《南史·列传·卷十九》
等谢混等人被杀后，谢方明、蔡廓到刘穆之那里去，刘穆之非常高兴，对武帝说： 谢方明可以说是名家驹，他和蔡廓应当安排为和三公位置等同的人，不要说还有更高的人材。 
及混等诛后，方明、廓来往造穆之，穆之大悦，白武帝曰： 谢方明可谓名家驹，及蔡廓直置并台鼎人，无论复有才用。 
After Xie Hun and others were killed, Xie Fangming and Cai Kuo went to Liu Muzhi. Liu Muzhi was very happy and said to Emperor Liu: "Xie Fangming can be described as a famous family, and he and Cai Kuo should be placed in similar positions as the Three Dukes, let alone those holding higher ranks."
