Gyeogam Yurok (격암유록, 格庵遗录, "Records Left by Gyeogam") is attributed to Nam Sa-go (1509–1571), a Joseon-era Korean scholar who styled himself "Gyeogam." He was renowned for his mastery of the I Ching, geomancy (feng shui), astronomy, divination, and physiognomy, and served as Professor of Astronomy at the Gwansanggam (Royal Observatory) in his later years. Legend has it that as a young man, he encountered a divine being on Mount Geumgang who imparted secret prophecies, which Nam Sa-go then recorded — thus creating the Gyeogam Yurok.
Written entirely in classical Chinese (Hanja), the text comprises 60 chapters in a cryptic prophetic style. It is believed to foretell major events on the Korean Peninsula from the Imjin War (1592) to the distant future, covering themes of dynastic rise and fall, foreign invasion, national division, and eventual reunification. The text shares thematic connections with another famous Korean prophecy, the Jeonggamnok (鄭鑑錄).
However, the authenticity of Gyeogam Yurok is highly disputed among scholars. The most widely circulated version was released by Lee Do-eun in 1977 and has been identified by multiple scholars as a forgery — the text contains modern Chinese coinages such as 'philosophy' (哲學), 'communism' (共産), and 'atom' (原子) that did not exist in Nam Sa-go's 16th-century era. Despite this, the text retains significant influence in Korean folk culture and has been cited and interpreted by various religious groups. This site presents selected chapters with verification analysis for reference.

Prophecy Verification Evaluating predictions against reality for expired time points
Song of Hidden Secrets — Imjin War
南师古: In the years of Dragon and Snake, beacon fires arise; from the south, Japanese pirates invade the realm. The people of all eight provinces suffer devastation; seven years of war engulf the mortal world.
Vernacular: In the Dragon and Snake years, war breaks out. Japanese invaders from the south assault the kingdom. The people across all eight provinces of Joseon suffer terribly, and seven years of warfare engulf the land.
The Imjin War (1592–1598) began in the year of Imjin (Dragon year). Toyotomi Hideyoshi's forces invaded Korea from the south. The war lasted approximately seven years and devastated all eight provinces of Joseon, closely matching the prophecy. However, scholars note the surviving text may have been composed after these events.
Song of Hidden Secrets — Manchu Invasion
南师古: Barbarian cavalry sweep south like a tide; Hanyang falls and the king flees. Besieged for months at Namhansanseong, forced to submit as vassal and pay tribute in agony.
Vernacular: Manchu cavalry surge southward like a tide, breaching Hanyang and forcing the king to flee. After months of siege at Namhansanseong fortress, the king is compelled to submit and pay tribute — a humiliation endured in anguish.
During the Manchu invasion of 1636–1637 (Byeongja Horan), Qing forces swept south and took Hanyang (modern Seoul). King Injo fled to Namhansanseong fortress, was besieged for 45 days, and surrendered, becoming a vassal of the Qing dynasty. The prophecy matches historical events closely, though scholars suspect the text was composed post-hoc.
Discourse on the Final Age — Dynastic Change
南师古: Five hundred years of dynastic foundation shall collapse; the Yi family's domain enters its twilight. Besieged by relentless foreign threats, the nation's strength is exhausted; as the old order crumbles, a new destiny takes shape.
Vernacular: The five-hundred-year-old dynastic foundation is about to crumble. The Joseon kingdom of the Yi (Lee) family enters its twilight years. Constant foreign threats drain the nation's strength, and as the old system collapses, a new fate is being forged.
The Joseon dynasty (1392–1897) lasted approximately 505 years before collapsing under pressure from foreign powers. It was reorganized as the Korean Empire in 1897 and annexed by Japan in 1910. The 'five hundred years of foundation' closely matches Joseon's actual duration.
Discourse on the Final Age — Foreign Rule
南师古: The sun rises in the east and invades our territory; for thirty-six years, darkness reigns. Iron hooves trample and shatter the mountains and rivers; the people's suffering cries out to heaven.
Vernacular: The nation of the rising sun from the east invades our land. For thirty-six years there is no light. Under the trampling of iron hooves, the mountains and rivers are shattered, and the people can only cry out their suffering to the heavens.
Japanese colonial rule over Korea lasted from 1910 to 1945, actually 35 years. The prophecy states 'thirty-six years,' off by one year (though counting from the 1909 Gisa Treaty yields exactly 36 years). 'Sun rises in the east' clearly refers to Japan. The description of suffering under colonial rule matches history, but the year count is slightly off.
Discourse on the Final Age — Liberation
南师古: The rooster crows thrice and dawn approaches; the old land is restored this very day. Amid cries of 'Manse,' the long night is banished; beneath the Taegukgi, all celebrate freedom.
Vernacular: The rooster crows three times as dawn approaches — liberation and the recovery of our homeland is at hand. Amid shouts of 'Manse' (ten thousand years), the long darkness is driven away, and under the Taegeuk flag, the nation celebrates its newfound freedom.
On August 15, 1945, Japan announced unconditional surrender and the Korean Peninsula was liberated. The 'Taegukgi' (Taegeuk flag) is the Korean national flag. 'Manse' (ten thousand years) echoes the rallying cry of the Korean independence movement (originating from the March 1st Movement of 1919). The description of liberation matches history precisely.
Song of Gap-Eul — North-South Division
南师古: One nation is suddenly split into south and north; kinfolk are separated like stars that never meet. An iron curtain descends upon the 38th parallel; flesh and blood are scattered, tears flow in a thousand streams.
Vernacular: A single nation is suddenly divided into south and north. The same people are kept apart like the stars Shen and Shang — destined never to meet. An iron curtain falls along the 38th parallel, and families are torn apart, their tears flowing endlessly.
After liberation in 1945, the Korean Peninsula was divided along the 38th parallel by US and Soviet occupation. In 1948, the Republic of Korea (South) and the DPRK (North) were established separately. The explicit mention of the '38th parallel,' national division, and family separation all match history. However, the concept of the '38th parallel' could not have existed in the 16th century — this is key evidence scholars cite questioning the text's authenticity.
Song of Gap-Eul — Korean War
南师古: In the year of Geng-Yin, war erupts; brothers under one roof turn weapons on each other — how urgent! North and south clash as blood runs like rivers; mountains and rivers are shattered, the people displaced.
Vernacular: In the Geng-Yin year, war breaks out suddenly. Brothers of the same household take up arms against one another with terrible urgency. North and south clash as blood flows like rivers, the land is shattered, and the people are displaced.
The Korean War broke out on June 25, 1950. The year 1950 is indeed Geng-Yin in the sexagenary cycle, matching the prophecy exactly. The war caused millions of casualties and devastated nearly the entire peninsula. 'Brothers turning weapons on each other' accurately describes the civil war nature of the conflict. Scholars note the Geng-Yin dating may have been added in the 1977 edition.
Discourse on the Final Age — Democratization
南师古: Though military might prevails, it too shall end; the people's voice rises like an unstoppable tide. Ten thousand candles illuminate the long night; the flower of freedom blooms across the land.
Vernacular: Though military authoritarianism is powerful, it will eventually end. The voice of the people surges like an unstoppable tide. Tens of thousands of candles light up the long dark night, and the flower of freedom blooms everywhere across the land.
South Korea achieved democratic transition after the June Democratic Struggle of 1987, ending decades of military authoritarian rule. 'Ten thousand candles' resonates with Korea's distinctive candlelight protest tradition (the 2016–2017 candlelight rallies led to presidential impeachment). From the 1980 Gwangju Uprising to the 1987 democratization, the Korean people's struggle matches the description of 'the people's voice rising like an unstoppable tide.'
Discourse on the Final Age — Economic Rise
南师古: The Han River flows day and night; the southern nation rises with ingenious resolve. From poverty and weakness, overnight a rich nation emerges; all nations gaze upon the towers of Hanseong.
Vernacular: The waters of the Han River flow ceaselessly day and night. The southern nation rises with determination and ingenuity. A once impoverished and weak nation transforms overnight into a prosperous power, and the world turns its gaze to the towers of Seoul.
South Korea achieved the 'Miracle on the Han River' from the 1960s onward, rising from one of the world's poorest nations to a developed economy. The 1988 Seoul Olympics marked Korea's arrival on the world stage. The mentions of 'Han River' and 'Hanseong' (Seoul) closely correspond to the geographic center of Korea's economic miracle. Per capita GDP rose from $79 in 1960 to thousands of dollars by the 1990s.
Discourse on the Final Age — Nuclear Threat
南师古: Atomic fire can destroy a nation; crisis on the peninsula hangs by a thread. When the north exhausts itself in militarism, ten thousand people pray to heaven for protection.
Vernacular: Atomic fire is powerful enough to destroy an entire nation. The crisis on the peninsula could erupt at any moment. When the north pursues militarism to exhaustion, the people pray to heaven for shelter and protection.
North Korea conducted its first nuclear test in 2006 and has since performed multiple tests, becoming a major security threat in Northeast Asia. 'Atomic fire' directly references nuclear weapons, and 'the north pursues militarism' describes North Korea's military-first policy. The Korean Peninsula nuclear crisis continues to this day. However, the word 'atom' did not exist in the 16th century — this is a key piece of evidence scholars cite in concluding the text is a forgery.
Discourse on the Final Age — Information Age
南师古: Within an inch, one communicates across ten thousand li; wireless sounds spread in all directions. All knowledge under heaven fits in the palm of one's hand — a sight never seen in a thousand ages.
Vernacular: Within the span of an inch, one can communicate across ten thousand li. Wireless sound transmissions reach in all directions. All the world's knowledge fits within one's palm — a spectacle never witnessed in all of recorded history.
The descriptions of 'communicating across ten thousand li within an inch' and 'all knowledge fits in the palm' can be interpreted as smartphones and mobile internet. South Korea has among the world's highest internet and smartphone adoption rates. The iPhone's 2007 debut marked the smartphone era. However, such descriptions are rather general, and the concept of 'wireless' did not exist in the 16th century — another piece of evidence scholars cite questioning the text's authenticity.
Discourse on the Final Age — Cultural Spread
南师古: Songs and dances of the East spread across the four seas; the Korean wind blows and blossoms in foreign lands. Young men and women everywhere compete to imitate; cultural export ushers in a new era.
Vernacular: Songs and dances from the East spread to all corners of the world. The Korean cultural wave blows across foreign shores and blossoms. Young people everywhere compete to emulate Korean culture, and cultural export ushers in a new era.
The Korean Wave (Hallyu) has swept the globe since the 2000s. K-pop (BTS, BLACKPINK, etc.), Korean dramas, and Korean films (Parasite won Best Picture at the 2020 Oscars) have had enormous global impact. In 2012, PSY's 'Gangnam Style' became the first YouTube video to surpass 1 billion views. 'Korean wind blossoms in foreign lands' matches the Hallyu phenomenon, though the wording is rather general.
Discourse on the Final Age — Natural Calamities
南师古: The four seasons lose their order and heaven and earth are transformed; heat and cold are reversed, and the people are uneasy. Floods and droughts alternate in succession; the earth groans and the skies darken.
Vernacular: The four seasons fall out of order as heaven and earth undergo great change. Heat and cold are reversed, causing unrest among the people. Floods and droughts arrive in alternation, the earth groans in agony, and the sky grows dark.
Global climate change has led to increasingly frequent extreme weather. South Korea has experienced abnormal heat waves, devastating floods (2022 Seoul floods, 2023 flooding in multiple regions), and alternating droughts. 'Seasons losing their order' partially matches the reality of climate anomalies. However, such general descriptions of natural disasters are extremely common in ancient prophecy texts and lack specific verifiable details.
Nam Sa-go's Secret — General Discourse
南师古: The Way of Heaven operates by constant principles; fortune and misfortune are all predetermined. Gyeogam received the secret on Mount Geumgang; within sixty chapters, heaven's mandate is concealed.
Vernacular: The workings of heaven follow fixed laws — fortune and calamity are predetermined. Nam Sa-go received divine secrets at Mount Geumgang, and within his sixty chapters lies the arrangement of heaven's mandate.
This is the opening outline of the entire text, serving as a general preface that introduces the work's framework through the legend of divine transmission at Mount Geumgang.
Song of Gap-Eul — Unification Prospect
南师古: Though division has lasted long, unity must eventually come; the cycle of heaven has its appointed time. North-south unification will herald a new era; a great peace in which all people rejoice.
Vernacular: Though the division has persisted for many years, reunification must eventually come — heaven's cycle has its predetermined time. The unification of North and South will open a new era, a great age of peace in which all people live in contentment.
Song of Gap-Eul — New Heaven and New Earth
南师古: A fine season to bid the old farewell and welcome the new — all things await the new heavenly destiny. On the day of rebuilding after calamity, the mortal world shall at last know a spring of peace.
Vernacular: It is a fine season to see out the old and welcome the new — all things have been waiting in hope for a new heavenly destiny to arrive. On the day of rebuilding after the great calamity, the human world will at last truly welcome a spring of peace.
