The Art of War by active 6th century B.C. Sunzi

[See _supra_, §§ 3, 4.] Such is the art of manœuvering. [With these words, the chapter would naturally come to an end. But there now follows a long appendix in the shape of an extract from an earlier book on War, now lost, but apparently extant at the time when Sun Tzŭ wrote. The style of this fragment is not noticeably different from that of Sun Tzŭ himself, but no commentator raises a doubt as to its genuineness.]
