- The name of gwancheondae(觀天臺) means a sky- observing stand. It was a stand
for ganeui(簡儀: a kind of torquetum) or soganeui(小簡儀: a kind of small
torquetum). The name of ilyeongdae(日影臺) means sun- shadow stand. It was a
stand for ilgu(日曇: sundial) or ilseongjeongsieui(日星定時儀: a kind of astrolabe).
Ilseongjeongsieui was an astronomical clock used for checking the nearby clepsydra
for clay and night.
There is a stone stand designated for treasure No. 851 inChanggyeong Palace(昌
慶宮). It is known as a gwancheondae for soganeui, but it is not a gwancheondae
but an ilyeongdae for ilseongjeongsieui.
It is the only stand for ilseongieongsieui, and the stone stand located in Hyundae
office building in Gye-rdong is the only stand for soganeui remained till now.
