Engraved Shard from Omachida Site

Yayoi – Kofun period (300 BCE- 552)

This shard was excavated in the pit at Omachida with other non-engraved shards. Although the shard is only a quarter volume of the whole pottery artifact, it is estimated that artifact might have been a jar or a bowl and probably made in the local area.

Two bird-shaped men (or women) are engraved on the surface of the shard. This may depict some kind of a ritual activity in ancient times.
