Samgungnyusa
Samgungnyusa, Samguk Yusa (Korean pronunciation: [sʰamɡuŋ njusʰa]) or Memorabilia of the Three Kingdoms is a collection of legends, folktales and historical accounts relating to the Three Kingdoms of Korea (Goguryeo, Baekje and Silla), as well as to other periods and states before, during and after the Three Kingdoms period. It is the earliest extant record of the Dangun legend, which records the founding of Gojoseon as the first Korean nation.
Authorship and date
The text was written in Classical Chinese, which was used by literate Koreans at the time of its composition. The earliest version of the text is believed to have been compiled in the 1280s, and the earliest extant publication of the text is from 1512 CE.
20th-century Korean scholars such as Choe Nam-seon established the Buddhist monk Iryeon (1206–1289) as the main compiler of the text, on the basis that his name (and full official title) was indicated in the fifth fascicle. This view is widely accepted among modern scholars. The compilation is believed to have been expanded by Iryeon's disciple Muguk (1250-1322) and several others prior to the definitive 1512 recension.
