In the last episode, we met King Seong of Baekje. In 538 he moved the capital to Sabi and renamed the kingdom “Nambuyeo,” and in 551 he won back the old lands along the Han River—but in 553 Silla, which had fought alongside him, seized that land. The next year, during the Battle of Gwansan Fortress, the king was killed by a Silla ambush on a night road at Gucheon, and his eldest son, Chang, took the throne.

Chang (King Wideok) ruled Baekje for more than forty years. The kings who followed him, King Hye and King Beop, died one after the other, neither reigning even two years.

In 600, the son of King Beop took the throne.
He was the 30th king of Baekje: King Mu.

But the Samguk Yusa tells the story of this king’s childhood in an entirely different way.

The Yam-Digging Boy

The tale of Seodong, from the “King Mu” entry in the “Wonders” section of the Samguk Yusa

Long ago, by a pond south of the Baekje capital, there lived a woman on her own.

It is said that she came together with the dragon of that pond and bore a son.

The boy made his living by digging yams in the hills and selling them. People called him “Seodong,” meaning “the yam-digging boy.”

SeodongThe Yam-Digging Boy
WomanYou know Seonhwa, the third princess
of King Jinpyeong of Silla?
They say there’s no one more beautiful in the world!
SeodongPrincess Seonhwa…

Seodong shaved his head and went to Seorabeol, the capital of Silla. There he handed out yams to the neighborhood children.

Children of Seorabeol
ChildMister, more yams, please!
SeodongIn return, want to
learn a song?

The children ran through every alley, singing the song Seodong had taught them.

Princess Seonhwa
has married in secret,
and steals away by night
to hold her Seodong

善化公主主隱 他密只嫁良置古 薯童房乙 夜矣卯乙抱遣去如 — “Seodongyo,” Samguk Yusa

Children♪ Princess Seonhwa
has married in secret,
and steals away by night
to hold her Seodong~
Seorabeol residentWhat on earth is that song?!

The song spread through the whole capital, until at last it reached inside the palace.

King JinpyeongKing of Silla · The princess’s fatherPrincess SeonhwaKing Jinpyeong’s third princess
CourtiersThe song about the princess
has spread all over the capital!
King Jinpyeong……

The officials fiercely urged that the princess be banished far away. She was to be sent into exile in a distant place.

On the day she left, the queen gave her daughter a peck of pure gold.

QueenAt least take this with you…
Princess SeonhwaMother…

When she had almost reached her place of exile, a young man stepped out onto the road and bowed to her.

SeodongPrincess, allow me to escort you.

The princess did not know where he had come from, but somehow she trusted him and was glad. The two went on together.

Princess SeonhwaWhat is your name?
SeodongI am called Seodong.
Seodong…? From that song…!

As they traveled together, the two grew close. Only on hearing his name did the princess realize that the song had come true.

The two came to Baekje together. When the princess brought out the gold her mother had given her to talk over how they would live, Seodong burst out laughing.

SeodongHa ha ha!
What’s all this?
Princess SeonhwaIt’s gold!
Enough to live on for a hundred years.
Where I used to dig yams,
this stuff is piled up like dirt.
It’s the greatest treasure in the world! Why don’t we
send this gold to my parents’ palace?

The two heaped the gold up like a hill and went to see Master Jimyeong of Sajasa Temple on Mount Yonghwa.

Master JimyeongMonk of Sajasa Temple, Mount Yonghwa
Master JimyeongI can move it with my divine powers.
Bring the gold here.

When the princess wrote a letter to her parents and left it with the gold in front of Sajasa Temple,

the master used his divine powers to carry the gold to the Silla palace in a single night.

King JinpyeongIn a single night…
all this gold?
Seonhwa…

Astonished at this marvel, King Jinpyeong held Seodong in even higher regard, and it is said he often sent letters asking after him.

Through this, Seodong won people’s hearts, and at last he took the throne.

One day, on their way to Sajasa Temple, the king and queen came to the edge of a great pond below Mount Yonghwa.

QueenIt is my wish to build
a great temple here.

At that moment, a Maitreya triad rose from the middle of the pond.

With his divine powers, Master Jimyeong brought down a mountain in a single night and filled in the pond.

There, modeled on Maitreya’s three sermons, they built halls, pagodas and corridors in three places and named it “Mireuksa.” It is said that King Jinpyeong, too, sent craftsmen of every kind to help.

At the end of this tale, the Samguk Yusa added a note in small characters:

The Samguk Sagi calls him the son of King Beop,
but this tale calls him the son of a widow.
We cannot tell.

三國史云 是法王之子 而此傳之獨女之子 未詳 — Samguk Yusa

The Samguk Sagi records King Mu as the son of King Beop. His name was Jang (璋). He is said to have had an outstanding bearing, with the spirit and ambition of a hero.

King MuSon of King Beop · New king of Baekje
King MuI will make Baekje’s name
great once more.

In the eighth month of 602, King Mu sent out troops and besieged Silla’s Amaksan Fortress. But he was driven back by several thousand swift cavalry sent by King Jinpyeong.

Silla, far from backing down, built four new fortresses near the border—Sota, Oeseok, Cheonsan and Ongjam—threatening Baekje’s land.

The king was furious.

King MuJwapyeong Hae Su, take 40,000 foot and horse
and strike those four fortresses!
Hae SuJwapyeong (top minister) · Baekje general
Hae SuI will carry out your command!

When the fighting went badly, Hae Su fell back to a great pond west of Mount Cheonsan, hid his troops and waited.

Hae SuNow! Attack!

Mueun, the Silla general who had given chase, fell from his horse. But when Mueun’s son Gwisan and his friend Chuhang stood their ground and fought on, the Silla army rallied.

The Baekje army was badly defeated.

Hae Su barely escaped with his life and rode back alone.

Even after that, the fighting between the two kingdoms did not stop.

In 611 King Mu besieged Silla’s Gajam Fortress for a hundred days and took it, and in 616 he attacked Amak Fortress again. In 624 he seized six Silla fortresses.

In autumn 627, King Mu raised a great army to win back the land lost to Silla and made camp at Ungjin.

King MuThis time we will win back
the land we lost!

When King Jinpyeong heard the news and sent envoys to Tang to report the emergency, King Mu halted his army.

In the eighth month of that year, the king’s nephew Boksin went to Tang as an envoy. Emperor Taizong of Tang told Boksin that Baekje should make peace with Silla, and sent the king a letter as well.

BoksinKing Mu’s nephew
Emperor Taizong’s letter“Kim Jinpyeong, King of Silla, is Our vassal,
and your neighbor.”
“Forget old grudges, deepen your
neighborly ties, and stop fighting at once.”
King Mu……

King Mu sent envoys to give thanks. But the Samguk Sagi records: “Outwardly he claimed to obey, but inwardly the two still regarded each other as enemies.”

In the tale, King Jinpyeong of Silla and King Mu of Baekje were father-in-law and son-in-law.

In the records, the two kings
were at each other’s throats for nearly thirty years.

In the first month of 632, King Mu made his eldest son, Uija, crown prince. That same month, King Jinpyeong of Silla died.

In the second month of 634, Wangheungsa Temple was completed on the riverbank at Sabi. Its painted decorations were grand and splendid.

The king would often go to the temple by boat to burn incense.

In the third month, the king had a pond dug south of the palace. Water was brought from more than twenty li away, and willows were planted on its four banks.

King MuCould the mountain where
immortals dwell look like that?

In the middle of the water an island was built, modeled on Mount Fangzhang, where immortals were said to live.

In the third month of 636, the king led his officials to a feast at the northern inlet of the Sabi River. The strange rocks and flowers on both banks looked like a painting.

Drinking and in the highest spirits, the king played the geomungo and sang along to it, and his companions danced again and again. People called the place Daewangpo, “the Great King’s Inlet.”

King Mu♪ ♬ ♪

What song the king sang that day is not recorded anywhere.

The old songPrincess Seonhwa…

The 29th day of the 1st month, 639: Mireuksa Temple in Iksan. Sarira were enshrined in the stone pillar at the heart of the western stone pagoda, which was then being built.

Baekje queenKing Mu’s queen
QueenMay His Majesty the Great King’s years
stand as firm as the mountains…

Beside the gold sarira jar was placed a single gold plate engraved with writing.

In the third month of 641, King Mu died.

QueenMay His Majesty the Great King’s years stand as firm as the mountains…

Emperor Taizong of Tang mourned him at the Xuanwu Gate and posthumously honored him as Guanglu Daifu. His eldest son, Uija, took the throne.

The temple lived on long after Baekje fell, but at some point it fell into ruin. The western stone pagoda survived, half collapsed.

In 2001, to repair the pagoda, which seemed ready to collapse, workers began to dismantle it, taking down its stones one by one.

And then came January 14, 2009.

When the stone resting on the pillar at the center of the first story (the central pillar stone) was lifted, a square hole appeared in the top of the pillar.

ResearcherThere’s something…
inside the hole!
…It’s gold.

On the front and back of a palm-sized gold plate, some 190 characters had been engraved.

Researcher“Our Queen of Baekje, daughter
of Jwapyeong Sataek Jeokdeok…”
“…giving of pure wealth
to raise this temple…”
“…on the 29th day of the 1st month, gihae year,
reverently welcomed the sarira.”
The princess in the songIt is my wish to build a great temple here.
The queen in the gold plateGiving of pure wealth to raise this temple…

According to the gold plate, the queen who gave her wealth to raise the temple and enshrined sarira in this pagoda was the daughter of Sataek Jeokdeok, a Jwapyeong of Baekje.

The princess in the song came from Seorabeol in Silla. The queen in the gold plate was the daughter of a Baekje Jwapyeong.

Was the princess in the song just a made-up story,
or was she another queen
who came before the one in the gold plate?

The song that has come down through fourteen hundred years, and the gold plate that waited 1,370 years inside the pagoda, have yet to give us the answer.

History Notes

The scenes in this story are based on these records and sites.

  1. Samguk YusaSamguk Yusa · Kyujanggak, Seoul National University

    The Tale of Seodong in the Samguk Yusa

    The tale of Seodong appears in the “King Mu” entry of the “Wonders” section of the Samguk Yusa. Beneath the title, Iryeon noted, “An old text (gobon) calls him King Mugang, but Baekje had no King Mugang, so this is a mistake,” and at the end of the tale he added, “The Samguk Sagi says he was the son of King Beop, but this tale says he was the son of a widow, so we cannot tell.” Princess Seonhwa does not appear in the Samguk Sagi (the daughters of King Jinpyeong it mentions are his eldest, Deokman—that is, Queen Seondeok—and Lady Cheonmyeong, the mother of Kim Chun-chu). For this reason, some see the hero of the tale as King Dongseong or King Muryeong rather than King Mu, and others think several stories were woven together.

  2. Seodongyo — A Song Written in Hyangchal

    The song Seodong is said to have spread survives in hyangchal, a way of writing Korean by borrowing the sounds and meanings of Chinese characters: “善化公主主隱 / 他密只嫁良置古 / 薯童房乙 / 夜矣卯乙抱遣去如.” It is a hyangga of four lines (the four-line form), and the reading used in this episode (“Princess Seonhwa has married in secret, and steals away by night to hold her Seodong”) is today’s common interpretation, based on Yang Ju-dong’s reading. Following Yang, “薯童房乙” is usually read as “Matdung seobang” (“her man Matdung,” matdung being the boy who digs yams, that is, Seodong), but Kim Wan-jin reads it as “Seodong’s room.” Likewise, Yang reads “卯乙” as “mol(lae),” meaning “secretly,” while Kim takes it as a miswriting of “卵” (al, “egg”) and reads it as “the egg.” Readings vary from scholar to scholar, and there are several other interpretations as well.

    Father-in-Law in the Song, Rival in the Records

    In the Samguk Sagi, King Mu is a king who fought Silla relentlessly for 41 years. At the Battle of Amaksan Fortress (Mosan Fortress) in 602 (Episode 31), Jwapyeong Hae Su’s army of 40,000 was badly defeated, but in 611 King Mu took Gajam Fortress in a hundred days, and in 624 he seized six fortresses. When he massed troops at Ungjin in 627, King Jinpyeong reported the emergency to Tang, and Emperor Taizong of Tang sent a letter telling him to “forget past grudges and stop fighting.” The Samguk Sagi records that King Mu “pretended to obey outwardly, but inwardly still regarded Silla as an enemy.”

    Wangheungsa Temple · Gungnamji Pond · Daewangpo

    The Samguk Sagi records that in the second month of 634 Wangheungsa Temple, standing by the water, was completed, and the king often went there by boat to burn incense; and that in the third month he had a pond dug south of the palace, bringing in water from more than 20 li away and adorning it with willows and an island of the immortals (Mount Fangzhang). Today’s Gungnamji Pond in Buyeo is a pond restored in the 1960s on the basis of this record. The place where King Mu played the geomungo and sang in the third month of 636 was called “Daewangpo.” Meanwhile, the Samguk Sagi says that King Beop began building Wangheungsa in 600, but a sarira container found in 2007 at the site of the temple’s wooden pagoda bears the inscription: “On the 15th day of the 2nd month of the jeongyu year (577), Chang, King of Baekje (King Wideok), erected a stupa (刹) for his dead prince.” For this reason, some think the pagoda went up first, under King Wideok, and others date the founding of the temple itself to his reign.

    Mireuksa Temple and Its Western Stone Pagoda

    When the site of Mireuksa Temple below Mount Mireuk (formerly Mount Yonghwa) in Iksan was excavated from 1980 to 1994, it turned out to have a “three-courtyard” layout, with a wooden pagoda in the middle and stone pagodas to the east and west, each forming its own compound—just as the Samguk Yusa says: “they built halls, pagodas and corridors in three places.” The western stone pagoda is the oldest and largest of Korea’s surviving stone pagodas (a National Treasure); it is thought to have had nine stories, but only six remain. In 1915 its collapsed side had been patched with cement; from 2001 the pagoda was dismantled and rebuilt, and in 2019 nearly twenty years of repairs came to an end. In 2015 it became a World Heritage Site as part of the “Baekje Historic Areas.”

  6. Gold sarira enshrinement record from the stone pagoda at the Mireuksa Temple siteGold sarira enshrinement record · Iksan National Museum

    A Single Gold Plate — Sarira Enshrinement Record

    On January 14, 2009, a gold sarira jar, a gold plate (15.3 centimeters wide and 10.3 centimeters high) and more than 500 offerings were found in the sarira niche (about 25 centimeters on each side) in the top of the stone pillar at the center of the western pagoda’s first story. The plate was engraved with the words that “our Queen of Baekje, daughter of Jwapyeong Sataek Jeokdeok,” gave of her wealth to build the temple, and on the 29th day of the 1st month of the gihae year (639) reverently welcomed the sarira and prayed for the Great King’s long life. This gave rise to several views at once: that the tale of Princess Seonhwa is a legend made up later; that King Mu had more than one queen, so Princess Seonhwa may have been an earlier one; and that the plate tells the story of the western pagoda alone, one of the temple’s three compounds. No conclusion has yet been reached either way.

    Iksan — Wanggung-ri, the Twin Tombs, and What We Imagined

    At Wanggung-ri in Iksan lies a 7th-century palace site enclosed by walls about 240 meters from east to west and about 490 meters from north to south, complete with gardens, workshops and even toilets, which has led to the view that King Mu used Iksan as a second capital (the capital-relocation theory, the secondary-capital theory and others). The “Treatise on Geography” of the Goryeosa calls the Twin Tombs (Ssangneung) of Iksan “the tombs of King Mugang of Later Joseon and his queen,” noting that common people called them “Maltong Daewangneung” and also said they were the tomb of King Mu of Baekje (whose childhood name was Seodong). In 2018, bones from the Great King’s Tomb (Daewangneung) were identified as those of an elderly man who died around 620–659, strengthening the view that it is King Mu’s tomb. In this episode, the people in the shadow plays and their words, the appearance of Wangheungsa Temple, Daewangpo and Mireuksa Temple, the queen enshrining the sarira, and the researchers of 2009 are all imagined.
