Jeong Cheol (Songgang)
Also called: Songgang
Master of gasa verse who wrote the Gwandong byeolgok and Samiingok; as a Westerner he ran the Jeong Yeo-rip treason inquiry
A leading Westerner, he took charge of the inquiry after the Jeong Yeo-rip treason case of 1589 and harshly punished Yi Bal and other Easterners (the Gichuk Purge). In 1591 his proposal to name Gwanghaegun crown prince angered Seonjo and he was exiled, and the question of how to punish him split the Easterners into Southerners and Northerners. His gasa such as the Gwandong byeolgok, written as governor of Gangwon, and the Samiingok and Sok-miingok, and sijo such as the Hunminga make him a master of Korean-language verse.
