The purpose of this paper is to examine how late Joseon art scene interpreted and reflected the concept of “The four masters of Yuan dynasty (元四大家, from this out I’ll mark it as a Yuan-sadaega)” into landscape paintings during the late 18th to the first half of the 19th century. This study employs a comparative approach, analyzing paintings created during this period in Korea and China, particularly those featuring Yuan-sadaega, while also investigating written records. The understanding of the Yuan-sadaega and their paintings began through the early 17th century Gosi's painting manuals(顧氏畵譜). Through Heo Guseo (許九敍)'s works and literary records, It can be observed that the perception of Yuan sadaega's artworks and artistic aspects during at least the late 18th century was established within the art community. Notably, a distinct shift in the understanding of painters and the composition of Yuan-sadaega is observed in the trends of the late 18th and first half of the 19th century. In the late 18th century, the use of dwelling in the mountain(山居) image into landscapes in Yuan-sadaega compositions is evident, particularly in works by artists like Won Myeong-ung(元命雄) and Jeong Su-yeong(鄭遂榮). This trend is rooted in the contemporaneous significance of the art scene that produced a variety of paintings with the theme of ‘benevolence and daily life and in the shared understanding of the Yuan-sadaega as recluse(隱士) within the artistic community. This collective perception of the Yuan-sadaega seems to have been influenced by the influx of theories and writings on painting by Dong qi chang(董其昌) and by the circulation of painting manuals. The early 19th century, a new a new type of painting emerged alongside Bangjak(倣作, paintings of creative imitation) about the Yuan-sadaega, known as ‘Bangjak about Yuan dynasty painters(倣元人山水圖). Through the works of Kim Jeong-hee(金正喜) and Heo Ryeon(許鍊), it is noteworthy that various scenes are depicted under the same theme. This reflects the establishment of universal values and standards for literary painting within the art community. This process led to the term ‘Ni-hwang(倪黃, abbreviation of Ni zan and Hwang gong wang)’ emerging and the concept expanding under the term ‘Yuan-in’ (元人, the symbol of Yuan art scean). As a result, the desired artistic style pursued by the contemporary artistic community was encompassed under the universal concept of ‘Yuan-in,’ and ‘Bangjak about Yuan dynasty painters’ came to embody this comprehensive theme
