Bird-worm seal script

The Chinese character 鸟 (鳥 in traditional Chinese; Niǎo in Pinyin) means "bird". The Chinese character 虫 (蟲 in traditional Chinese; Chóng in Pinyin) literally means "insect", but by extension can mean any creature that looks like a "worm", including invertebrate worms and reptiles such as snakes and lizards (and even the Chinese dragon). The character 篆 means "seal (script)".

Other names for this kind of seal script:

• Niao-Chong Script (simplified Chinese: 鸟虫书; traditional Chinese: 鳥蟲書; pinyin: Niǎo Chóng Shū). The Chinese character 书 (書 in traditional Chinese; Shū in Pinyin) here means "script".
• Niao-Chong Characters (simplified Chinese: 鸟虫文; traditional Chinese: 鳥蟲文; pinyin: Niǎo Chóng Wén). The Chinese character 文 (Wén in Pinyin) here means "character".

There are two subcategories (sub-styles):

• Bird seal script (simplified Chinese: 鸟篆; traditional Chinese: 鳥篆; pinyin: Niǎo Zhuàn. Or, simplified Chinese: 鸟书; traditional Chinese: 鳥書; pinyin: Niǎo Shū[1])
  • In this style, some parts of characters have a bird-like head and tail added. The bird style sign is a combination of two parts: a complete seal script character and one (sometimes two) bird shape(s).
• Worm seal script (simplified Chinese: 虫篆; traditional Chinese: 蟲篆; pinyin: Chóng Zhuàn. Or, simplified Chinese: 虫书; traditional Chinese: 蟲書; pinyin: Chóng Shū)
  • In this style, some or all the strokes are winding, thus producing a worm-like character, but there is no additional bird shape.

Seal script evolved from oracle bone script, and diverged into different forms in the Spring and Autumn period, after the power of the Zhou dynasty waned and China began to divide into different states.

This kind of seal script first appeared in the middle era of the Spring and Autumn period. It then became popular during the late Spring and Autumn period, and was most popular during the Warring States period. It was often seen in southern kingdoms, such as the Wu Kingdom (roughly today's Jiangsu Province), Yue Kingdom (roughly today's Zhejiang Province), Chu Kingdom (roughly today's Hunan and Hubei provinces), Cai Kingdom, Xu Kingdom, and the Song Kingdom. Each state in China during the Warring States Period had its own variety of script.

These kinds of seal script declined after the Qin Dynasty, most likely due to the unification of writing scripts by Qin Shi Huang (unified into the small seal script), after his unification of China, although they were used during the Han Dynasty.[2]

The bird seal script is often seen on bronze and iron antiques of the Yue Kingdom (roughly today's Zhejiang Province). The script was used on bronze and iron weapons, like swords, to indicate ownership or date of completion. The characters engraved on the famous Sword of Goujian provide a fine example. A few examples of the bird seal script can be seen in or on containers and jades of that period. The bird seal script was also used occasionally in the Han Dynasty seals (mainly the jade seals), as well as a few eaves tiles and bricks.[3]

The worm seal script is more common in, and probably originated from the Wu Kingdom (now roughly Jiangsu Province) or Chu Kingdom (now roughly Hunan Province and Hubei Province). Examples can be seen on antique bronze weapons, containers, jades, and seals (mainly the bronze seals of Han Dynasty),[4] and constructional or decorative parts like tiles, etc. The characters on the famous Spear of Fuchai are a good example of this category of seal script.
