Samguk Yusa

Samguk Yusa (삼국 유사 (三國遺事) in Korean) is a collection of legends, folktales, and historical accounts relating to the so-called Three Kingdoms of Korea (Goguryeo, Baekje and Silla), as well as to other periods and states before, during, and after the Three Kingdoms period.

The text was written in Classical Chinese (as used in writing by literate Koreans at that time) by the Buddhist monk Ilyon at the end of the 13th century, a century after the Samguk Sagi.
