What is the Seal Script Style (Zhuan Shu / 篆書) in Chinese Calligraphy?
The Seal Script (篆書/Zhuan Shu/Chuan Shu) is the most archaic script of Chinese. Although this type of archaic writing can be subsumed under the general heading of Seal Script, it is in fact many numerous sub-scripts that were each used for different historical purposes. The oldest of these is the Jia Gu Wen (甲骨文/Chia Ku Wen), which was invented and used in the Shang Dynasty for prognostication ritual. This Script, although it is the oldest recorded coherent Chinese writing system, was not discovered in an archaeological context until the beginning of the last century. As a result, it has not had a large impact on the received Calligraphy tradition. Jin Wen (金文/Chin Wen), or Bronze Script, is far more well-known. This is the script that was used for inscribing ceremonial Bronze vessels in the Zhou Dynasty. The development of this script occurred in concert with Shi Gu Wen (石鼓文/Shih Ku Wen), the Stone and Drum Script. Shi Gu Wen was used for monumental stone inscriptions, and both it and Jin Wen were never standardized; the Zhou scribes were much more reliant on local custom and had to create new characters as they had need of them. Jin Wen and Shi Gu Wen are often simply called Da Zhuan (大篆/Da Chuan), or Large Seal Script.
