《搜神记·卷十三》
到魏明帝即位，下诏书给三公说： 谢世的父皇过去写的《典论》，都是不朽的格言。它被刻在太庙门外及太学的石碑上，和石经并列，以便永远昭示后代。 
及明帝立，诏三公曰： 先帝昔着典论，不朽之格言，其刊石于庙门之外及太学，与 石经 并以永示来世。 
When Emperor Ming of Wei took the throne, he issued an edict to the Three Dukes saying: My late father's " 典论" (Discourse on Literature) was filled with undying maxims. It was carved into stone tablets outside the Grand Temple and set up alongside the Stone Classics in the Imperial Academy, so that it would be passed down to future generations forever.
