초록

This study analyzes the characteristics of the Angbu-ilgu, a Korean sundial resembling a concave hemisphere, which was crafted in 1434 during the sixteenth reign of King Sejong (r. 1418-1450) of the Joseon Dynasty, although no remains of it exist today. We draw upon historical documents, such as the Sejong-Sillok (Veritable Records of King Sejong), Donggyeong-Jiji (Chorography of the Joseon Dynasty), and Yuanshi (History of the Yuan Dynasty), as well as related extant relics. The primary features of King Sejong's Angbu-ilgu were as follows. First, celestial-circumference degrees were intricately engraved along the meridian line. Second, 12 double-hours were represented by images corresponding to their respective animal divinities. Third, a plate was affixed to the end of the gnomon, which stood perpendicular to the alidade, serving as a handle, rotated along two axes, and included a pinhole. Fourth, the diameter of the hemisphere measured 414 mm, approximately 1.5-2.1 times larger than extant Angbu-ilgu relics. Finally, four pillars supporting the Angbu-ilgu were positioned at four cardinal points. In conclusion, this study holds significance for restoring the Angbu-ilgu from the era of King Sejong.
