The Recors of the Grand Historian (traditional Chinese: 史記; simplified Chinese: 史记; pinyin: Shǐjì; Wade-Giles: Shih-chi) written from 109 BC to 91 BC, was the magnum opus of Sima Qian, in which he recounted Chinese history from the time of the Yellow Emperor until his own time. (The Yellow Emperor, traditionally dated ca. 2600 BC, is the first ruler whom Sima Qian considers sufficiently established as historical to appear in the Records.) As the first systematic Chinese historical text, the Records profoundly influenced Chinese historiography and prose. In its impact, the work is comparable to Herodotus and his Histories.
