Budoji

Budoji is a pseudo-historical work on East Asian and Korean culture written by Bak Geum (박금) in 1953, that claims to be a recollection of the contents of the original Budoji, which is supposedly one of the 15 books in a collection called Jing Shim Rok  that has been passed down from the period of the Silla dynasty. Bak Geum states he left the Jing Shim Rok in the North on his escape to South Korea during the North-South Korean war, rewriting the current Budoji from memory after his escape.

The Budoji is claimed to have been the first of the 15 books of the Jing Shim Rok with its focus on ancient history. The original Jing Shim Rok is told to have been written by Bak Jae Sang (박제상) during the Silla dynasty and passed down in the Bak family, and finally to Bak Geum before its loss during his escape to South Korea. The book is considered to be part of a pseudo historical narrative and is widely considered false by mainstream historians.

The Era of Mago
The first era of Korean history according to the book is called Mago (마고,麻故). Budoji states that there were four Heavenly people, who were Hwanggung (황궁, 黃穹), Baekso (백소,白巢), Cheonggung (청궁,靑穹) and Heukso (흑소,黑巢). The mother of Hwanggung and Cheonggung was Gungheui (궁희, 穹姬), and the mother of Baekso and Heukso was Soheui (소희,巢姬). The mother of Gungheui and Soheui was Mago. It is said that Mago, Soheui and Gungheui bore children without a father.
