Ban Zhao
For the periods where they overlapped, Ban Gu adopted nearly verbatim much of Sima Qian's material, though in some cases he also expanded it. He also incorporated at least some of what his father had written, though it is difficult to know how much. The completed work ran to a total of 100 fascicles 卷, and included essays on law, science, geography, and literature. Ban Gu's younger sister Ban Zhao finished writing the book in 111, 19 years after Ban Gu had died in prison. An outstanding scholar in her own right, she is thought to have written volumes 13–20 (eight chronological tables) and 26 (treatise on astronomy), the latter with the help of Ma Xu. As with the "Records of the Grand Historian", Zhang Qian, a notable Chinese general who travelled to the west, was a key source for the cultural and socio-economic data on the Western Regions contained in the 96th fascicle. The "Annals" section and the three chapters covering the reign of Wang Mang were translated into English by Homer H. Dubs. Other chapters have been rendered into English by A. F. P. Hulsewé, Clyde B. Sargent, Nancy Lee Swann, and Burton Watson.
