新近出土的隋大業九年（613）《豆盧賢墓誌》業已刊佈，研讀之餘，感覺尚有再討論之問題，因就豆盧氏之族源與其姓氏變化因由、豆盧賢之宗教信仰和豆盧氏之支脈與族塋及隋代墓誌銘所見撰書人署名之梳理與分析而略作闡發。其一，以誌史互證，可知豆盧氏爲鮮卑族慕容燕之後裔，北魏皇始二年（397）歸魏，至天賜六年（409）慕容氏謀叛伏誅，其倖免者或改稱「豆盧」意謂「歸義」焉。而豆盧氏不見於《官氏志》，當是以「吐伏盧氏後改爲盧氏」，而「吐伏盧氏」卽「豆盧氏」音轉之異的緣故。至於復姓與單姓之變化，蓋爲北魏改豆盧爲盧，西魏復舊，入唐又嘗改爲單姓焉。其二，《唐智該法師碑》所記豆盧賢禮敬智該法師一條，當是值得重視的可資窺見豆盧賢宗教信仰的碑刻史料。作爲支脈的豆盧賢一族在隋唐時期的政治地位與社會勢力雖已趨於沉淪，而其祖塋所在的「京兆郡涇陽縣之洪瀆原」卻依然是子孫的歸葬地。其三，相較於南北朝墓誌尚少有撰書者署名的情形，在隋代墓誌銘中逐漸出現的撰書者署名現象，應是一種直接影響了盛唐以後流行起來的墓誌撰書者署名時尚的文化趨勢。並可見證周隋時期投北之南人多係南朝與北齊經史傳家之文學世族，且以南人爲夥。而藉由銘文的音韻又適可研討失傳的隋代《切韻》的韻部與聲律，以及見證當時受南朝學風影響且更偏愛文學的時代流行風尚，乃至散體文向格律詩發展的文體流變和愈加明顯的文學辭章重視聲律的導向。

The newly unearthed “Doulu Xian’s Epitaph” of the 9th year of the Dajye period (613) of the Sui dynasty has been published. After studying, we think there are issues that need to be discussed again. In this paper, we will explain the following issues: the origin and surname of the Doulu clan, the religious beliefs of Doulu Xian, the branch of the Doulu clan and their ancestral grave, and the phenomenon of the author signing his name on the epitaphs of the Sui Dynasty. Firstly, the Doulu clan is a descendant of Murong Yan, a Xianbei nation. They defected to the Northern Wei in the second year of Huang Shi (397). In the sixth year of Tianzhi (409), some of the Murong clan were killed for rebellion. The survivors were renamed “Doulu”, with the meaning of “return to the righteousness”. The book of Wei Shu - Guan Shi Zhi records: “Tu Fu Lu's changed to Lu’s”, “Tu Fu Lu’s” is actually “Dou Lu’s”. The Northern Wei Dynasty changed “Dou Lu” to “Lu”, and the Western Wei Dynasty changed to “Dou Lu”, and then changed to “Lu” in the Tang Dynasty. Secondly, the “Tang Zhigai Venerable Tablet” records Doulu Xian’s respect to Zhigai Venerable, which should be valued as a historical inscription that provides a glimpse of Doulu Xian’s religious beliefs. Although the political status and social power of the Doulu Xian clan during the Sui and Tang dynasties tended to sink, their ancestral graves were located in the “Hongdangyuan in Jingshao Shire, Jinyang County” but remained unchanged. Thirdly, there were very few cases in which the writer signed his name in the tombstones of the Northern and Southern Dynasties, and this phenomenon gradually emerged in the Sui Dynasty, which directly affected the cultural trend became popular in the flourishing period of Tang Dynasty. During the Northern Zhou and Sui dynasties, most of the southerners who moved to the north were cultural clans proficient in Confucianism and history. The phonetic rhyme of tombstone inscriptions can help us to recognize the lost “Cheyun” of the Sui dynasty, which shows that the popular trend at that time was heavily influenced by the Southern dynasty, with a preference for literature; prose developed towards metrical poetry, and emphasis was placed on meter.
