Summary

This study investigated the characteristics of a Western-style horizontal sundial (T840) from the Joseon Dynasty to estimate its latitude and gnomon length. The latitude estimated based on hour-lines and solar-term-lines showed a 24' difference from the recorded latitude (37 degrees 39'), and the gnomon was found to be vertical. The gnomon length was statistically calculated as 43.7 +/- 0.7 mm, which is similar to the value engraved on the artifact (43.1 mm).
