Reliquaries with depictions of the Four Heavenly Kings began to appear in 682 during the Unified Silla dynasty, continuing until the Goryeo dynasty (918–1392). These images usually appear in relief on the four sides of a reliquary as a symbol of protection.
This reliquary was not discovered inside a pagoda, but in a square stone casket buried in the side of a mountain. Each of the Four Heavenly Kings has a nimbus and a mandorla. The square lid has a raised lotus bud at the center and is decorated with floral and vine patterns.
