Chunqiu Zuo Zhuan, the Chronicle of Zuo, is among the earliest Chinese works of narrative history, covering the period from 722 to 468 BC. It is one of the most important sources for understanding the history of the Spring and Autumn Period. Together with the Gongyang Zhuan and Guliang Zhuan, the work forms one of the surviving Three Commentaries on the Spring and Autumn Annals. This volume includes both the orginal text from the annals and the complete commentary.
