Type “Sun Wukong” into google images and you will be presented with an endless array of pictures that range from the familiar to the alien. A fanciful 1960s cartoon depiction of our hero sits to the left of a SMITE video game character with hulking muscles and a weapon more akin to a club than a staff. A toy version of Liu Xiao Ling Tong‘s much beloved 1986 TV portrayal sits above an anime character with blond hair and a shaved chest. It seems there are as many depictions of Wukong as he has transformations. But how do these myriad personas compare to his depiction in the novel, and who has produced the most authentic look? In this article I present the Monkey King’s literary description, along with ancient depictions that predate the novel. My hope is that the information will be both interesting and useful, especially for artists and cosplayers looking to make a more authentic design.
1. Ancient Depictions
Some readers may be surprised to learn that stories about a “Monkey Pilgrim” (Hou xingzhe, 猴行者) go all the way back to the Song Dynasty (960-1279). This predates the actual name Sun Wukong by centuries. The literary episodes we all know and love began life as oral tales that evolved over time and grew into an accepted storytelling cycle which started to solidify by the 15th-century.  But the further we go back in time the less familiar the recorded material becomes (I will return to this shortly), and due to the memory-based nature of oral storytelling,  records for the earliest repertoires do not exist. Luckily, visual media from the Song survives, allowing us to see how artists of that time depicted the Monkey King.
Eastern Thousand Buddha Cave (Dong qianfo dong, 東千佛洞) number two in the Hexi Corridor of Gansu Province contains an 11th-century (Xixia dynasty) wall painting of Xuanzang worshiping Guanyin from a riverbank, while Monkey stands behind him tending to a brown horse. The latter is portrayed with a plain circlet on his head, a homely face with an overbite, waist length hair (or possibly even wearing a fur on his back), and light blue-green robes with a red apron and brown pants and sandals (fig. 1 and 2). The depiction is less simian in appearance, yet not wholly human.

Yulin Cave (Yulin ku, 榆林窟) number three in Gansu contains an 11th to 12th-century wall painting with similar imagery. Xuanzang is again worshiping from a riverbank, but this time the subject of adoration is Samantabhadra. We see Monkey lacks the fillet but wears a monk’s robe with wrapped socks and sandals. This time he is far more monkey-like in appearance, complete with furry arms (fig. 3 and 4).
Fig. 3 – An almost complete version of the 11th to 12th-century Yulin Cave no. 3 painting (larger version). Monkey and Xuanzang can be seen standing on the river bank on the upper left side. Fig. 4 – A detail of the two figures (larger version).
Despite the lack of written evidence from this time, the fact that the Monkey Pilgrim appears in picture form in two noted Buddhist cave grottoes shows the story was well known as early as the 11th-century. It’s not impossible to imagine that the oral tales go back further to the previous century or even before the Song itself.
A circa 1237 stone relief carving of what many scholars believe to be an early version of Monkey resides on the western pagoda of the Kaiyuan Temple (開元寺) in Quanzhou, Fujian province. This muscular warrior wears the headband, earrings, bracelets, a rosary necklace, and possibly even arm bangles (all prescribed Esoteric Buddhist ritual accouterments), as well as a monk’s robe and sandals. He wields a broadsword in one hand, while the other thumbs the rosary at his chest. At his waist hangs a calabash gourd and a scroll of the Mahamayurividyarajni Sutra (Fomu da kongque mingwang jing 佛母大孔雀明王經) (fig. 5) (Ecke & Demiéville, 1935). He has the large ears and protruding mouth of a monkey.

Writing in the 1250s, the Song poet Liu Kezhuang (劉克莊, 1187-1269) references our hero twice in his work. The second of two such references uses Monkey as a metaphor to describe the ageing 70-year-old’s appearance. A portion of the poem reads:
A back bent like a water-buffalo in the Zi stream [泗河],
Hair as white as the silk thread issued by the “ice silkworms”,
A face even uglier than Hou Xingzhe [the Monkey Pilgrim],
Verse more scanty than even He Heshi [鶴何師] (Dudbridge, 1970, p. 46)
Ugliness is a subject I will return to several more times.
I mentioned earlier that the farther we go back in time the less familiar the recorded material becomes. Case in point is the The Story of How Tripitaka of the Great Tang Procures the Scriptures (c. late 13th-century), the earliest published edition of Journey to the West. Despite referring to himself as “the bronze-headed, iron-browed king of the eighty-four thousand monkeys of the Purple Cloud Grotto on the Mountain of Flowers and Fruit” (Wivell, 1994, p. 1182), the Monkey Pilgrim is depicted as a white-clad scholar. Another difference is the fact that he fights with two different staves, one a ringed monk’s staff and the other an iron rod (these two would later be combined to create his signature weapon).
The majority of Song sources depict the Monkey Pilgrim as the size of an adult man but with the head of an ugly monkey. Reasons for why he is depicted this size could be because the respective artists lived in areas devoid of such animal examples, or that they simply imagined a monk like themselves (for the artists were likely ordained) with monkey features. Another reason could be that they were influenced by early stage portrayals, which would obviously entail an adult actor taking on the role.
2. What the novel says
2.1. Physical appearance
The earliest descriptions of what Monkey looks like appear in chapter one. When he is first taken in by his teacher Subodhi, the immortal tells him, “Though your features are not the most attractive, you do resemble a pignolia-eating macaque [husun, 猢猻].”  After he returns to the Mountain of Flowers and Fruit, a demon king refers to Monkey’s height: “You’re not four feet tall” (Wu & Yu, 2012, vol. 1, p. 128).
In chapter 7, Monkey is subjected to Laozi’s eight trigrams furnace as punishment for his crimes against heaven. He survives the celestial fire but the smoke inside “…reddened his eyes, giving them a permanently inflamed condition. Hence they were sometimes called Fiery Eyes and Diamond Pupils [Huoyan jinjing, 火眼金睛] (Wu & Yu, 2012, vol. 1, p. 189). The anthropologist Frances D. Burton (2005) explains his fiery eyes are “a characteristic he shares with the actual red-rimmed eyes of M. mulatta [the Rhesus macaque]” (fig. 6) (p. 148).
Fig. 6 – A comparison of Rhesus macaque males with red-rimmed eyes during mating season (left) and other times (right) (larger version). Original image from Dubue, Allen, Maestripieri, & Higham, 2014, p. 5.
In chapter 20, the reader learns that Monkey’s head is bald (fig. 7). An old man asks him: “…why did you shave your hair to become a monk?” (Wu & Yu, 2012, vol. 1, p. 395).
In chapter 21, a demon king steps out of his cave to fight Sun but is surprised by his small stature:
The old monster took a careful look and saw the diminutive figure of Pilgrim [Monkey]—less than four feet, in fact—and his sallow cheeks. He said with a laugh: “Too bad! Too bad! I thought you were some kind of invincible hero. But you are only a sickly ghost, with nothing more than your skeleton left!” (Wu & Yu, 2012, vol. 1, p. 408). (Thank you to Jose Loayza for bringing this passage to my attention.)
His bald head is referred to again in chapter 27: “But ever since Nirvana delivered me from my sins, when with my hair shorn I took the vow of complete poverty and followed you as your disciple, I had this gold fillet clamped on my head” (Wu & Yu, 2012, vol. 2, p. 24). (Thank you to Stanley Setiawan for bringing this passage to my attention.)
Fig. 7 – Reggie the baboon from Paignton Zoo (circa 2005). His slick head was the result of his mom’s “over-zealous” grooming. Look at those ears! He’s the wrong genus and species, but you get the general idea what Sun Wukong would look like wearing the golden fillet (larger version).
Wukong’s bald pate is once again referenced in chapter 34: “The fiend then gave the rope a tug and pulled Pilgrim down before he gave that bald head seven or eight blows with the sword. The skin on Pilgrim’s head did not even redden at all” (Wu & Yu, 2012, vol. 2, p. 128).
In chapter 44, the Monkey King’s appearance is revealed in a dream to a group of monks by the personification of the planet Venus:
A bumpy brow, and golden eyes flashing;
A round head and a hairy face jowl-less;
Gaping teeth, pointed mouth, a character most sly;
He looks more strange than [the] thunder god (Wu & Yu, 2012, vol. 2, p. 276).
In chapter 49, a monster who barely survived a battle with Sun Wukong describes his appearance to a friend: [H]e has a hairy face and a thunder god beak … forked ears and broken nose. A monk with fiery eyes and diamond pupils (Wu & Yu, 2012, vol. 2, p. 353).
In chapter 58, Sun Wukong’s doppelganger is described as having matching features:
A hairy face, a thunder god beak,
An empty jowl unlike Saturn’s;
Two forked ears on a big, broad head,
And fangs that have outward grown (Wu & Yu, 2012, vol. 3, p. 105).
In chapter 75, he once again tests the hardness of his bald head:
“‘If your bald head can withstand three blows of my scimitar, I’ll let you and your Tang monk go past’ … Arousing his spirit, the old demon stood firmly with one foot placed in front of the other. He lifted up his scimitar with both hands and brought it down hard on the head of the Great Sage. Our Great Sage, however, jerked his head upward to meet the blow. All they heard was a loud crack, but the skin on the head did not even redden” (Wu & Yu, 2012, vol. 3, p. 373).
In chapter 77, an old man chastises Monkey for offending him:
You! Look at your skeleton face, flattened brow, collapsed nose, jutting jowl, and hairy eyes. A consumptive ghost, no doubt, and yet without any manners at all, you dare use your pointed mouth to offend an elderly person like me!” (Wu & Yu, 2012, vol. 3, p. 242).
We can see from these quotes several features that appear again and again. These include a furry, joweless face with fiery eyes, a broken or flat nose, a beak-like mouth with protruding fangs, and forked ears. The author-compiler of the novel uses these features over and over again to remind the reader just how ugly the Great Sage is. These same features are also shared by the Rhesus monkey and other macaque species (fig. 8). The multiple mentions of the Thunder God‘s beak refers to the monkey’s prognathic (protruding) mouth, which houses large canine teeth. The quotes also let us know that Sun Wukong is less than four feet tall and very skinny (e.g. having “sallow cheeks” and being like “a consumptive ghost”) just like a monkey (fig. 9). It’s important to note that Sun is described as being bald numerous times throughout the novel. This should come as no surprise since he was required to take the tonsure as a Buddhist monk. Modern depictions often deviate from the features mentioned here (more on this below).

2.2 Clothing and accessories
The novel mentions Sun Wukong wearing different attire throughout his roughly 1,100 years of life. Here I will focus on that which is closely associated with his traditional iconography.
The clothing most often associated with Monkey is his suit of armor. He receives it from the dragon kings of the world’s oceans in chapter 3:
“I have here a pair of cloud-treading shoes [bu yun lu, 步雲履] the color of lotus root[, said Aoshun, the Dragon King of the Northern Ocean]. Aorun, the Dragon King of the Western Ocean said, “I brought along a cuirass of chainmail made of yellow gold [Suozi huangjin jia, 鎖子黃金甲].” “And I have a cap with erect phoenix plumes, made of red gold [ding fengchi zijin guan, 頂鳳翅紫金冠],” said Aoqin, the Dragon King of the Southern Ocean (Wu & Yu, 2012, vol. 1, p. 137).
Those wanting to make a novel accurate suit should consult Ming-era chainmail (fig. 10). However, the oldest drawing of Wukong wearing armor that I’m aware of depicts him with “mountain pattern” armor (fig. 11). Combinations of mountain pattern armor and feather caps can be seen in the 16th-century scroll The Emperor’s Return to the Capital (Rubitu, 入蹕圖) (fig. 12), showing it was part of historical military regalia and not just the purview of Chinese opera (fig. 13). Modern depictions of Monkey tend to portray him wearing mountain pattern armor with ornate beast elements on the shoulders and waist. Those wishing to replicate this kind of armor should consult Ming-era statues of Buddhist protector deities, such as Skanda or the Four Heavenly Kings (this blog is especially good) (fig. 14, for example). Modern “Purple Gold Caps” (zijin guan, 紫金冠) with lingzi (翎子) feathers should be used for Sun’s phoenix feather cap (fig. 15).

Contrary to popular belief, Sun does not wear the armor throughout the entire story. Though not openly stated, the novel suggests it is stripped from the monkey when he is captured by heavenly soldiers in chapter six: “They bound him with ropes and punctured his breast bone with a knife, so that he could transform no further” (Wu & Yu, 2012, vol. 1, p. 186). Obviously the knife wouldn’t have punctured the magic armor. And after heaven fails to harm his body during an attempted execution, one celestial reports:
Your Majesty, we don’t know where this Great Sage has acquired such power to protect his body. Your subjects slashed him with a scimitar and hewed him with an ax; we also struck him with thunder and burned him with fire. Not a single one of his hairs was destroyed. What shall we do? (Wu & Yu, 2012, vol. 1, p. 186). (emphasis mine)
Prior to his turn in Laozi’s eight trigrams furnace in chapter seven, the story again references the knife in Monkey’s breastbone, suggesting he is still naked: “Arriving at the Tushita Palace, Laozi loosened the ropes on the Great Sage, pulled out the weapon from his breastbone, and pushed him into the [brazier]” (Wu & Yu, 2012, vol. 1, p. 189). One late-Ming woodblock print actually portrays him naked upon his escape from the furnace (fig. 16). Most importantly, after being released from his 600 plus-year-long imprisonment under Five Elements Mountain, Monkey is expressly described as being “stark naked” (chi tiao tiao, 赤條條) (Wu & Yu, 2012, vol. 1, p. 309).
The lack of clothing leads to his second most identifiable and longest-worn piece of attire, a tiger skin kilt (hu pi qun, 虎皮裙) (fig. 17). After killing the beast in chapter 14, Monkey:
[Slit] the skin straight down, he then ripped it off in one piece. He chopped away the paws and the head, cutting the skin into one square piece … He cut it again into two pieces; he put one of these away and wrapped the other around his waist. Ripping off a strand of rattan from the side of the road, he firmly tied on this covering for the lower part of his body (Wu & Yu, 2012, vol. 1, p. 310).
Fig. 17 – A modern depiction of Sun Wukong with a tiger skin kilt (larger version). By the author.
Monkey’s most recognizable accessory is the self-control-inducing golden fillet (jingu quan, 金箍圈), which he is tricked into wearing as a punishment shortly after murdering six bandits in chapter 14. As noted above, the band predates the novel, appearing in the 11th-century Eastern Thousand Buddha Cave number two painting. This piece depicts the headgear as a simple circlet devoid of any decoration (fig. 18). This matches the novel’s description of “a thin metal band” (jinxian, 金線) (Wu & Yu, 2012, vol. 1, p. 310). But as can be seen from the Kaiyuan temple pagoda relief, there also exists a version with a double curlicue pattern in the center of the forehead (fig. 19). This has come to be the most popular version used in modern media.
Fig. 18 – Detail of the Monkey Pilgrim’s fillet from Eastern Thousand Buddha Cave no. 2 (c. 11th-cent.) (larger version). Image enhanced slightly for clarity. Fig. 19 – Detail from the Kaiyuan Temple pagoda relief (1237) (larger version).
As for other attire, there exists one passage in chapter 58 that describes how Monkey’s doppelganger copied even his clothing:
His looks were exactly the same as those of the Great Sage: he, too, had a gold fillet clamped to his brownish hair, a pair of fiery eyes with diamond pupils, a silk shirt on his body, a tiger kilt tied around his waist, a golden-hooped iron rod in one of his hands, and a pair of deerskin boots [jipi xue, 麂皮靴] on his feet (Wu & Yu, 2012, vol. 3, p. 105).
This appears to be the most detailed description of Monkey’s everyday clothing. It is similar to later Japanese depictions.
There is a distinct order in which Sun Wukong wears the aforementioned clothing and accessories: the armor, then the tiger skin, and then the golden fillet. However, many modern depictions portray Monkey wearing both the armor and headband. This is obviously anachronistic within the novel’s fictional story line. (Admittedly, though, this is not unique to the modern era. See figure 11 for a 16th-century example.) Furthermore, many depictions dismiss the tiger skin kilt altogether.
2.3. The staff
Monkey’s staff is first introduced in chapter three when he travels to the undersea palace of the dragon king to procure a divine weapon. There, he is directed towards a massive iron pillar:
Wukong girded up his clothes and went forward to touch it: it was an iron rod more than twenty feet long and as thick as a barrel. Using all his might, he lifted it with both hands, saying, “It’s a little too long and too thick. It would be more serviceable if it were somewhat shorter and thinner.” Hardly had he finished speaking when the treasure shrunk a few feet in length and became a layer thinner. “Smaller still would be even better,” said Wukong, giving it another bounce in his hands. Again the treasure became smaller. Highly pleased, Wukong took it out of the ocean treasury to examine it. He found a golden hoop at each end, with solid black iron [hei tie, 黑鐵] in between. Immediately adjacent to one of the hoops was the inscription, “The Compliant Golden-Hooped Rod. Weight: 17,560 pounds [Ruyi jingu bang zhong yiwan sanqian wubai jin, 如意金箍棒重一萬三千五百斤]” (Wu & Yu, 2012, p. 135). 
A poem in chapter 75 describes how the staff is decorated with magic symbols:
The rod of steel [bintie, 鑌鐵] nine cyclic times refined
Was forged in the stove by Laozi himself. 
King Yu took it, named it “Treasure Divine,” [Shen zhen, 神珍]
To fix the Eight Rivers and Four Seas’ depth.
In it were spread out tracks of planets and stars,
Its two ends were clamped in pieces of gold.
Its dense patterns would frighten gods and ghosts;
On it dragon and phoenix scripts were drawn.
Its name was one Rod of Numinous Yang [Lingyang bang, 靈陽棒],
Stored deep in the sea, hardly seen by men
[…] (Wu & Yu, 2012, vol. 3, p. 375)
So we see the staff is depicted as a rod of black iron or steel adorned on both ends with a single golden ring and decorated along the body with astronomical charts and an inscription towards one tip listing the weapon’s name and weight. The literary description greatly differs from modern media which often portrays it as entirely gold or red in color.
Those wishing to replicate the inscription on the staff can use figure 20 as a template. The characters are presented in “Small Seal Script” (小篆), which hails from the Qin Dynasty (221-206 BCE) when written Chinese was standardized by Qin Shihuang. Using this will give the staff a more ancient look. I used the template years ago to create a replica staff for an archaeology course in college.

3. Popular depictions
The following two sections include a small sampling of what I consider to be the least and most accurate portrayals in past and modern media. These are presented in no particular order.
3.1. The least accurate
1) SMITE video game – He’s basically a bodybuilder with mutton chops (fig. 21). The design includes the aforementioned headband plus armor anachronism. Why is he wearing a gladiator-style pauldron? The original illustration is by Brolo on deviantart.
Fig. 21 – “Do you even lift?” Wukong (larger version).
2) Warriors Orochi video game – Mutton chops, frosted tips, and an outfit borrowed from Prince’s wardrobe (fig. 22). Words fail me.
Fig. 22 – “Backup Dancer” Wukong (larger version).
3) The Forbidden Kingdom (2008) – Jet Li has a blond ponytail, mutton chops, and a soul patch (fig. 23). Need I say more?
Fig. 23 – “L’Oréal Paris” Wukong (larger version).
3.2. The most accurate
1) Yoshitoshi (1839-1892) – This Japanese artist produced many woodblock prints of our hero. Take for example his Modern Journey to the West series completed between 1864 and 1865. He portrays Sun Wukong as a red-faced snow macaque, which aligns more with the literary description (fig. 20).
Fig. 24 – Wukong salutes Xuanzang (larger version).
2) Journey to the West: Conquering the Demons (2013) – This dark comedy depicts the Great Sage as a short, ugly primate wearing golden armor (fig. 25).
Fig. 25 – Wukong prior to becoming Xuanzang’s disciple (larger version).
3) Journey to the West (2011) – This television series is a faithful adaptation of the novel. Although the actor who plays Sun Wukong is normal height, he wears a full silicone mask and clawed gloves to give the character a more primate look. His golden chainmail armor and staff are more accurate too. The latter even includes decorations on the shaft (fig. 26).
Fig. 26 – Wukong during his rebellion against heaven (larger version).
The novel portrays Sun Wukong as an ugly, bald Rhesus monkey less than four feet tall. His traditional literary attire includes a phoenix feather cap, golden chainmail armor, and lotus root-colored boots. Later, he wears a golden fillet, a silk shirt, a tiger skin kilt, and leather boots. He wields a rod of black iron/steel adorned on both ends with a single golden ring and decorated along the body with astronomical charts and an inscription towards one tip listing the weapon’s name and weight.
I have written this article in the hopes that it will serve as a resource for artists and cosplayers looking to make more authentic designs. Someone may remark: “Why bother? Monkey is a fictional character, so he can take any shape the artist desires.” My reply would be that all such characters have a prescribed iconography, otherwise they are not recognizable. It would be like drawing Harry Potter without the glasses and the scar, and then continuing to change lots of other stuff. At some point it’s no longer Mr. Potter but a completely different character altogether.
My friend Alexandre Palheta Coelho (instagram and deviantart) has drawn a novel accurate depiction of Sun Wukong based on the above information (fig. 27). As can be seen, it differs greatly from that usually portrayed in modern media. Take note of the small stature, the bald head, and especially the primate features. Recent movies and TV shows have portrayed Monkey as a young, handsome human in order to make him a love interest. History is not on the side of such depictions. As mentioned above, stories of Sun Wukong’s ugliness have spanned the centuries.
As mentioned above, the novel describes Wukong being “less than four feet, in fact”. I have made a chart comparing his height with that of a 6 ft (1.82 m) human man (fig. 28). This should serve as a good illustration for just how short our hero is.
Fig. 28 – Size chart (larger version).
I’ve written an article suggesting a mantra for the secret spell that causes Sun Wukong’s golden headband to tighten. Similar to the above article, I had artists and fanfiction authors in mind when I wrote it.
1) The 15th-century zaju play Journey to the West contains many familiar episodes that would come to appear in the final novel.
2) See the introduction of Dudbridge (1970), for example.
3) Source altered slightly. The original quote states, “…you do resemble a pignolia-eating monkey (husun)” (Wu & Yu, 2012, p. 115).
4) Yu’s (Wu & Yu, 2012) original translation says “thirteen thousand five hundred pounds” (Wu & Yu, 2012, vol. 1, p. 135). However, the Chinese version uses jin (斤), known in English as “catty“. The catty and pound are two different measures of weight, the former being heavier than the latter. Therefore, the English text has been altered to show this. The catty during the Ming Dynasty when the novel was compiled equaled 590 grams (Elvin, 2004, p. 491 n. 133), so 13,500 catties would equal 17,560 lbs.
5) The substance bin tie (鑌鐵), also known as Bin iron, was a high quality steel imported to China from Persia. The Yuan Dynasty government set up an office named after the material and possibly catered to elite blacksmiths (Sen, 2017, pp. 104-105).
