According to Ban Gu, writing in the "Book of Han", the "Analects" originated as individual records kept by Confucius's disciples of conversations between the Master and them, which were then collected and jointly edited by the disciples after Confucius's death in 479 BC. The work is therefore titled "Lunyu" meaning "edited conversations" or "selected speeches" (i.e. analects). This broadly forms the traditional account of the genesis of the work accepted by later generations of scholars, for example the Song dynasty neo-Confucian scholar Zhu Xi stated that "Analects" is the records of Confucius's first- and second-generation pupils.
