金文 (literally "metal writing") refers to inscriptions cast or engraved on bronze ritual vessels (
鼎,
簋) during the Shang (
商) and Zhou (
周) dynasties, c. 1300-300 BCE. Stylistically it sits between oracle-bone script (
甲骨文, jiǎgǔwén) and seal script (
篆书, zhuànshū) and is a key source for Old Chinese reconstruction.
