c. 1300–1050 BCE (Late Shang)

Bronze Inscriptions
c. 1200–221 BCE (Shang–Zhou; continues into the Warring States)
Inscriptions cast or engraved on ritual bronzes, especially prominent from the Western Zhou onward; a major source for early political, ritual, and social history.Wikipedia ->
Chu Script

A regional script tradition used in the state of Chu, best known from brush-written bamboo and silk manuscripts with distinctive local forms.Wikipedia ->
Clerical Script
c. 300 BCE–220 CE (emerged late Warring States/Qin; dominant Han)
A practical script that evolved from late Warring States/Qin writing; it matured and became dominant in the Han dynasty, favoring faster, more rectilinear strokes.Wikipedia ->
Transmitted Pre-Qin Forms
Pre-Qin forms (≤221 BCE) / late 2nd century BCE onward (Han → later textual transmission)
Pre-Qin character forms preserved through later textual transmission (often discussed as the 'Old Text' / guwen tradition). Shaped by repeated copying, they can diverge from excavated Warring States materials.Wikipedia ->
Liushutong Seal Forms
Pre-Qin to Han seal-type forms (≤220 CE) / compiled 1661 (Min Qiji); collated and printed 1720 (Bi Hongshu)
A ten-volume compendium of seal-script variants arranged by the rhymes of Hongwu Zhengyun: each head character gives its Shuowen small seal form, then variants gathered from guwen, zhouwen, bronze inscriptions and Qin–Han seals. Long a standard reference for seal carvers, but the forms are compiled rather than excavated and were collected with little vetting, so many are of doubtful authenticity.Wikimedia Commons ->
