The Sacheon Collection of Poems is a collection of paintings made by Lee Sin- heum(1570-1631), who was associated with the farm villa Sacheonjang and with the gyehoe(fraternity association gatherings) of Lee Ho-min(1553-1634) and his son Yi Gyeong- eom(1579-1652), both of whom were men of letters during the mid-Joseon Period. The collection also includes poems and calligraphic works composed by contemporary men of letters. It consists of four volumes of poems about the four seasons and a volume about gyehoe. This study came up with the following findings as a result of examination of the contents and style of the book: First, it is thought that the designation of eight scenic views(palgyeong) near Sacheonjang, and Lee Sin-heum’s Sacheonjang Palgyeongdo(Painting of the Eight Scenic Views of Sacheonjang) were all made in or about 1616, at a time when Lee Gyeong-eom was operating the villa. Second, it is thought that the three pictures of deities taking their leisure and of flowers and birds, which appear along with Sacheonjang Palgyeongdo at the first part of each volume of the collection, have nothing to do with Sacheonjang Villa but had been done at the time of Lee Sin-heum’s Senyeon Gyehoedo(Painting of a Gathering of Fraternity Association Members) in 1604. The belief that these pictures had been painted during that session is based on records about the painting of pictures of flowers and birds of Yeonjudongnyeon Gyehoecheop and Gim Hong-do’s Ajipdo(a picture of a gathering of 16 well-known artists at Wang Shen’s house during the Northern Song China period), Third, the two pictures, Sacheonjang Palgyeongdo and Senyeon Gyehoedo, portrayed scenes in Yangpyeong, Gyeonggi-do and in Anguk-dong and Samcheong-dong, Seoul, and the scenes correspond to present-day scenes there. They portray the several places on one scene, with each scene portrayed in detail from diverse perspectives. This mode of composition is thought to have something to do with those of Hainei qiguan(Marvelous Sights within the Empire) or with the Sancai tuhui, a richly illustrated encyclopedia from the Ming period compiled by Wang Qi. The significance from an art history perspective found from the form and style used in Sacheon Collection of Poems is as follows: First, the collection, which was made in the early 17 th Century, is the only material available for those studying the history of fine art that contains a picture of a farm villa, a picture of a fraternity association gathering(gyehoedo), a picture of flowers and birds(hwajohwa), a picture of a landscape and figures, and poems associated with the subjects of the pictures. The book makes it possible to look at poems, other writings and pictures produced by people of letters in the 17th Century and at how these people mingled with each other, and in addition, how topographic landscapes were painted in the mid-Joseon Period. It is particularly noteworthy that Sacheonjang Palgyeongdo is the only real landscape painting available of a place in Yongmunsan Mountain, Yangpyeong, which was noted as a site of farm villas belonging to well-known men of letters. Second, the status of production of gyehoedo in the mid-Joseon Period can be examined, along with the characteristics of hwajohwa, landscape pictures, and figure pictures, which are all thought to have been made along with Senyeon Gyehoedo. This made it possible to get a better understanding of Yeonjudongnyeon Gyehoecheop, in which hwajohwa appears instead of gyehoedo, and lays the basis for thinking that hwajohwa, landscape pictures, and figure pictures were all equally recognized as objects that reflected ideal values of people of letters. Third, the collection makes it possible to examine in detail chronological and style- related characteristics of the paintings of Lee Sin-heum, a leading painter of the mid-Joseon Period.
