Abstract

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.
