Authorship

Since fiction was not at first a prestigious genre in the Chinese literary world, authorship of early novels was often not carefully attributed and may be unknowable. The authorship of Water Margin is still in some sense uncertain, and the text in any case derived from many sources and involved many editorial hands. While the novel was traditionally attributed to Shi Nai'an, of whose life nothing is reliably known, recent scholars think that the novel, or portions of it, may have been written or revised by Luo Guanzhong (the author of Romance of the Three Kingdoms). Other contenders include Shi Hui (施惠) and Guo Xun (郭勛).
