Samguk Yusa (Memorabilia of the Three Kingdoms) was compiled by the Buddhist monk Iryeon (1206-1289) in 1281 (the seventh year of the reign of King Chungnyeol) in the late Goryeo Period. It included many matters that were not covered by existing literary works such as Samguk Sagi (History of the Three Kingdoms) or Haedong Goseungjeon (Lives of Eminent Korean Monks). Along with Jewangungi (Song of Emperors and Kings), this book establishes Dangun Joseon as the starting point of the country’s history. It is a highly useful material for study of the country’s ancient culture.
