习凿齿 (died c. 384) covered the period from Emperor Guangwu of Han to the end of the Western Jin in 54 scrolls. Unusually for his time he treated
蜀汉, not Wei, as the rightful heir of the Han, a view later taken up by
朱熹 and by the novel
三国演义. The book itself was lost and survives in quotations, above all in the notes to the
三国志.
