Abstract

This study is about the basis for restoring the folding screen the Astronomical Chart Showing both the Traditional Joseon and Western Styles, a treasure held by the National Folk Museum of Korea, which consisted of eight individual pieces. Conservation treatment was conducted in 2000, a year before it was designated as a treasure, but since the original shape of the folding screen was unknown at that time, only the damaged parts were treated and conserved separately. However, during the exhibition, issues arose during exhibition due to the display of the panels as individual pieces, making the restoration of the screen mounting a priority. Over several years, we researched other examples of the astronomical chart showing both the traditional Joseon and western styles, and found a total of nine cases existed. We conducted a scientific analysis of the coloring material composition and iconography of the six cases, and found a case that is believed to have been produced at the same time as the treasures the Astronomical Chart Showing both the Traditional Joseon and Western Styles owned by the National Folk Museum of Korea. The oldest versions of the six cases are the Astronomical Chart Showing both the Traditional Joseon and Western Styles (Treasure) owned by the National Folk Museum of Korea and the edition in Whipple Museum of History of Science. The production time is estimated to be after the mid-18th century. However, in the edition in The National Library of the National Assembly of Japan, two editions in the National Museum of Korea(Bonguan 10968, Deoksu 1218), and another edition in National Folk Museum of Korea(Minsok 70195), emerald green and ultramarine blue introduced from Europe after the mid-19th century were detected in the painting, showing a temporal difference from the previous two cases. The size and structure of original folding screen were estimated through the folding screen’s inner frame paper attached to the back of the original edition of the Astronomical Chart Showing both the Traditional Joseon and Western Styles owned by the National Folk Museum of Korea. In addition, in terms of materials, the materials of the folding bordering(回粧) and folding screen robe(屛風衣) were identified through scientific composition analysis and applied to the restoration. Since it was not possible to obtain contemporary information, the restoration of trimmings in the bottom(下繪粧) was designed using indigo dye silk by referring to the National Museum of Korea's edition(Deoksu 1218), which maintained its original mounting form despite the differences in time. Based on the design, conservation treatment and restoration of the folding screen were carried out in 2023. This study identified the time and materials of the astronomical chart showing both the traditional Joseon and western styles through scientific analysis. We hope that this will be helpful in researching relics related to astronomy in the future or restoring folding screens of the astronomical chart showing both the traditional Joseon and western styles of similar times.
