Jeong Yak-yong (Dasan)

Silhak scholar who helped design Hwaseong; exiled to Gangjin, where he wrote the Mongmin simseo

A Southerner, he carried on Yi Ik's learning and brought Silhak to its height. Trusted by Jeongjo, he designed the crane (geojunggi) used to build Hwaseong Fortress and a pontoon bridge over the Han. Exiled to Gangjin in the Catholic Persecution of 1801, he spent 18 years there writing the Mongmin simseo on the duties of local officials, the Gyeongse yupyo on reforming central institutions and the Heumheum sinseo on criminal law. He proposed the yeojeon system, in which villages would farm land jointly and share the harvest by labour. He also wrote the Magwa hoetong and the Abang gangyeokgo; his works are collected in the Yeoyudang jeonseo.
