As part of efforts to systematize Joseon’s state rituals, the Five Rites appended to the Annals of King Sejong were compiled in 1454, based on various experiments and studies conducted during the reign of King Sejong (r. 1418–1450). This compilation was later revised under King Sejo (r. 1455–1468) and finalized in 1474 as the Gukjo oryeui (Five Rites of the State), in the fifth year of King Seongjong’s reign. The Gukjo oryeui seorye was subsequently compiled as an expanded edition, incorporating statistical data and detailed diagrams that explain the components of ritual practice. The Five Rites were grounded in the practical experience accumulated during the Sejong era, reflecting actual ceremonial practice. Illustrations of ritual vessels were included, depicting both their form and function. Among the five categories, gillye (auspicious rites)—which accounted for the majority of royal ceremonies—was the first to be codified. Its accompanying diagrams of ritual vessels present detailed images and descriptions of the various types of objects used in state rites.
