Sun Tzu Skeptics cite possible historical inaccuracies and anachronisms in the text, and that the book was actually a compilation from different authors and military strategists. Attribution of the authorship of "The Art of War" varies among scholars and has included people and movements including Sun; Chu scholar Wu Zixu; an anonymous author; a school of theorists in Qi or Wu; Sun Bin; and others. Sun Bin appears to have been an actual person who was a genuine authority on military matters, and may have been the inspiration for the creation of the historical figure "Sun Tzu" through a form of euhemerism.
Sun Tzu most of the notable figures from the Spring and Autumn period. The name "Sun Wu" () does not appear in any text prior to the "Shiji", and may have been a made-up descriptive cognomen meaning "the fugitive warrior": the surname "Sun" can be glossed as the related term "fugitive" ("xùn" ), while "Wu" is the ancient Chinese virtue of "martial, valiant" ("wǔ" ), which corresponds to Sun Tzu's role as the hero's "doppelgänger" in the story of Wu Zixu. The only historical battle attributed to Sun Tzu, the Battle of Boju, has no record of him fighting in that battle.
