Chinese bronze inscriptions

Chinese bronze inscriptions, also referred to as bronze script or bronzeware script, comprise Chinese writing made in several styles on ritual bronzes mainly during the Late Shang dynasty (c. 1250 – c. 1046 BC) and Western Zhou dynasty (c. 1046 – 771 BC). Types of bronzes include zhong bells and ding tripodal cauldrons. Early inscriptions were almost always made with a stylus into a clay mold, from which the bronze itself was then cast. Additional inscriptions were often later engraved onto bronzes after casting. The bronze inscriptions are one of the earliest scripts in the Chinese family of scripts, preceded by the oracle bone script.

For the early Western Zhou to early Warring States period, the bulk of writing which has been unearthed has been in the form of bronze inscriptions. As a result, it is common to refer to the variety of scripts of this period as "bronze script", even though there is no single such script. The term usually includes bronze inscriptions of the preceding Shang dynasty as well. However, there are great differences between the highly pictorial Shang emblem (aka "identificational") characters on bronzes (see "ox" clan insignia below), typical Shang bronze graphs, writing on bronzes from the middle of the Zhou dynasty, and that on late Zhou to Qin, Han and subsequent period bronzes. Furthermore, starting in the Spring and Autumn period, the writing in each region gradually evolved in different directions, such that the script styles in the Warring States of Chu, Qin and the eastern regions, for instance, were strikingly divergent. In addition, artistic scripts also emerged in the late Spring and Autumn to early Warring States, such as Bird Script (鳥書 niǎoshū), also called Bird Seal Script (niǎozhuàn 鳥篆), and Worm Script (chóngshū 蟲書).

Of the abundant Chinese ritual bronze artifacts extant today, about 12,000 have inscriptions. These have been periodically unearthed ever since their creation, and have been systematically collected and studied since at least the Song dynasty. The inscriptions tend to grow in length over time, from only one to six or so characters for the earlier Shang examples, to forty or so characters in the longest, late-Shang case, and frequently a hundred or more on Zhou bronzes, with the longest up to around 500.

In general, characters on ancient Chinese bronze inscriptions were arranged in vertical columns, written top to bottom, in a fashion thought to have been influenced by bamboo books, which are believed to have been the main medium for writing in the Shang and Zhou dynasties. The very narrow, vertical bamboo slats of these books were not suitable for writing wide characters, and so a number of graphs were rotated 90 degrees; this style then carried over to the Shang and Zhou oracle bones and bronzes. Examples:

Of the 12,000 inscribed bronzes extant today, roughly 3,000 date from the Shang dynasty, 6,000 from the Zhou dynasty, and the final 3,000 from the Qin and Han dynasties.

Inscriptions on Shang bronzes are of a fairly uniform style, making it possible to discuss a "Shang bronze script", although great differences still exist between typical characters and certain instances of clan names or emblems. Like early period oracle bone script, the structures and orientations of individual graphs varied greatly in the Shang bronze inscriptions, such that one may find a particular character written differently each time rather than in a standardized way (see the many examples of "tiger" graph to the lower left).^{[clarification needed]}

As in the oracle bone script, characters could be written facing left or right, turned 90 degrees, and sometimes even flipped vertically, generally with no change in meaning. For instance, and both represent the modern character xū 戌 (the 11th Earthly Branch), while and are both hóu 侯 "marquis". This was true of normal as well as extra complex identificational graphs, such as the hǔ 虎 "tiger" clan emblem at right, which was turned 90 degrees clockwise on its bronze.

These inscriptions are almost all cast (as opposed to engraved), and are relatively short and simple. Some were mainly to identify the name of a clan or other name, while typical inscriptions include the maker's clan name and the posthumous title of the ancestor who is commemorated by the making and use of the vessel. These inscriptions, especially those late period examples identifying a name, are typically executed in a script of highly pictographic flavor, which preserves the formal, complex Shang writing as would have primarily been written on bamboo or wood books, as opposed to the concurrent simplified, linearized and more rectilinear form of writing as seen on the oracle bones.
