“冉牟墓志”是少有的保存下来的高句丽人自己书写的文字史料之一,由于文字漫漶,难以卒读,因此其史料价值长期未能得到有效发挥。从耿铁华先生的最新释文看,墓志主人确是冉牟,书写者则是其孙牟头娄。墓志记述了冉牟的生平事迹,以及其家族,包括牟头娄所受到的历代高句丽王的恩赏。从历史研究的角度看,墓志残存内容有助于我们理解高句丽王权与贵族阶层的关系,贵族阶层内部的分化,以及高句丽对北夫余的征服与统治等问题。 “Ran Mou Epitaph ” is one of the few preserved historical materials written by the Gaogouli people, whose historical value has not been able to be effectively used for a long time due to the diffuse passage of text. According to the latest interpretation from Mr. Geng Tiehua, the owner of the epitaph is indeed Mu Mou, and the writer is his grandchildren Lou. Epitaph recorded the life story of Ran Mu, as well as his family, including the Mu Kou Lou suffered by the King Goguryeo’s appreciation. From the perspective of historical studies, the remnants of the epitaphs help us to understand the relationship between the Kao-Gori royal power and the aristocracy, the internal differentiation of the aristocracy, and the conquest and rule of the Northern Kofee Goguryeo.
