So, King Taejo ordered royal astronomers to carve the constellations which are suitable for Korea's latitude and longitude on a flat black stone in December, 1395.

The engraved stone shows the 1,467 stars visible from Korea,[1] 264 constellations and their names, the ecliptic and equatorial lines, and 365 scales around.

[2] The chart shows positions of the heavenly bodies in their natural order, allocated on their respective celestial fields.

This map became standard during the Joseon dynasty, with numerous copies printed and disseminated throughout the kingdom, until it was superseded by Western planispheres in the nineteenth century.

[2] The map is now used as a background image on the reverse of the 2007 issued 10,000 won banknotes and was featured in the opening ceremonies of the 2018 Winter Olympics in PyeongChang.
