Many previous thinkers have imagined that there was a glorious or harmonious period in the past better than the world of their own time, but Thucydides and Sima Qian do not describe the early stages of human society as a Golden Age. I suggest that Sima Qian marks a separation between the mythical stories and the historical spirit in China, just as Thucydides did in Greece. Further, they both presented a modified cyclical view of human history. For a better understanding of the basic characteristics of Greek and Chinese historiographies, this paper discusses the cyclical views of human history underlying ancient Greek and early Chinese historiographies through a comparative study of Thucydides’ and Sima Qian’s texts. I analyze some similarities and differences between the two great historians’ conceptions of historical process, and I conclude that Thucydides believes human intelligence develops through a historical spiral, while Sima Qian focuses on dynastic cycles with a strong moral concern.
