription over the west door of the church of Saint Sarkis in Tekor. Based on the known individuals mentioned in the inscription, it has been dated to the 480s. The earliest known surviving example of usage outside of Armenia is a mid-6th century mosaic inscription in the chapel of St Polyeuctos in Jerusalem. A papyrus discovered in 1892 at Fayyum and containing Greek words written in Armenian script has been dated on historical grounds to before the Arab conquest of Egypt, i.e. before 640, and on paleographic grounds to the 6th century and perhaps even the late 5th century. It is now in the Bibliotheque Nationale de France. The earliest surviving manuscripts written in Armenian using Armenian script date from the 7th–8th century.
