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").
Stoichedon
The stoichedon style of epigraphy (from στοιχηδόν, a Greek adverb meaning "in a row") was the practice of engraving ancient Greek inscriptions in capitals in such a way that the letters were aligned vertically as well as horizontally. Texts of this form give the appearance of being composed in a grid with the same number of letters in each line and each space in the grid filled with a single letter; hence, there are no spaces between words, and no spaces or punctuation between sentences. The majority are Attic, but it was widely used in the Greek world, and the earliest examples are from not later than the mid-6th century BCE; the first is perhaps the Phrasikleia Kore or the Salaminian Decree. It was the dominant style of inscription in Athens during the 5th and 4th centuries BCE and was the preferred style for official state proclamations. The last stoichedon text dates from the 3rd century CE and is the genealogical inscription from the Heroon of Oenoanda in Lycia. The idiom was less common in Latin epigraphy, a rare exception is the Sator square.
