35.117

征和元年魯共王（景帝子共恭同）好治宮室。壞孔子舊宅以廣其居。聞金石絲竹之聲。乃不敢壞於壁中得所藏古文虞夏商周之書及傳論語孝經。皆科斗文字。悉以書還孔子。更以竹簡寫之。詔博士孔安國作傳。初秦末孔子襄於壁中藏其家書也（襄孔子六世孫。惠帝時為博士。安國之曾祖也。壞古話反。毀之曰壞。科斗蝦蟆子。書形似之。傳直戀反。今尚書大傳是也）。

In the first year of Zhenghe, Prince Gong of Lu (son of Emperor Jing; 'Gong' [共] is the same as 'Gong' [恭]) was fond of constructing palaces and halls. He demolished the old residence of Confucius to enlarge his dwelling. Hearing the sounds of metal, stone, silk, and bamboo [instruments], he dared not demolish it further. Within the walls, he obtained the concealed ancient script texts of Yu, Xia, Shang, and Zhou, as well as the commentaries, the *Analects*, and the *Classic of Filial Piety*, all in tadpole script. He returned all these texts to the Kong family, and they were transcribed anew onto bamboo slips. An imperial decree ordered Erudite Kong Anguo to compose a commentary. Originally, at the end of the Qin, Kong Zixiang had hidden his family's books within the walls (Xiang was the sixth-generation descendant of Confucius; during the reign of Emperor Hui he served as an Erudite, and was the great-grandfather of Anguo. 'Huai' [壞] is the fanqie of gu and hua; destroying something is called *huai*. 'Tadpole' [科斗] refers to toad younglings; the shape of the calligraphy resembled them. 'Zhuan' [傳] is the fanqie of zhi and lian; what is now the *Shangshu da zhuan* is this).
