Sun Wukong’s Four Mighty Commanders

The Monkey King’s “Four Mighty Commanders” (Si Jianjiang, 四健將) (figs. 1 & 2) are minor characters appearing in chapters one, three to six, and 28 of Journey to the West (Xiyouji西遊記). They are presented as two elderly gibbons and two elderly horse-monkeys (i.e. macaques) who serve their monarch as advisors and makeshift tutors on spiritual and military matters. In fact, one of them is responsible for setting Wukong on his path towards immortality. They are later given high military rank and charged with training and governing Wukong’s monkey army. An outside observer may question the commanders’ ability to lead troops in battle since they are defeated in nearly every single skirmish. But it should be remembered that, while technically immortal, they can still be killed and only have access to mere earthly weapons. Yet, they choose to face celestial soldiers who wield divine weapons and have millennia of combat experience. This speaks to their great bravery.

Here, I have gathered all references to these characters that I know of. I’ve also included a section on the possible homophonic origins of their names, as well as a section describing their immortality.

This article was prompted by a question put to me on tumblr. Searching the site for “beng ba” and “ma liu” results in a number of posts with fan art and fiction, so this survey has merit. Hopefully it will benefit fans of the novel and/or those who wish to insert these characters into their Lego Monkey Kid-inspired media.

Chapter 1

Note: I have changed some of Yu’s (Wu & Yu, 2012) translations of primate names for more accuracy.

[The Stone Monkey becomes the king of the primates through a test of bravery: leaping through a waterfall and discovering a long-forgotten immortal’s cave.]

The Handsome Monkey King thus led a flock of gibbons [yuanhou, 猿猴], macaques [mihou, 獼猴], and horse-monkeys [mahou, 馬猴], some of whom were appointed by him as his officers and ministers (based on Wu & Yu, 2012, vol. 1, p. 106).

[After 300-something years of ruling the Mountain of Flowers and Fruit, the Monkey King comes to realize that he too will someday die.]

From among the ranks a long-armed gibbon [tongbei yuanhou, 通背猿猴; lit: “(arms)-through-the back-gibbon”] [1] suddenly leaped forth and cried aloud, “If the Great King is so farsighted, it may well indicate the sprouting of his religious inclination. There are, among the five major divisions of all living creatures, only three species that are not subject to Yama, King of the Underworld.” The Monkey King said, “Do you know who they are?” The monkey said, “They are the Buddhas, the immortals, and the holy sages; these three alone can avoid the Wheel of Transmigration as well as the process of birth and destruction, and live as long as Heaven and Earth, the mountains and the streams.” “Where do they live?” asked the Monkey King. The monkey said, “They do not live beyond the world of the Jambudvipa, for they dwell within ancient caves on immortal mountains.” When the Monkey King heard this, he was filled with delight, saying, “Tomorrow I shall take leave of you all and go down the mountain. Even if I have to wander with the clouds to the comers of the sea or journey to the distant edges of Heaven, I intend to find these three kinds of people. I will learn from them how to be young forever and escape the calamity inflicted by King Yama” (based on Wu & Yu, 2012, vol. 1, p. 107).
Chapter 3
[After returning from abroad, the Monkey King wishes to train his children in how to defend themselves with weapons since they had previously been plagued by the Demon King of Havoc.]

As they were speaking, four older monkeys came forward, two horse-monkeys with red buttocks [chikao mahou, 赤尻馬猴] and two long-armed gibbons. Coming to the front, they said, “Great King, to be furnished with sharp-edged weapons is a very simple matter.” “How is it simple?” asked Wukong. The four monkeys replied, “East of our mountain, across two hundred miles of water, is the boundary of the Aolai Country. In that country there is a king who has numberless men and soldiers in his city, and there are bound to be all kinds of gold, silver, copper, and iron works there. If the great king goes there, he can either buy weapons or have them made (based on Wu & Yu, 2012, vol. 1, p. 131).

[Wukong frets over not having a divine weapon that fits his taste.]

The four elder monkeys came forward and memorialized, “The great king is a divine sage, and therefore it is not fit for him to use an earthly weapon. We do not know, however, whether the great king is able to take a journey through water?” “Since I have known the Way,” said Wukong, “I have the ability of seventy-two transformations. The cloud somersault has unlimited power. I am familiar with the magic of body concealment and the magic of displacement. I can find my way to Heaven or I can enter the Earth. I can walk past the sun and the moon without casting a shadow, and I can penetrate stone and metal without hindrance. Water cannot drown me, nor fire burn me. Is there any place I can’t go to?” “It’s a good thing that the great king possesses such powers,” said the four monkeys, “for the water below this sheet iron bridge of ours flows directly into the Dragon Palace of the Eastern Ocean. If you are willing to go down there, Great King, you will find the old Dragon King, from whom you may request some kind of weapon. Won’t that be to your liking?” Hearing this, Wukong said with delight, “Let me make the trip!” (Wu & Yu, 2012, vol. 1, p. 133).

[He returns from the Dragon Kingdom with his magic iron staff.]

The Monkey King made the four old monkeys mighty commanders of his troops by appointing the two horse-monkeys with red buttocks as marshals Ma and Liu [Ma, Liu er yuanshuai, 馬、流二元帥], and the two long-armed gibbon as generals Beng and Ba [Beng, Ba er jiangjun, 崩、芭二將軍]. The four mighty commanders, moreover, were entrusted with all matters concerning fortification, pitching camps, reward, and punishment (based on Wu & Yu, 2012, vol. 1, p. 138).

[The Monkey King becomes sworn brothers with six other animal demon kings.]

One day, the four mighty commanders had been told to prepare a great banquet in their own cave, and the six kings were invited to the feast. They killed cows and slaughtered horses; they sacrificed to Heaven and Earth. The various imps were ordered to dance and sing, and they all drank until they were thoroughly drunk. After sending the six kings off, Wukong also rewarded the leaders great and small with gifts. Reclining in the shade of pine trees near the sheet iron bridge, he fell asleep in a moment. The four mighty commanders led the crowd to form a protective circle around him, not daring to raise their voices (based on Wu & Yu, 2012, vol. 1, p. 139).
[Wukong’s soul is taken to the underworld because he is fated to die at 342 year old. However, he inks out his name, as well as those of all other monkeys, from the ledgers of hell and then fights his way out of the world of darkness.]

While our Monkey King was fighting his way out of the city, he was suddenly caught in a clump of grass and stumbled. Waking up with a start, he realized that it was all a dream. As he was stretching himself, he heard the four mighty commanders and the various monkeys crying with a loud voice, “Great King! How much wine did you imbibe? You’ve slept all night long. Aren’t you awake yet?” “Sleeping is nothing to get excited about,” said Wukong, “but I dreamed that two men came to arrest me, and I didn’t perceive their intention until they brought me to the outskirts of the Region of Darkness. Showing my power, I protested right up to the Palace of Darkness and argued with the Ten Kings. I went through our ledger of births and deaths and crossed out all our names. Those fellows have no hold over us now.” The various monkeys all kowtowed to express their gratitude. From that time onward there were many mountain monkeys who did not grow old, for their names were not registered in the Underworld. When the Handsome Monkey King finished his account of what had happened, the four mighty commanders reported the story to the demon kings of various caves, who all came to tender their congratulations (Wu & Yu, 2012, vol. 1, p. 141).

[Monkey is invited to heaven to be the keeper of the heavenly horses. This is a plan to keep his unruly adventures in check.]

He then called the four mighty commanders together for this admonition: “Be diligent in teaching and drilling the young ones. Let me go up to Heaven to take a look and to see whether I can have you all brought up there too to live with me.” The four mighty commanders indicated their obedience (Wu & Yu, 2012, vol. 1, p. 144).
Chapter 4
[He leaves heaven in rebellion when he learns that his post is the lowest in the celestial bureaucracy.]

ln a moment, he lowered the direction of his cloud and returned to the Flower-Fruit Mountain. The four mighty commanders were seen drilling troops with the Monster Kings of various caves. “Little ones,” this Monkey King cried in a loud voice, “old Monkey has returned!” (Wu & Yu, 2012, vol. 1, p. 150).

[A demon suggests a rebellious title for Wukong.]

“Make me a banner immediately,” he ordered the four mighty commanders, “and inscribe on it in large letters, ‘The Great Sage, Equal to Heaven.’ Erect a pole to hang it on” (Wu & Yu, 2012, vol. 1, p. 151).
Chapter 5
[He is granted the empty title of “Great Sage Equaling Heaven” and charged with guarding the immortal peach groves. However, he eats most of the ripe fruit, and then he wrecks a long-awaited banquet just because he isn’t invited. He finally flees to earth.]

Lowering the direction of his cloud, he returned to the Flower-Fruit Mountain. There he was greeted by flashing banners and shining spears, for the four mighty commanders and the monster kings of seventy-two caves were engaging in a military exercise. “Little ones,” the Great Sage called out loudly, “I have returned!” The monsters dropped their weapons and knelt down, saying, “Great Sage! What laxity of mind! You left us for so long, and did not even once visit us to see how we were doing.” “It’s not that long!” said the Great Sage. “It’s not that long!” They walked as they talked, and went deep inside the cave dwelling. After sweeping the place clean and preparing a place for him to rest, and after kowtowing and doing homage, the four mighty commanders said, “The Great Sage has been living for over a century in Heaven. May we ask what appointment he actually received?”

“I recall that it’s been but half a year,” said the Great Sage, laughing. “How can you talk of a century?” “One day in Heaven,” said the commanders, “is equal to one year on Earth” (Wu & Yu, 2012, vol. 1, p. 166).

[…]
[Wukong describes leaving heaven after trashing the banquet and eating Laozi’s elixir pills.]

The various monsters were delighted by these words, and they prepared a banquet of fruits and wine to welcome him. A stone bowl was filled with coconut wine and presented to the Great Sage, who took a mouthful and then exclaimed with a grimace, “It tastes awful! Just awful!” “The Great Sage,” said Beng and Ba, the two commanders, “has grown accustomed to tasting divine wine and food in Heaven. Small wonder that coconut wine now seems hardly delectable. But the proverb says, “Tasty or not, it’s water from home!” (Wu & Yu, 2012, vol. 1, p. 167).

[Heaven calls up forces to end his hijinks. The first to challenge him are the Nine Luminaries, anthropomorphic deities of the planets, moon, and sun.]

Hastily the little monsters reported inside, “Great Sage, disaster! Disaster! Outside there are nine savage deities who claim that they are sent from the Region Above to subdue the Great Sage.” Our Great Sage was just sharing the Heavenly wine with the four mighty commanders and the monster kings of seventy-two caves. Hearing this announcement, he said in a most nonchalant manner,

“If you have wine today, get drunk today;
Mind not the troubles in front of your door!”

Hardly had he finished speaking when still another flock of imps arrived to report, “Father, those nine savage gods have broken down the door, and are about to fight their way in!”

These reckless, witless gods!” said the Great Sage angrily. “They really have no manners! I was not about to quarrel with them. Why are they abusing me to my face?” He gave the order for the One-Horn Demon King to lead the monster kings of seventy-two caves to battle, adding that old Monkey and the four mighty commanders would follow in the rear. The Demon King swiftly led his troops of ogres to go out to fight, but they were ambushed by the Nine Luminaries and pinned down right at the head of the sheet iron bridge (Wu & Yu, 2012, vol. 1, pp. 170-171).

[…]
[The Monkey King singlehandedly defeats the Nine Luminaries.]

Devaraja Li then ordered the Four Great Devarajas and the Twenty-Eight Constellations to go out together to do battle. Without displaying the slightest panic, the Great Sage also ordered the One-Horn Demon King, the monster kings of seventy-two caves, and the four mighty commanders to range themselves in battle formation in front of the cave (Wu & Yu, 2012, vol. 1, p. 171).

[…]

Beginning with the battle formation at dawn, they fought until the sun sank down behind the western hills. The One-Horn Demon King and the monster kings of seventy-two caves were all taken captive by the forces of Heaven. Those who escaped were the four mighty commanders and the troop of monkeys, who hid themselves deep inside the Water-Curtain Cave. With his single rod, the Great Sage withstood in midair the Four Great Devarajas, Li the Pagoda Bearer, and Prince Nata, and battled with them for a long time. When he saw that evening was approaching, the Great Sage plucked a handful of hairs, threw them into his mouth, and chewed them to pieces. He spat them out, crying, “Change!” They changed at once into many thousands of Great Sages, each employing a golden-hooped rod! They beat back Prince Nata and defeated the Five Devarajas.

In triumph the Great Sage collected back his hairs and hurried back to his cave. Soon, at the head of the sheet iron bridge, he was met by the four mighty commanders leading the rest of the monkeys. As they kowtowed to receive him they cried three times, sobbing aloud, and then they laughed three times, hee-heeing and ho-hoing. The Great Sage said, “Why do you all laugh and cry when you see me?” “When we fought with the Deva Kings this morning,” said the four mighty commanders, “the monster kings of seventy-two caves and the One-Horn Demon King were all taken captive by the gods. We were the only ones who managed to escape alive, and that is why we cried. Now we see that the Great Sage has returned unharmed and triumphant, and so we laugh as well.”

“Victory and defeat,” said the Great Sage, “are the common experiences of a soldier. The ancient proverb says,

You may kill ten thousand of your enemies,
But you will lose three thousand of your allies!

Moreover, those chieftains who have been captured are tigers and leopards, wolves and insects, badgers and foxes, and the like. Not a single member of our own kind has been hurt. Why then should we be disconsolate? Although our adversaries have been beaten back by my magic of body division, they are still encamped at the foot of our mountain. Let us be most vigilant, therefore, in our defense. Have a good meal, rest well, and conserve your energy. When morning comes, watch me perform a great magic and capture some of these generals from Heaven, so that our comrades may be avenged.” The four mighty commanders drank a few bowls of coconut wine with the host of monkeys and went to sleep peacefully. We shall speak no more of them (Wu & Yu, 2012, vol. 1, pp. 172-173).
Chapter 6
[Erlang is called in to capture Wukong.]

The Immortal Master fought the Great Sage for more than three hundred rounds, but the result still could not be determined. The Immortal Master, therefore, summoned all his magical powers; with a shake, he made his body a hundred thousand feet tall. Holding with both hands the divine lance of three points and two blades like the peaks that cap the Hua Mountain, this green-faced, saber-toothed figure with scarlet hair aimed a violent blow at the head of the Great Sage. But the Great Sage also exerted his magical power and changed himself into a figure having the features and height of Erlang. He wielded a compliant golden-hooped rod that resembled the Heaven-supporting pillar on top of Mount Kunlun to oppose the god Erlang. This vision so terrified the marshals, Ma and Liu, that they could no longer wave the flags, and so appalled the generals, Beng and Ba, that they could use neither scimitar nor sword. On the side of Erlang, the Brothers Kang, Zhang, Yao, Li, Guo Shen, and Zhi Jian gave the order to the plant-headed deities to let loose the falcons and dogs and to advance upon those monkeys in front of the Water-Curtain Cave with mounted arrows and drawn bows. The charge, alas,

Dispersed the four mighty commanders of monkey imps
And captured two or three thousand numinous fiends!

Those monkeys dropped their spears and abandoned their armor, forsook their swords, and threw away their lances. They scattered in all directions running, screaming, scuttling up the mountain, or scrambling back to the cave. It was as if a cat at night had stolen upon resting birds: they darted up as stars to fill the sky. The Brothers thus gained a complete victory, of which we shall speak no further (Wu & Yu, 2012, vol. 1, pp. 181-182).
Chapter 28
[Monkey returns to the Mountain of Flowers and Fruit after being kicked out of the pilgrimage. He discovers that the remainder of his children are plagued by human hunters that eat or force them to perform tricks.]

When the Great Sage heard these words, he became terribly angry. “Who is in charge in the cave now?” he asked. “We still have Ma and Liu, the two marshals,” said the little fiends, “[B]eng and Ba, the two generals, they are in charge.” “Report to them at once,” said the Great Sage, “and say that I’ve returned.” Those little fiends dashed inside the cave and cried, “Father Great Sage has come home!” When Ma, Liu, [B]eng, and Ba heard the report, they rushed out of the door to kowtow and to receive him inside the cave. The Great Sage took a seat in the middle as the various fiends all lined up before him to pay homage. “Father Great Sage,” they said, “we heard recently that you had regained your life so that you could protect the Tang Monk on his journey to the Western Heaven to acquire scriptures. Why are you not heading toward the West? Why do you come back to this mountain?”

“Little ones,” said the Great Sage, “you have no idea that the Tang Monk is wholly ignorant of who is worthy and who is foolish. For his sake, I caught fiends and overcame demons throughout the journey, using all my abilities. Several times I slew a monster, but, accusing me of doing evil and violence, he disowned me as his disciple and banished me back here. He even wrote me a formal letter of banishment as proof that he would never want to use me again.” Clapping their hands and roaring with laughter, the monkeys said, “Lucky! Lucky! What do you want to be a monk for? Come home and you can lead us to have a few years’ fun. Quick! Let’s bring out the coconut wine for the reception of Father.” “Let’s not drink wine just yet,” said the Great Sage. “Let me ask you, how often do those hunters come to our mountain?” “Great Sage,” said Ma and Liu, “there’s no telling of time. They are here every day to make trouble.” The Great Sage asked, “Why aren’t they here today?” Ma and Liu replied, “Just wait and you’ll see them come” (Wu & Yu, 2012, vol. 2, pp. 31-32).

II. Meaning of Names

This Chinese article suggests a naturalistic explanation for these odd-sounding names:

Beng-Ba [崩芭] should be a homophone of “bengba” [蹦巴], that is, bengda [蹦躂], which means that the monkey jumps up and down all day without a moment’s peace. Therefore, it became an alternative name for monkeys. Ma-Liu [馬流] is a homophone for “maliu” [麻溜], which means the monkey moves with speed and agility.

… 崩芭應為「蹦巴」諧音,即蹦躂,意指猴子整日蹦蹦跳跳,伏低竄高,沒個安靜時候,所以成了猴子別稱。馬流即「麻溜」諧音,意即猴子動作麻溜,敏捷迅速。

III. Immortality

I mentioned in the introduction that the Four Mighty Commanders are technically immortal. This is the result of Wukong inking out the names of all monkeys from the ledgers of hell in chapter three (fig. 2). Wukong explains:

I went through our ledger of births and deaths [shengsi buzi, 生死簿子] and crossed out all our names. Those fellows have no hold over us now.” The various monkeys all kowtowed to express their gratitude. From that time onward there were many mountain monkeys [shanhou, 山猴] who did not grow old, for their names were not registered in the Underworld (Wu & Yu, 2012, vol. 1, p. 141).

Their divine longevity is exhibited when they reappear in chapter 28, sometime after Wukong is released from his 600-plus year imprisonment under Five Elements Mountain.

This same chapter also reveals that they are still capable of dying if fatally wounded. The rank and file monkeys lament their fate at the hands of human hunters:

Those of us who were shot by arrows, pierced by spears, or clubbed to death they took away for food to be served with rice. The dead monkeys would be skinned and boned, cooked with sauce and steamed with vinegar, fried with oil, and sauteed with salt (Wu & Yu, 2012, vol. 2, p. 31).

Note:

1) This term refers to the belief that the long, agile arms of the gibbon were somehow connected (i.e. tongbi, 通臂), passing through the back (i.e. tongbei, 通背) (Gulik, 1967, p. 92-93).

A Study of the Four Celestial Primates from Journey to the West

Last updated: 01-04-2024

Sun Wukong faces his evil double, the Six-Eared Macaque, in chapters 56 to 58 of Journey to the West (Xiyouji, 西遊記, 1592, JTTW hereafter). After the twin Mind Monkeys battle their way to the Western Paradise, the Buddha reveals the doppelganger’s true identity, noting that he and Monkey are two of four celestial primates (hunshi sihou, 混世四猴, lit: “four monkeys of havoc”) with amazing abilities:

“The first,” said Tathagata, “is the Stone-Monkey of Numinous Wisdom [Lingming shihou, 靈明石猴], [1] who

Knows transformations,
Recognizes the seasons,
Discerns the advantages of earth,
And is able to alter the course of planets and stars.

The second is the Red-Buttocked Horse-Monkey [Chikao mahou, 赤尻馬猴], who

Has knowledge of yin and yang,
Understands human affairs,
Is adept in its daily life
And able to avoid death and lengthen its life.

The third is the Long-Armed Gibbon [Tongbi yuanhou, 通臂猿猴], who can

Seize the sun and the moon,
Shorten a thousand mountains,
Distinguish the auspicious from the inauspicious,
And manipulate planets and stars.

The fourth is the Six-Eared Macaque [Liu’er mihou, 六耳獼猴] who has

A sensitive ear,
Discernment of fundamental principles,
Knowledge of past and future,
And comprehension of all things.

These four kinds of monkeys are not classified in the ten categories [of life], nor are they contained in the names between Heaven and Earth. As I see the matter, that specious Wukong must be a six-eared macaque, for even if this monkey stands in one place, he can possess the knowledge of events a thousand miles away and whatever a man may say in that distance” (based on Wu & Yu, 2012, vol. 3, p. 115).

如來道:「第一是靈明石猴,通變化,識天時,知地利,移星換斗;第二是赤尻馬猴,曉陰陽,會人事,善出入,避死延生;第三是通臂猿猴,拿日月,縮千山,辨休咎,乾坤摩弄;第四是六耳獼猴,善聆音,能察理,知前後,萬物皆明。此四猴者,不入十類之種,不達兩間之名。我觀假悟空乃六耳獼猴也。此猴若立一處,能知千里外之事;凡人說話,亦能知之。

In this article, I would like to explore all mentions of these magical creatures in the novel. I will focus more on the second and third primates as I’ve already written extensively about the first and fourth kind.

1. Stone-Monkey

There isn’t much to write about the “Stone-Monkey of Numinous Wisdom” (Lingming shihou, 靈明石猴) (fig. 1) as it’s clearly Sun Wukong. The term lingming (靈明) can also be translated as “Numinous Luminosity.” Both refer to spiritual wisdom. This explains why Sun Wukong attains so much power after only three years of spiritual cultivation.

Fig. 1 – A poster of the Stone-Monkey of Luminous Wisdom from the film Four Monkeys. The name has since been changed. See update 02-20-22 below.

2. Horse-Monkey and Gibbon

I’m grouping these two together because they share a close association in JTTW. The Chinese term for “Red-Buttocked Horse-Monkey” (Chikao mahou, 赤尻馬猴) (fig. 2) appears three times in the novel, while “Horse-Monkey” (馬猴, Mahou) only appears once (see here). [2] The term “(Arms)-Through-the-Back Gibbon” (Tongbei yuanhou, 通背猿猴) appears three times, while the interchangeable term “Connected Arms Gibbon” (Tongbi yuanhou, 通臂猿猴) appears once (see here and here) (fig. 3). Both essentially mean “Long-Armed Gibbon.” (This refers to the belief that the small ape’s long, agile arms were somehow connected (i.e. tongbi, 通臂), passing through the back (i.e. tongbei, 通背) (Gulik, 1967, p. 92-93).) The term “ape” or “gibbon” (yuanhou, 猿猴) appears 16 times (see here), and it’s even used to refer to Monkey. For example, a poem in chapter seven calls him “The Great Sage, Equal to Heaven, a monstrous ape” (Qitian dasheng yuanhou guai, 齊天大聖猿猴怪) (Wu & Yu, 2012, vol. 1, p. 191). Horse-monkeys and gibbons are surprisingly listed among the Monkey King’s retinue:

The Handsome Monkey King thus led a flock of gibbons [猿猴], macaques [mihou, 獼猴], and horse-monkeys [馬猴], some of whom were appointed by him as his officers and ministers (based Wu & Yu, 2012, vol. 1, p. 106).

美猴王領一群猿猴、獼猴、馬猴等,分派了君臣佐使

It’s actually a long-armed gibbon who reveals the truth of spiritual beings escaping the hand of death, setting Monkey on his quest for immortality:

From among the ranks a long-armed gibbon [tongbei yuanhou, 通背猿猴] suddenly leaped forth and cried aloud, “If the Great King is so farsighted, it may well indicate the sprouting of his religious inclination. There are, among the five major divisions of all living creatures, only three species that are not subject to Yama, King of the Underworld.” The Monkey King said, “Do you know who they are?” The monkey said, “They are the Buddhas, the immortals, and the holy sages; these three alone can avoid the Wheel of Transmigration as well as the process of birth and destruction, and live as long as Heaven and Earth, the mountains and the streams.” “Where do they live?” asked the Monkey King. The monkey said, “They do not live beyond the world of the Jambudvipa, for they dwell within ancient caves on immortal mountains.” When the Monkey King heard this, he was filled with delight, saying, “Tomorrow I shall take leave of you all and go down the mountain. Even if I have to wander with the clouds to the comers of the sea or journey to the distant edges of Heaven, I intend to find these three kinds of people. I will learn from them how to be young forever and escape the calamity inflicted by King Yama” (based on Wu & Yu, 2012, vol. 1, p. 131).

只見那班部中,忽跳出一個通背猿猴,厲聲高叫道:「大王若是這般遠慮,真所謂道心開發也。如今五蟲之內,惟有三等名色不伏閻王老子所管。」猴王道:「你知那三等人?」猿猴道:「乃是佛與仙與神聖三者,躲過輪迴,不生不滅,與天地山川齊壽。」猴王道:「此三者居於何所?」猿猴道:「他只在閻浮世界之中,古洞仙山之內。」猴王聞之,滿心歡喜道:「我明日就辭汝等下山,雲遊海角,遠涉天涯,務必訪此三者,學一個不老長生,常躲過閻君之難。」

Apart from this, chapter two casts both the long-armed gibbons and red-buttocked horse-monkeys as knowledgeable elders:

As they were speaking, four older monkeys came forward, two horse-monkeys with red buttocks [chikao mahou, 赤尻馬猴] and long-armed gibbons [tongbei yuanhou, 通背猿猴]. Coming to the front, they said, “Great King, to be furnished with sharp-edged weapons is a very simple matter:’ “How is it simple?” asked Wukong. The four monkeys replied, “East of our mountain, across two hundred miles of water, is the boundary of the Aolai Country. In that country there is a king who has numberless men and soldiers in his city, and there are bound to be all kinds of gold, silver, copper, and iron works there. If the great king goes there, he can either buy weapons or have them made (based on Wu & Yu, 2012, vol. 1, p. 131).

正說間,轉上四個老猴,兩個是赤尻馬猴,兩個是通背猿猴,走在面前道:「大王,若要治鋒利器械,甚是容易。」悟空道:「怎見容易?」四猴道:「我們這山向東去,有二百里水面,那廂乃傲來國界。那國界中有一王位,滿城中軍民無數,必有金銀銅鐵等匠作。大王若去那裡,或買或造些兵器

Later in the chapter, they are appointed officers:

The Monkey King made the four old monkeys mighty commanders of his troops by appointing the two horse-monkeys with red buttocks [赤尻馬猴] as Marshals Ma [馬] and Liu [流], and the two long-armed gibbons as Generals Beng [崩] and Ba [芭] (based on Wu & Yu, 2012, vol. 1, p. 138).

猴王將那四個老猴封為健將,將兩個赤尻馬猴喚做馬、流二元帥,兩個通背猿猴喚做崩、芭二將軍

These primates are mentioned in a few other chapters (see here and here).

2.1. True Identity?

Anthony C. Yu (Wu & Yu, 2012) calls the horse-monkey a “baboon” (vol. 3, p. 115, for example), likely based on the common image of the primate having a red bottom. And while searching “馬猴” does pull up images and articles about the Mandrill, a large, colorful cousin of the baboon (example), I can’t find any reliable historical sources linking the animal with the term. Having said that, this book associates it with the ancient Chinese practice of putting monkeys in horse stables (majiu husun, 馬廄猢猻) to ward off equine sicknesses, making it a “horse’s monkey.” This naturally has connections to Sun Wukong’s time as the Bimawen, or keeper of the heavenly horses. This is the most convincing explanation for the horse-monkey that I’ve seen, but I’ll make sure to update the article if any other plausible reasons arise. As for the red bottom, this is likely the sexual swelling of females. I’ll spare you a picture; just imagine a bright pink pumpkin that’s about to explode.

The gibbon and macaque are real world animals. For more information on Chinese views of the gibbon, please see this archived book.

3. Six-Eared Macaque

The Chinese term for macaque, mihou (獼猴), appears a total of 13 times (see here). Two refer to monkeys in general (here and here), while three refer to the Macaque King (Mihou wang獼猴王) (see here), Wukong’s sworn brother. A total of eight refer to the Six-Eared Macaque (Liu’er mihou, 六耳獼猴) (see here, here, and here).

I’ve already written an article exploring the literary and religious origins of Six Ears. The novel presents him as a negative manifestation of Sun Wukong’s mind. I suggest that their battle is an allegory for the internal struggle between the true and illusionary aspects of Monkey’s psyche. Another scholar has also posited that Six Ears appears earlier in the novel as the Macaque King.

4. The Same or Similar?

Let’s compare the Four Celestial Primates with the apes and monkeys from the Great Sage’s mountain home:

Four Celestial Primates

  1. Stone-Monkey of Luminous Wisdom (Lingming shihou) (i.e. Sun Wukong)
  2. Red-Buttocked Horse-Monkey (Chikao mahou)
  3. Long-Armed Gibbon (Tongbi yuanhou)
  4. Six-Eared Macaque (Liu’er mihou). 

Flower-Fruit Mountain

  1. Stone-Monkey (i.e. Sun Wukong)
  2. Red-Buttocked Horse-Monkeys (Chikao mahou)
  3. Long-Armed Gibbons (Tongbei yuanhou)
  4. Macaques (Mihou)

Recall how the names Tongbi and Tongbei both refer to the gibbon’s long arms. Therefore, the listed groups above are practically the same.

This then raises the question, “Were the Four Celestial Primates all born on Flower-Fruit Mountain, or are the similarities just an example of mirroring?” What I mean by this is that JTTW hosts a number of mirrored characters. Here are just a few:

  1. Sun Wukong and Six-Ears (ch. 56 to 58) – This one is obvious.
  2. Sun Wukong and the Bull Demon King (ch. 4 to 7 and 61) – They have the same powers and character arc (see section 3 here).
  3. The Demon Kings of the 72 Caves and the 72 Heavenly Commanders (ch. 4 to 5)
  4. Monkey’s Six Sworn Demon King Brothers (ch. 4) and Lord Erlang’s Six Sworn Brothers of Plum Mountain (ch. 6)
  5. Nezha and Red Boy (chapters 4 to 6 and 40 to 42) – Both are powerful, divine children associated with fire.

I’ll leave it up to the reader which possibility they want to accept.


Update: 02-20-22

Here’s a four minute preview for the upcoming film King of Havoc: Rise of the Great Sage (Hunshi zhi wang: Dasheng jueqi,  混世之王:大圣崛起, 2022). The Six-Eared Macaque appears in figure four wielding swords. This same character takes part in the trailer but is called the Macaque King, thereby referencing the aforementioned theory that he is Six Ears.


Update: 02-22-22

User Phantom86d left an interesting comment suggesting that the four celestial primates are not part of the ten categories of life—as stated by the Buddha in the introduction—”[b]ecause Wukong erased their names from the book of Life and Death.” This refers to chapter three when Sun inks out his name and those of all other primates when his immortal soul is mistakenly summoned to hell. It’s important to remember that he had his own, separate book (Wu & Yu, 2012, vol. 1, p. 140), so the other celestial primates likely had theirs.


Update: 02-25-22

Thanks to this dictionary, I learned that one late-Qing source, New Dialect (Xinfangyan, 新方言, early-20th-c.), associates “horse-monkey” (mahou, 馬猴) with various iterations of Chinese terms for macaque monkeys:

“Bathing-monkey” (muhou): “mother-monkey” (muhou); mother-monkey (muhou): “full-monkey” (mihou) – these are called “horse-monkey” (mahou), the sound of each one changing [in turn].

沐猴:母猴;母猴:彌[獼]猴,令人謂之馬猴,皆一音之轉。(the original doesn’t have punctuation)

This article explains that the second term refers not to a female primate but a macaque. The Annotation of the Shuowen jiezi (Shuowen jiezi zhu, 說文解字注, 1815) reads:

“Mother-monkey” (muhou) is the name of the beast, not the female. “Bathing-monkey” (muhou) and “hunting-monkey” (mihou) are changes in dialect. The characters are wrong.

母猴乃此獸名,非謂牝者。沐猴、獮[獼]猴皆語之轉,字之訛也。

Update: 02-26-22

The Compendium of Materia Medica (Bencao gangmu, 本草綱目, 1596) traces the etymology of “bathing monkey” (muhou, 沐猴):

The monkey likes to wipe its face as if bathing (mu), so it is called a “bathing (monkey).” Later generations mistook this mu for “mother,” and then mother for “full” (mi). The meaning is lost as errors compound.

猴好拭面如沐,故謂之沐,而後人訥沐為母,又謳母為獼,愈訥愈失矣。

It then directly connects muhou (母猴) to stable monkeys:

The Shuowen says: The characters (for macaque) look like “mother monkey” (muhou), but it’s a “bathing monkey” (muhou, i.e. macaque), not a female. Since a macaque resembles a hu-barbarian, he is also called hu-sun “grandson of a barbarian.” The Zhuangzi calls him ju. People who raise horses keep a macaque in the stables, which will ward off horse-diseases. The Hu barbarians call a macaque maliu, in Sanskrit books he is called Mosizha (makaṭa).

《說文》雲︰為字象母猴之形。即沐猴也,非牝也。猴形似胡人,故曰胡孫。 《莊子》謂之狙。養馬者厩中畜之,能闢馬病,胡俗稱馬留雲。 《梵書》謂之摩斯[吒]。

The section later explains how macaques (muhou, 母猴) help the horses:

The Classic of Horses states: Domesticated macaques (muhou) used in horse stables help avoid horse diseases [lit: bimawen]. Their monthly menstruation runs onto the grass, and once the horses eat it, they will never be sick.

《馬經》言︰馬厩畜母猴,闢馬瘟疫。逐月有天癸流草上,馬食之,永無疾病矣。

It just occurred to me that since Six Ears is an aspect of Sun Wukong’s mind, the other two celestial primates could be as well. All three being aspects of Sun’s mind would thus explain why they “are not classified in the ten categories [of life], nor are they contained in the names between Heaven and Earth” (Wu & Yu, 2012, vol. 3, p. 115). They aren’t classified because they were never born. They are simply personifications of Sun’s base and noble qualities. How and when they would have splintered from his psyche is the big question. 

I doubt I’m the first person to think of this. I’m interested to hear what my readers think.

I’ve rewritten sections two to four. This was done to help make the subject more understandable. 

Notes:

1) I will be altering Yu’s (Wu & Yu, 2012) translation from this point forward to make it more accurate.

2) Ctext shows the term “Great Horse-Monkey” (Da mahou, 大馬猴) pops up in chapter 28 of Dream of the Red Chamber (18th-century). It’s used to symbolize something worse than an immoral husband that would ravage a young maiden:

Next came Xue Pan. “Is it for me to speak now?” Xue Pan asked.

“A maiden is sad…”

But a long time elapsed after these words were uttered and yet nothing further was heard.

“Sad for what?” Feng Ziying laughingly asked.

“Go on and tell us at once!”

Xue Pan was much perplexed. His eyes rolled about like a bell.

“A girl is sad…” he hastily repeated. But here again he coughed twice before he proceeded.

“A girl is sad,” he said:

“When she marries a spouse who is a libertine.”

This sentence so tickled the fancy of the company that they burst out into a loud fit of laughter.

“What amuses you so?” shouted Xue Pan, “is it likely that what I say is not correct? If a girl marries a man, who chooses to forget all virtue, how can she not feel sore at heart?”

But so heartily did they all laugh that their bodies were bent in two.

“What you say is quite right,” they eagerly replied. “So proceed at once with the rest.”

Xue Pan thereupon stared with vacant gaze.

“A girl is grieved…” he added.

But after these few words he once more could find nothing to say.

“What is she grieved about?” they asked.

“When a huge horse monkey [大馬猴] finds its way into the inner room,” Xue Pan retorted (Cao & Joly, 1892, p. 62).

下該薛蟠。薛蟠道:「我可要說了:女兒悲--」說了半日,不見說底下的。馮紫英笑道:「悲什麼?快說!」薛蟠登時急的眼睛鈴鐺一般,便說道:「女兒悲--」又咳嗽了兩聲,方說道:「女兒悲,嫁了個男人是烏龜。」眾人聽了,都大笑起來。薛蟠道:「笑什麼?難道我說的不是?一個女兒嫁了漢子,要做忘八,怎麼不傷心呢?」眾人笑的彎著腰,說道:「你說的是,快說底下的罷。」薛蟠瞪了瞪眼,又說道:「女兒愁--」說了這句,又不言語了。眾人道:「怎麼愁?」薛蟠道:「繡房鑽出個大馬猴。」
