读司空图《荥阳族系记序》札记

A Note to the Preface of XingYangZuXiJi by Sikong Tu

司空图序中所提到的三部私修谱书都是唐玄宗时人所撰,其中《荥阳族系记》作者郑回与南诏清平官郑回为同一人。《新唐书·宰相世系表》述郑氏谱系,疑曾取资于郑回之谱。可见该序确出司空图,而且很有史料价值。

Three genealogical books mentioned by Sikong Tu in the preface were edited in the period of Tang Xuan Zong. As one of editors, Zheng Hui who edited Xing Yang Zu Xi Ji was the man who was appointed the prime minister in South Zhao. The genealogical tree of Zheng in New Tang Book may use the material in his book.
