The sources and nature of this and the remaining "Annals"
Concerning the authorship and sources of this and the remaining
chapters in the "Annals," there is little to be said. These chapters have
the same characteristics as the preceding chapter—they are a chronological
summary listing the important events of the reign, summarizing
briefly the history to be found elsewhere in this voluminous work. The
sources used by Pan Ku seem also to be the same as for the previous
chapter, with the difference that Szu-ma Ch'ien died some time about
the end of Emperor Wu's reign or the beginning of Emperor Chao's
reign, so that the SC was not available as a source for this chapter, except
for the supplementary accounts that had later been introduced into its
text.
