作为查理曼的继承人，虔诚者路易的统治上承统一强大的国家，下接内
战和国家的衰弱分裂。因此，在不同学术范式和历史文献所构建的历史叙事中，路易有着多种不同的历史形象。综述学术史，可知已有的历史叙事主要有启蒙叙事，民族浪漫主义叙事，封建主义叙事等几种。路易统治时期是加洛林文艺复兴的一个繁荣期，同时代和之后几十年间，许多宫廷史家都称赞他的统治兼顾了圣事（ecclesia）与公事（publicus）。通过文本分析和概念分析和历史事实分析，本文认为“兼顾圣事与公事”的时代历史书写也塑造了一种新的历史叙事，以良好的政治秩序和君主职责的履行为其核心。当然，这种历史叙事同前面几种一样，其塑造的路易的形象都是片面且失真的。

本文分为以下几个部分。第一部分，综述虔诚者路易研究的史学史以及在其基础上形成的几种比较主流的描述其统治的历史叙事。第二部分，从概念史角度出发，辨析和讨论“ecclesia”和“publicus”这一对概念的本意、词源和他们在这个转型期发生的具体内涵变动。进而对这种历史叙事的内在逻辑加以把握。与此同时，讨论虔诚者路易时期土地争端、政治斗争中的现实的“公事”和“圣事”关系，指出这两个概念对君主的共同要求是正当秩序，而这种“维持正当秩序”的能力是本文讨论的历史叙事的核心。第三部分，指出“兼领圣事和公事”的历史叙事模型的理想性和对路易的过度美化，及其背后反映的同时代统治者的复杂权力意图。

As Charlemagne's heir, the reign of Louis the Pious started with the powerful country, but ended up with civil war, division and decline. Therefore, he has different historical image in different historical narratives constructed by different academic paradigms and historical documents. By summarizing the academic history, we can see that the existing historical narratives mainly include
enlightenment narrative, national romantic narrative, feudal narrative and so on. The reign of Louis was also a boom of the Carolingian Renaissance, so many court historians praised his reign for both The Ecclesia and The Publicus, even some decades after his death. Through text analysis, conceptual analysis and historical
fact analysis, this paper holds that the historical writing of "giving into account holy and business" has also shaped a new historical narrative, with good political order and the performance of sovereign duties as its core. Of course, this historical narrative is like the previous ones, and the image of Louis is one-sided and
distorted.

This paper can be divided into the following sections. The first part is a review of the historiography of Louis the Pious and several mainstream historical narratives describing his rule which formed in this historiography. The second part, from the perspective of conceptual history, analyzes and discusses the original meaning and etymology of "ecclesia" and "publicus" and theirspecific connotation changes in this transition period. And then to grasp the internal logic of this historical narrative. At the same time, discussing the relationship of "ecclesia" and "publicus" in the historial reality, for example, in land dispute and political struggle
during the Louis period of the pious.Then point out that the common requirement of these two concepts on the monarch is the proper order, and the ability to "maintain the proper order" is the core of the historical narrative discussed in this paper. The third part points out the ideality of the historical narrative model of
"Tam ecclesiastica quamque publica" and the excessive idealization of Louis, and the complex power intention of the coetaneous rulers reflected behind it.
