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 ->
Qin Script
c. 475–206 BCE (Qin, Warring States → Qin dynasty)
Qin-area character forms attested on bamboo/wood slips (e.g., Shuihudi, deposited 217 BCE), overlapping chronologically with the standardization of seal script and the emergence of clerical tendencies.Wikipedia ->
Small Seal Script
Standardized 221–206 BCE (Qin); developed earlier in Qin
The standardized seal script promulgated after Qin’s unification, based on earlier Qin seal forms and used as an empire-wide norm.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 ->
