This earthenware, depicting a horseman, is of the Three Kingdoms Period (fifth century). It is 23.2 cm tall and 14.7 cm wide with a 9.2 cm base.
A warrior riding on a horse is on top of the rectangular plate, which is balanced over the horn-shaped footing. The footplate has a similar shape to the kobae, a mounted cup, of the Gaya Kingdom. There are hand crafted horse legs on the footplate's four corners. Detailed armor is on the horse's body, and the mane of the horse is sculpted in a straight line. An armored warrior is sitting holding a weapon on top of the horse. The warrior is wearing an armored head cover, has a spear in the right hand, and a shield in the left hand. Detailed patterns are carved on the surface of the shield, which has not been identified yet. Two horn-shaped cups are mounted on the back of the warrior.

This piece of work is very valuable, but its illustration of weaponry from the Gaya Kingdom is by far the most important material for research.
