The sundial of the Joseon Dynasty in a form that was not known until now was released for the first time.

It has a round globe-like shape, so you can check the time anywhere in the northern and southern hemispheres, and you can carry it around with you. 



Reporter Lee Joo-sang reports.

It is a small globe-shaped sundial with a diameter of 11.2 cm and a height of 23.8 cm including the pedestal.



The hemispherical Angbuilgu, made during the reign of King Sejong the Great, had to set the engraving needle toward the North Pole, so it was possible to know the time only in certain places.



By the way, this Ilyeongwongu is a portable sundial.



Time is indicated by turning the sphere so that the shadow of the elongated 'T' hour hand fits into the groove below.



In particular, the characteristic of Ilyeongwon-gu is that there is a time signal window separate from the hour hand.



A text will appear on the round window indicating what time it is.



Also, the lower part of the sphere faces the South Pole, not the North Pole, so you can measure time anywhere on Earth, including south of the equator.

the West, there is a sundial with a simple round shape.



The name of the manufacturer is also engraved.



Sangjik-hyeon was a military officer who was in charge of the king's escort and palace defense, and it is estimated that he came into contact with various cultures through the experience of the Japanese Shinsinsa.



[Lee Yong-sam / Professor Emeritus of Chungbuk National University: It can be evaluated as a luxury sundial with historical value and artistic dignity as well as various scientifically sophisticated functions.]



It is unknown how Ilyeongwon-gu went abroad, but it was sold at an auction in the United States last March. The Overseas Cultural Heritage Foundation won the bid on the site and returned to Korea.
