Ouyang led the commission compiling the
New Book of Tang, which completed its work in 1060. He wrote
New History of the Five Dynasties on his own following his official service. The book was not discovered until after his death. As a historian, he has been criticised as overly didactic, but he played an important role in establishing the use of
epigraphy as a historiographic technique. Epigraphy, as well as the practice of calligraphy, figured in Ouyang's contributions to Confucian
aesthetics. In his
Record of the Eastern Study he states how literary minded gentlemen might utilize their leisure to nourish their mental state. The practice of calligraphy and the appreciation of associated art objects were integral to this Daoist-like transformation of intellectual life. The Ming dynasty writer
Feng Menglong recorded a possibly apocryphal anecdote regarding Ouyang's writing style in his collection of short stories ''Gujin Tan'gai'' (). As the story goes, during one of Ouyang's trips outside the Hanlin Academy with his associates, they witnessed an unusual event: a horse became spooked, galloped down a busy street, and kicked to death a dog sleeping there. Ouyang challenged his two associates to express this event in writing. One wrote: "A dog was lying in the thoroughfare and was kicked to death by a galloping horse," while the other wrote: "A horse galloped down a thoroughfare. A lying dog encountered it and was killed." Ouyang teased his junior colleagues, "A history book in your hands would remain incomplete after ten thousand volumes." When asked for his own rendering, Ouyang, replying with a smile, wrote: "A galloping horse killed a dog in its path." In 1044, Ouyang wrote
On Factions, which argued that coalitions in government should not be taboo and that groups of like-minded men working for the court was constructive. ==Poetry==
