Mado Shipwreck N°3 Janggi Stones

Les "pierres" coréennes de l'épave Mado n°3

The oldest known janggi pieces have been found in a shipwreck (known as Mado shipwreck N°3) which sunk at the end of the Goryeo period, between 1265 and 1268, in the waters of Mado (Taean county, South Korea) en route to Ganghwado, the temporary capital at the time. They simply consist in mere pebbles with rounded edges and Chinese characters painted with ink on one face. They are conserved at the National Research Institute of Maritime Cultural Heritage, Jeonnam, Republic of Korea.
