Western Zhou Western Zhou dynasty characters (as exemplified by bronze inscriptions of that time) basically continue from the Shang writing system; that is, early W. Zhou forms resemble Shang bronze forms (both such as clan names, and typical writing), without any clear or sudden distinction. They are, like their Shang predecessors in all media, often irregular in shape and size, and the structures and details often vary from one piece of writing to the next, and even within the same piece. Although most are not pictographs in function, the early Western Zhou bronze inscriptions have been described as more pictographic in flavor than those of subsequent periods. During the Western Zhou, many graphs begin to show signs of simplification and linearization (the changing of rounded elements into squared ones, solid elements into short line segments, and thick, variable-width lines into thin ones of uniform width), with the result being a decrease in pictographic quality, as depicted in the chart below. Some flexibility in orientation of graphs (rotation and reversibility) continues in the Western Zhou, but this becomes increasingly scarce throughout the Zhou dynasty. The graphs start to become slightly more uniform in structure, size and arrangement by the time of the third Zhou sovereign,
King Kāng, and after the ninth,
King Yì, this trend becomes more obvious. Some have used the problematic term "
large seal" (大篆
dàzhuàn) to refer to the script of this period. This term dates back to the
Han dynasty, when (small)
seal script and
clerical script were both in use. It thus became necessary to distinguish between the two, as well as any earlier script forms which were still accessible in the form of books and inscriptions, so the terms "
large seal" (大篆
dàzhuàn) and "small seal" (小篆
xiǎozhuàn, aka 秦篆
Qín zhuàn) came into being. However, since the term "large seal" is
variously used to describe
zhòuwén (籀文) examples from the ca. 800 BC
Shizhoupian compendium,
or inscriptions on both late W. Zhou bronze inscriptions and the
Stone Drums of Qin,
or all forms (including
oracle bone script) predating small seal, the term is best avoided entirely.
Eastern Zhou Spring and Autumn By the beginning of the
Eastern Zhou, in the
Spring and Autumn period, many graphs are fully linearized, as seen in the chart above; additionally, curved lines are straightened, and disconnected lines are often connected, with the result of greater convenience in writing, but a marked decrease in pictographic quality. with the forms in the
state of Qin remaining more conservative. At this time,
seals and minted coins, both probably primarily of bronze, were already in use, according to traditional documents, but none of the extant seals have yet been indisputably dated to that period. By the mid to late Spring and Autumn period, artistic derivative scripts with vertically elongated forms appeared on bronzes, especially in the eastern and southern states, and remained in use into the Warring States period (see detail of inscription from the Warring States
Tomb of Marquis Yĭ of Zēng below left). In the same areas, in the late Spring and Autumn to early
Warring States, scripts which embellished basic structures with decorative forms such as birds or worms also appeared. These are known as Bird Script (
niǎoshū 鳥書) and Worm Script (
chóngshū 蟲書), and collectively as
Bird-worm scripts, (
niǎochóngshū 鳥蟲書; see Bronze sword of King Gōujiàn to right); however, these were primarily decorative forms for inscriptions on bronzes and other items, and not scripts in daily use. Some bronzes of the period were incised in a rough, casual manner, with graph structures often differing somewhat from typical ones. It is thought that these reflected the popular (vulgar) writing of the time which coexisted with the formal script.
Warring States period Seals have been found from the
Warring States period, mostly cast in bronze, and minted bronze coins from this period are also numerous. These form an additional, valuable resource for the study of Chinese bronze inscriptions. It is also from this period that the first surviving bamboo and silk manuscripts have been uncovered. In the early Warring States period, typical bronze inscriptions were similar in content and length to those in the late
Western Zhou to
Spring and Autumn period. One of the most famous sets of bronzes ever discovered dates to the early Warring States: a large set of
biānzhōng bells from the
tomb of Marquis Yĭ of the state of Zēng, unearthed in 1978. The total length of the inscriptions on this set was almost 2,800 characters. Many, especially on weapons, recorded only the date, maker and so on, in contrast with earlier narrative contents. Beginning at this time, such inscriptions were typically engraved onto the already cast bronzes, rather than being written into the wet clay of piece-molds as had been the earlier practice. The engraving was often roughly and hastily executed. In Warring States period bronze inscriptions, trends from the late Spring and Autumn period continue, such as the use of artistically embellished scripts (e.g., Bird and Insect Scripts) on decorated bronze items. In daily writing, which was not embellished in this manner, the typical script continued evolving in different directions in various regions, and this divergence was accelerated by both a lack of central political control as well as the spread of writing outside of the nobility. In the state of Qin, which was somewhat culturally isolated from the other states, and which was positioned on the old Zhou homeland, the script became more uniform and stylistically symmetrical, rather than changing much structurally. Change in the script was slow, so it remained more similar to the typical late Western Zhou script as found on bronzes of that period and the
Shizhoupian compendium of ca. 800 BC. As a result, it was not until around the middle of the
Warring States period that popular (aka common or vulgar) writing gained momentum in Qin, and even then, the vulgar forms remained somewhat similar to traditional forms, changing primarily in terms of becoming more rectilinear. Traditional forms in Qin remained in use as well, so that two forms of writing coexisted. The traditional forms in Qin evolved slowly during the
Eastern Zhou, gradually becoming what is now called (small)
seal script during that period, without any clear dividing line (it is not the case, as is commonly believed, that small seal script was a sudden invention by
Li Si in the
Qin dynasty). Meanwhile, the Qin vulgar writing evolved into early clerical (or proto-clerical) in the late Warring States to Qin dynasty period, which would then evolve further into the
clerical script used in the
Han through the
Wei-
Jin periods. Meanwhile, in the eastern states, vulgar forms had become popular sooner; they also differed more radically from and more completely displaced the traditional forms. These eastern scripts, which also varied somewhat by state or region, were later misunderstood by
Xu Shen, author of the Han dynasty etymological dictionary
Shuowen Jiezi, who thought they predated the Warring States Qin forms, and thus labeled them
gǔwén (古文), or "ancient script". ==Computer encoding==
