Wine Ewer with Incised Bamboo Shoot Design, 1100s. Natural motifs inspired the shape of celadon vessels as well as their inlaid designs in the Goryeo period. This wine ewer is shaped like a bamboo shoot, but it also resembles a lotus bud. Even though the spout was repaired, the ewer is a masterpiece of Goryeo period celadon. Ewers of the same shape are now housed at the National Museum of Korea and the Museum of Oriental Ceramics, Osaka.
