A Preliminary Study on the Yang-cheon-cheok (量天尺) in the Late Joseon Dynasty
We investigated the six remaining Yang-cheon-cheoks (量天尺), which were first described in the Veritable Record of King Sukjong (肅宗實錄). These woodblock sundials from Korea are structurally very similar to a Gyupyo (圭表, gnomon) or an altitude sundial and are light, compact, and portable. The front si...

| description | We investigated the six remaining Yang-cheon-cheoks (量天尺), which were first described in the Veritable Record of King
Sukjong (肅宗實錄). These woodblock sundials from Korea are structurally very similar to a Gyupyo (圭表, gnomon) or an
altitude sundial and are light, compact, and portable. The front side of a Yang-cheon-cheok has two holes for styluses and
several hour-lines. We compared the intervals of the hour-lines from the originating point of the stylus placement on all
Yang-cheon-cheoks and found that two of the relics had the same hour-lines using the standard of the unit of 1 chon (寸).
These two were actually the same sundial although the physical size was different. In spite of the lack of time accuracy, we
hypothesize that various-sized Yang-cheon-cheoks were made and widely distributed throughout the public in the late
Joseon Dynasty. |
