Long-necked jar with geometric decoration, Korea, South and North Kingdoms period, Unified Silla (676–935), 7th–8th century. Stoneware with stamped design and incidental ash glaze, H. 10 7/16 in. (26.5 cm), L.2016.43.6a, b. Photograph courtesy the National Museum of Korea

The densely packed, abstract design on this jar was created by impressing stamps onto the clay body. The effect is mesmerizing. This vessel both continues and amplifies an earlier penchant for geometric patterns, as seen in burial pottery from the fifth and sixth centuries displayed in these cases. Stamped surface ornamentation also characterizes Buddhist cremation urns from the Unified Silla kingdom.
