太史公序
The Grand Historian's Preface
太史公曰:五帝、三代之記,尚矣。自殷以前諸侯不可得而譜,周以來乃頗可著。孔子因史文次春秋,紀元年,正時日月,蓋其詳哉。至於序尚書則略,無年月;或頗有,然多闕,不可錄。故疑則傳疑,蓋其慎也。
余讀諜記,黃帝以來皆有年數。稽其歷譜諜終始五德之傳,古文鹹不同,乖異。夫子之弗論次其年月,豈虛哉!於是以五帝系諜、尚書集世紀黃帝以來訖共和為世表。
The Grand Historian says: The records of the Five Emperors and the Three Dynasties stretch back into deep antiquity. Before the Yin dynasty, the lineages of the feudal lords cannot be reconstructed; only from the Zhou onward can they be set down with any confidence. Confucius used the official records to compile the Spring and Autumn Annals, noting the first years of reigns, fixing the months and days — how thorough he was! Yet when he arranged the Documents, the treatment was sparse, with no dates; or if there were some, many were missing and could not be recorded. Where matters were doubtful he transmitted the doubt — such was his caution.
I have read the genealogical registers, and from the Yellow Emperor onward all have year-counts. But when I checked the calendrical tables, genealogies, and the traditions of the cyclic succession of the Five Powers, the ancient texts all disagree and conflict with one another. That the Master refrained from arranging their chronology — was this not well founded? Accordingly, I have used the Five Emperors' genealogies and the Documents to compile a generational table from the Yellow Emperor down to the Gonghe Regency.
Notes
The Grand Historian (太史公) is Sima Qian (司馬遷, c. 145–86 BC), author of the Shiji. He inherited the office of Grand Historian from his father Sima Tan.
The Five Powers (五德) refers to the cosmological theory that dynastic succession follows a cycle of five phases (wood, fire, earth, metal, water). Each dynasty rules under one phase and is supplanted by the next in the conquest cycle. This theory was systematized by Zou Yan (鄒衍) in the late Warring States period.
The Gonghe Regency (共和, 841–828 BC) marks the beginning of reliable Chinese chronology. After King Li of Zhou was driven out, the Duke of Shao and the Duke of Zhou governed jointly. From 841 BC onward, continuous year-by-year records survive.
