The Wooden Ksitigarbha Bodhisattva Triad and Ten Underworld Kings enshrined at Musajeon Hall of Heungguksa Temple in Yeosu were created in 1648 (the 26th year of King Injo’s reign), by 12 monk sculptors under the master sculptor Ingyun. The Ksitigarbha has an impressive expression on the fleshy round face, gazing upward from under swollen eyelids. The body is nicely curved with a sense of volume, enhanced by the pleasant harmony of the straight and bent lines of the folds of the robe. The Ten Underworld Kings and attendant figures have lively expressions, suggestive of their respective roles and different attributes. These sculpted images successfully reflect the Buddhist iconography of the 17th century. Their value is heightened by the existence of all the images carved together and a letter of invocation revealing the situation surrounding their creation.
