Śākyamuni’s right arm curves and his hand touches his head. Rarely seen elements such as the large-scale hairstyle and prominent facial features, as well as the body with its lack of modulation and broad shoulders, are reminiscent of the gilt-bronze buddhas created on the Korean peninsula during the Three-Kingdoms period. The work evokes a palpable presence despite its small size and simple style.

The moment after his birth, Śākyamuni Buddha took seven steps and declared, “In heaven and on earth, I alone am the World-Honored One.” This iconography reflects that moment in the Buddha’s biography. Statues like this one are used in the Bathing of the Buddha, a ceremony held on April 8th, the day celebrated as Śākyamuni’s birthday. The proportions of this endearing statue—particularly its relatively large head—are modeled after those of an infant.
