I explore the pyeongjeom commentary by Choi-hae(崔瀣, 1287~1340) included in Samhanshiguigam(三韓詩龜鑑). Pyeongjeom commentary, which maximizes the dialogical relationship between writter and critic, is a peculiar way of criticism developed in the East Asia. However, studies on pyeongjeom commentary are not sufficient yet, and concentrated on the pyeongjeom commentary of late Choseon period. I intend to fill the void in the field of study of Korean traditional criticism written in classical Chinese. This study begins with examining the morphometric characteristics of the pyeongjeom commentary included in Samhanshiguigam. Next, this study discusses the background of the pyeongjeom commentary included in Samhanshiguigam. Especially, I pay attention to how ‘China=the external’ and ‘Korea=the interal’ are interweaved closely. Based on the two aspects mentioned above, I explore the pyeongjeom commentary by Choi-hae included in Samhanshiguigam. I examine how Choi criticized the poems included in Samhanshiguigam and which poetical tradition he succeeded. Finally I examine a historical meaning of Choi’s criticism included in Samhanshiguigam in a broader context. Samhanshiguigam, which is based on the selection of Korean traditional literature written in classical Chinese Donginjimun(東人之文), is the prototype of pyeongjeom commentary in premodern Korea. Pyeongjeom commentary included in Samhanshiguigam is the case of the initial stage of history of Korean traditional criticism as the appropriation of Chinese literary criticism through transforming it as an important way of organizing domestic literary tradition.
