《水经注·卷二十五》
自从秦始皇焚烧《诗经》、《尚书》后，经典散失残缺，汉武帝时，鲁恭王拆毁孔子旧宅，获得《尚书》、《春秋》、《论语》、《孝经》等书。当时人们已不知道还有古文，称为蟒鲜书。汉时把它秘藏起来，很少有人见过这种文字。
自秦烧《诗》、《书》，经典沦缺。汉武帝时，鲁恭王坏孔子旧宅，得《尚书》、《春秋》、《论语》、《孝经》，时人已不复知有古文，谓之科斗书，汉世秘之，希有见者。
After the First Emperor of Qin burned the "Book of Poetry" and "Book of History", the classics were lost and incomplete. During the reign of Emperor Wu of the Han Dynasty, King Gong of Lu demolished the old residence of Confucius and obtained books such as "Book of History", "Spring and Autumn Annals", "Analects of Confucius", and "The Classic of Filial Piety". At that time, people no longer knew the existence of ancient prose, and it was called Mangxian Book. It was kept secret in the Han Dynasty, and few people had ever seen this kind of text.
