This celadon jar with an inlaid lotus, reed and waterfowl design was made around the late thirteenth century. The jar is characterized by a unique, flat shape on two of the four sides of the body, which is closer to the style of the Yuan Dynasty of China rather than the typical style of Goryeo. Around this time, the political influence of the Yuan Dynasty increased dramatically, which in turn influenced Goryeo’s culture and customs. That’s why the shapes or patterns of Goryeo celadon made at that time partially exhibit the styles of the Yuan Dynasty.

The flat sides of the body are decorated with an inlaid doubled-water chestnut window pattern containing a waterside scene composed of a lotus flower, lotus leaf stem pattern, bird, willow, and reeds. Both the narrow and round sides of the body feature a design depicting two birds tidying their feathers or playing peacefully under a tree with fruits.
