一般认为柴姓起源于高柴,但唐以前的姓氏著作中却没有提到柴姓,且史书所载唐以前柴姓人物很少。本文通过对传世文献、墓志材料中有关柴、陈二姓关系的考证,以及从语音上对柴、陈两字的分析,结合敦煌文献,否定了前人的说法,认为柴姓出自陈姓,至唐中后期最终从陈姓分出,成为独立的姓氏。 It is generally believed that Chai name originated from Gao Chai, but no previous name surnamed Chai was mentioned in Tang’s writings. Through the textual research on the relationship between Chai and Chen Er-chen in the handed down documents and the epitaph materials, as well as the analysis of the two characters of Chai and Chen from the phonetic features and the Dunhuang literatures, this article negates the predecessors’ In the late Tang Dynasty eventually separated from the surnamed Chen, an independent surname.
