The variety of shapes and decorative styles of Buddhist ritual objects attests to the diversity of material culture in the Koryo (918–1392) dynasty, as well as the wealth of the state-sponsored Buddhist establishment. The refined lines and balance of this large bronze incense burner epitomizes the exquisite sense of proportion that characterizes the arts of the period. A superb example of Koryo inlaid metalwork is an incense burner dated 1289, whose chalice shape with a wide, flat rim was popular into the succeeding Choson dynasty (1392–1910). Enclosed within the four foliate panels are dragons and phoenixes, which, though not particular to Buddhism, are auspicious symbols appropriate for such a ritual object.
