The portable hemispherical sundial, alternatively designated as hemispherical sun-shadow timekeeper, derives its nomenclature from its resemblance to a cauldron facing heavenward toward the sky. This astronomical timekeeping device was initially created in 1434 by artisans Jang Yeongshil, Yi Cheon, and Yi Sunji pursuant to royal directive, with installation occurring in October 1434 at two locations—before Jongmyo Shrine and at Hyejeong Bridge—thereby establishing the foundational design tradition. Subsequently manufactured in diverse configurations throughout the late Joseon period, hemispherical sundials achieved widespread distribution throughout imperial palaces, governmental administrative offices, and private residences. Hemispherical sundials exist in two functional forms: stationary installations and portable handheld versions. The designated example represents the latter portable handheld configuration. The Seoul History Museum's portable hemispherical sundial employs a hemispherical concave depression on the surface with a gnomon positioned at the central point, alongside an attached magnetic compass device positioned to ensure precise cardinal-directional alignment permitting accurate time measurement. The designated work demonstrates superior technical execution through precisely calibrated hemispherical surface curvature enabling precise production of distinct seasonal lines and temporal demarcations. The gnomon, fabricated from white copper and gilded with silver coating, exhibits superior craftsmanship. Engraved notations on the basal surface document creation date (Yongxi second year, 1908) and artisan designations (craftsman Kang Munsu), establishing this work as produced by the Jinju Kang family lineage, historically prolific hemispherical sundial manufacturers, thereby possessing elevated scientific-historical documentary value.
