An Introduction of Korean Classic   Despite being “the best-selling fictional narrative during the late Chosŏn period” (1392-1910) of pre-modern Korea, little is known about the provenance of The Tale of Cho Ung. The author remains unknown and its initial composition has been narrowed down to a 200-plus-year-window, with a guesstimate falling somewhere between the late-18th to early 19th centuries.
