A general study on formation and metamorphosis of war chronicles

战争编年史是一部流动的作品，它总是在改变它的形式。在本研究中，我主要分析了《Heike Monogatari》，考察了这些作品是如何形成的，以及大量不同的手稿是如何诞生的。主要的研究成果是，通过理清各种手稿之间的关系，考虑在各种手稿的背景之外存在着什么样的文学方法差异，获得了将各种手稿的流动表现为文学史的基本观点。

War chronicles is a fluid work, which has always changed its form. In this study, I analyzed mainly "Heike Monogatari" examining that how these works had been formed and immense numbers of various manuscripts had been born. The main research result is that I obtained basic point of view to express the fluid of various manuscripts as a history of literature by clarifying the relationships between various manuscripts and considering what kind of differences in literary method exists beyond background of various manuscripts.
