Angbuilgu is a kind of sundial and is constructed in the shape of a hemisphere. 13 parallel lines of latitude represent the 24 solar terms from the winter solstice to the summer solstice, and time lines are drawn vertically. A shadow rod is pinned down at an angle toward Polaris and a mythic symbol is drawn for each of the hours for those people who could not read.The main construction material is bronze and the letters and lines are engraved with silver on a black lacquer background to ensure that they can be clearly seen. Four legs stand on a cross for balance.Considering the drawn lines, Angbuilgu was presumably made after 1636. By looking at its measurement of altitude of Hanyang (Old Seoul), Angbuilgu is estimated to have been produced in the early 18th century.
