Fern: Adapting the Green Knight in Adventure Time

Sir Gawain and the Green Knight, the Middle English alliterative Arthurian poem, has long captured the imagination of audiences, medieval and modern. Recently, Valiant Comics has adapted the Sir Gawain and the Green Knight into a comic titled “Immortal Brothers: The Tale of the Green Knight” and brought the poem to modern audiences (2017). The same year, Emily Cheeseman adapted Sir Gawain and the Green Knight into a graphic novel (2017), which was funded by Kickstarter and which is now publicly available online.

Film adaptions of Sir Gawain and the Green Knight have also emerged in modern times, including Steven Weeks’ two movies based on the medieval story: Gawain and the Green Knight (1973), and then about a decade later, The Sword of the Valiant: The Legend of Sir Gawain and the Green Knight (1984), which famously features Sir Sean Connery as the Green Knight. While Weeks draws primarily from Sir Gawain and the Green Knight in his film adaptations of the medieval poem, he also borrows from other Arthurian legends, such as the tale of Sir Gareth in Thomas Malory’s Le Morte d’Arthur and Yvain, the Knight of the Lion by Chrétien de Troyes.

Moreover, last year a new film adaption of the poem, titled The Green Knight (2021), directed, written, edited, and produced by David Lowery, was released in theaters. This recent movie adaption of Sir Gawain and the Green Knight drew both praise and opprobrium from critics, prompting me to view and write my own review of the film. The Green Knight stars Dev Patel as Gawain, a nephew of King Arthur in this adaptation, who embarks on an epic quest to test his chivalry and confront the Green Knight.

But today, as I previewed in my previous post on adaptations of Beowulf in modern cartoons, I want to discuss the introduction of a character adaptation of the Green Knight in the final season of Cartoon Network’s Adventure Time. The episode that features and centers the Green Knight is called “Seventeen” (Season 10 Episode 5), in which the plot borrows substantially from the medieval alliterative poem, despite significant redactions and reworking on certain characters and themes from the source text.

As in the Middle English romance, the episode begins with feasting and a celebration. In Sir Gawain and the Green Knight, King Arthur and his court at Camelot are celebrating Christmas and Yuletide. In Adventure Time, the celebration centered on the 17th birthday of Finn the Human, who is also the main hero and one of the primary protagonists of the show, at Princess Bubblegum’s court in the Candy Kingdom. In both the medieval poem and modern cartoon series, the Green Knight rudely barges into court, unannounced, uninvited and riding on his green horse, before offering a green battle axe and proposing a dangerous challenge.

In “Seventeen” when the stranger enters, Finn exclaims “you’re green,” to which the guest responds “I’m the Green Knight.” Like in the medieval poem, Adventure Time‘s Green Knight is exceedingly green, from his armor and clothes, to his hands and face, and even his mount and weapon are all shades of green. The special attention the cartoon gives the green axe and green horse pays homage to the Middle English romance, which contains detailed descriptions of the green man, his green axe and his green steed.

In both the television series and Middle English poem, the Green Knight’s arrival is shrouded in anticipation and ladened with suspense. Just as in the original poem, the Green Knight in Adventure Time is a mystery knight, come to challenge the champion and test his opponent’s heroism and mettle. In keeping with its source, Adventure Time makes games central to the episode, beginning with the very game featured in the original poem.

The Green Knight gives Finn a birthday axe in S10E5 of Adventure Time, “Seventeen” (2017).

In Adventure Time, since it is Finn the human’s 17th birthday party, when the Green Knight arrives at the court of Princess Bubblegum, he gifts his green axe to Finn for the occasion. The Green Knight greets Finn by saying: “And before you ask, of course I brought you a birthday present. It’s a battle axe.” The Green Knight follows up with a cryptic caveat “But only if you play me a game for it.” As Gawain does in the Middle English romance, Finn accepts the battle axe and the Green Knight’s challenge, deciding to game with the mysterious guest.

Finn beheads the Green Knight in S10E5 of Adventure Time, “Seventeen” (2017).

As in Sir Gawain and the Green Night, the first birthday contest in “Seventeen” is a weird beheading game. When Finn asks which game they will play, the Green Knight describes the game: “Oh this game is called all you have to do is strike me with it and it is yours.” Finn struggles with the idea of “axing a stranger” but soon has a revelation. Noting the absence of his partner, Finn assumes that the mysterious Green Knight is nothing more than a birthday prank orchestrated by his best friend Jake, so the hero plays along and is unfazed by the uncanny strangeness of the proposed game. Finn deals what appears to be a death-dealing blow to the neck, decapitating the Green Knight, much like Gawain does in the original poem.

Again, as in its source, the Green Knight in “Seventeen” proves to be some sort of undead being, able to simply pick up and replace his head after his beheading. It is at this point that Jake arrives, signaling that the Green Knight is not an elaborate birthday hoax by Jake, and what was planned as a fun birthday turns into a fight for his life. Citing fairness, the Green Knight isolates Finn from the rest of his friends so that they cannot aid him, or warn him of any foul play on the part of the Green Knight.

Unlike in the Middle English romance, in “Seventeen” Finn asks for alternative games rather than allowing the Green Knight to return an axe stroke to his neck. This marks the major point of divergence in what follows as a loose adaptation. The stakes are set: if Finn wins, the Green Knight will reveal the mystery of his identity and the Green Knight makes plain his reward, stating, “if I win, chop, chop.”

The green horse interferes with the first game in S10E5 of Adventure Time, “Seventeen” (2017).

The Green Knight is able to win the first contest through deception and subterfuge, ideas central to the source text as well, and then the Green Knight allows Finn to win the second contest without competing at all, undercutting his heroism. This ultimately proves the only game in which Finn defeats his opponent. Again, the Green Knight has a trick up his sleeve, this time the plan is to allow Finn to expend his energy and strength, giving the Green Knight the upper hand in the decisive game between Bubblegum’s champion and the mysterious guest.

Green Knight is revealed as Fern in S10E5 of Adventure Time, “Seventeen” (2017).

Finn recognizes the trick immediately, but Finn believes his “robot arm” will continue to provide him with an advantage in the final contest of strength: an arm wrestling match. While Finn is able to compete with the Green Knight until the first mystery is revealed, once the hero learns that the Green Knight is none other than Fern, his formerly deceased, plant-form doppelgänger, he becomes overwhelmed causing him to lose their last game. The surprise of the Green Knight’s identity disarms the hero and allows Fern to easily defeat Finn. Fern, in Green Knight form, smashes his enemy upon the table, breaking it, and leaving Finn on the floor, vulnerable and in shock, as the Green Knight approaches, axe raised and ready to deliver a fatal blow.

These additional games replace the hunting and bedroom games featured in the Middle English romance, but the narrative of “Seventeen” nevertheless realigns with the original plot as the hero ultimately fails and appears as if he is about to be beheaded by his opponent. In the medieval poem, the Green Knight is revealed to be Bertilak, the lord who houses Gawain and whose wife seduces him. But the double reveal includes the revelation the it was Morgana Le Fay (2446), a witch and King Arthur’s half sister, who sent the Green Knight to Camelot to test the Knights of the Round Table and frighten Queen Guenevere.

Uncle Gumbald, Aunt Lolly & Cousin Chicle are revealed in S10E5 of Adventure Time, “Seventeen” (2017).

Similarly, in Adventure Time, the Green Knight is a servant of disgruntled, royal relatives. In “Seventeen,” the Green Knight is called off by his own steed, which is shown to be a mechanical horse in which three treacherous relations of Princess Bubblegum are hidden: Uncle Gumbald, Aunt Lolly and Cousin Chicle. The double mystery aspect of the cartoon mirrors the medieval poem’s dual reveal at the end of narrative, in both cases returning focus to intrafamily power struggles over the throne while simultaneously demonstrating the limitations of chivalry and the dangers of hubris. By the end, in both Sir Gawain and the Green Knight and “Seventeen” the royal champions are bested by the Green Knight, although in Adventure Time, the Vampire Queen Marceline is there to step in and scare off the intruders, causing the Green Knight to retreat into the night.

Marceline vs the Green Knight in S10E5 of Adventure Time, “Seventeen” (2017).

The way in which Adventure Time creatively adapts and reinvents Sir Gawain and the Green Knight for a broad modern audience carries forward the medievalism from “The Wild Hunt” (Season 10 Episode 1). Although at times the episode deviates dramatically from its source, Adventure Time makes the complex (at times enigmatic) medieval story both accessible and comedic, while retaining some of the key aspects including the fraught presentation of chivalry and heroism, thereby helping to set the stage for future generations of medievalists.

The Late Medieval Clerical Proletariat & the Vocational Crisis in Modern Academia

Educational training was the cornerstone of ecclesiastical and monastic life in the early medieval period, with the aim of producing knowledgeable clergy, who might then serve as spiritual and intellectual shepherds for their population. However, as Kathryn Kerby-Fulton explains in her recent monograph, The Clerical Proletariat and the Resurgence of Medieval English Poetry, because universities in the late Middle Ages were turning out more clergy than the church could hire in beneficed positions, many found themselves experiencing a crisis of vocation. Kerby-Fulton argues that this crisis produces a “clerical proletariat” many of whom ultimately become civil servants, secretaries in great households, writing office clerks, or casual liturgical laborers, especially in London. She shows how this crisis of mass underemployment is further exacerbated by pluralism (the unethical practice of hogging multiple benefices).

Beneficed priests were in a privileged position: they received both income from parish holdings and wealth from the church. Although medieval universities were producing highly educated clergy, there were more qualified candidates than ever before, while at the same time, beneficed priests were sometimes acquiring multiple benefices and then outsourcing the work of delivering the mass and managing the church operations to poorer paid vicars, chaplains and lesser church officials, while pocketing most of the money themselves.

Kerby-Fulton argues that this sharp increase in qualified clergy and decrease in beneficed positions, resulted not only in a vocational crisis and the creations of a clerical proletariat, but ultimately in a resurgence in Middle English poetry, as this class of clerks saw more opportunities for writing English because they were working for the laity, though many still worked with Latin (or French) documents all day long. Figures like Thomas Hoccleve, a late medieval poet-clerk, comment regularly on the financial struggles and tenuous existences of the unbeneficed clerical proletariat, observable in his poem “The Complaint” which states:

Thomas Hoccleve’s Signature; Durham University Library MS Cosin V.III.9, f.95r.

I oones fro Westminstir cam,
Vexid ful grevously with thoughtful hete,
Thus thoughte I: ‘A greet fool I am
This pavyment a-daies thus to bete
And in and oute laboure faste and swete,
Wondringe and hevinesse to purchace,
Sithen I stonde out of al favour and grace.

“When once I came from Westminster, very bitterly troubled with burning anxiety, I thought like this: ‘I am a great fool to beat these streets like this every day and to work doggedly and sweat indoors and outdoors, in order to earn nothing but restlessness and misery, since I am fallen out of all good fortune and grace.’” (Jenni Nuttall, 183-189).
In this passage, we learn how Hoccleve is very upset with his vocational prospects (184), and he deems himself a greet fool “great fool” (185) for working endless and performing in and oute laboure faste and swete “firm and sweaty labor, indoors and outdoors” (187) with nothing to show for it but wondringe and hevinesse “wandering and hardship” (188).

Thomas Hoccleve presents ‘The Regiment of Princes’ to King Henry V; British Library, MS Royal 17, D.vi f.40r.

Similarly, in his poem, The Regiment of Princes, Hoccleve laments how he initially pursued the priesthood but ultimately forgoes these dreams and instead marries. Hoccleve describes his vocational rollercoaster, emphasizing that at first he sought Aftir sum benefice “after some benefice” but states that whan noon cam, / By procees I me weddid atte laste, “when none came, in time, I did wed at last” (1452-53). Moreover, Hoccleve stresses that his initial reluctance to marry is specifically because he long held hopes of a career as a beneficed priest, explaining that I whilom thoghte / Han been a preest “for a while I thought I would have been a priest” (1447-48). In both poems, Hoccleve expresses his frustration with the vocational crisis of underemployment which produces the clerical proletariat that Kerby-Fulton examines in her book.

Members of the clerical proletariat loom large in Middle English literary culture, and various characters in Geoffrey Chaucer’s Canterbury Tales, including the Clerk of Oxenford, the hapless lover and parish clerk, Absolon (in the “Miller’s Tale“), and the noble Parson, who is perhaps the most virtuous figure on the pilgrimage. Similarly, William Langland (the author of Piers Plowman) was such a clerk, and likely so were the authors of the Owl and Nightingale and Laȝamon’s Brut. The University of Pennsylvania Press notes that “Taking in proletarian themes, including class, meritocracy, the abuse of children (“Choristers’ Lament”), the gig economy, precarity, and the breaking of intellectual elites (Book of Margery Kempe), The Clerical Proletariat and the Resurgence of Medieval English Poetry speaks to both past and present employment urgencies.”

Indeed, many modern untenured scholars (including myself), who work three or more academic jobs to pay the bills, will surely identify with the position Hoccleve voices in his complaint. As Kerby-Fulton insightfully observes in her book, the circumstances outlined in this late Middle English poem closely resemble the current crisis of vocation within modern academia, where well-paying tenured faculty positions are disappearing as the universities seek to outsource more and more of the work of education to adjunct professors, the modern equivalent of the late medieval clerical proletariat. Meanwhile, universities continue to produce an endless stream of highly skilled and qualified professionals, many of whom will sadly face chronic underemployment and even possible unemployment as a result of over-qualification and unethical practices now embedded in our private university system that is seemingly more concerned with profits than with the future of the academy.

Chaucer and the Internet: Revisiting the House of Fame

internet—“a network of networks” (Wikipedia)

“network: anything reticulated or decussated, at equal distances, with interstices between the intersections” (Dr. Johnson; johnsonsdictionaryonline.com)

Geoffrey Chaucer is remembered as an innovator who made the first translation of one of his contemporary Petrarch’s sonnets into English, and who may have initiated the now-universal association of St. Valentine’s Day with romantic love.  He may also, in his poetic dream vision The House of Fame, have given us a premonition of the staggering power and potential for misuse of the modern-day internet.  The narrator/protagonist of this poem, named Geoffrey, is taken to visit the goddess Fame by a giant eagle.  Her palace, which he visits first, is impressive but disappointing, as Geoffrey fails to find what he seeks there.  In the final 250 lines of the poem, he is taken to a nearby structure, which critics at least as far back as George Lyman Kittredge[i] have referred to as the House of Rumor. This is the section of the poem that forecasts the internet as we know it today.

Standard Symbol for the Internet and World Wide Web.

The eagle chides Geoffrey on their first meeting for his introverted habit of coming home every night to spend the evening like a hermit (or scholar during pandemic lockdown) with his books. What Geoffrey needs, and what the eagle has been sent by Jupiter to help him acquire, are “tidings” of what is happening in the world outside. The Middle English word “tidinges” is glossed as “news” in the Norton Chaucer.[ii]  The University of Michigan’s online Middle English Dictionary [iii] suggests a variety of other meanings, including “report,” “information” (both specific and general), “message,” “announcement,” “gossip,” and “rumor.”  All of these taken together seem to sum up the variety of things that people today search for on the internet.

The eagle tells Geoffrey that the House of Fame is located at a point equidistant from earth, sky, and sea, so that any spoken word from any of these locations must travel there. In the grand palace of Fame herself, however, Geoffrey does not find any of the “tidings” he seeks. He is then guided to another nearby structure, the so-called House of Rumor. Geoffrey labels it a “house,” and compares it to the labyrinth built by Daedalus in Greco-Roman mythology, but the term “House of Rumor” is never used in the poem. Critics have identified Chaucer’s source for this image with the house of fame described by Ovid in the 12th book of his Metamorphoses; although Ovid does say that thousands of rumors can be found there (“milia rumorum,” line 12:55), the goddess he places in charge is Fama (Fame), not Rumor.[iv]

 The structure itself is sixty miles long, made of twigs.  The twigs are woven together in a way that suggests baskets or cages to the narrator, and he notices thousands of holes throughout the weave. This presumably circular structure, formed of interlocking strands, is eerily like the visual depictions of the internet that are produced when it is imagined as a visible structure. The very name “internet” suggests such an interlocking construction to the mind. Today, we picture the strands in diagrams of the internet as the pathways along which our information travels, but for Chaucer, it is the holes in between the twigs that allow tidings to escape.

The entire structure of this house is constantly spinning, so fast that Geoffrey is unable to enter without the eagle’s assistance, and a loud noise issues from it. The noise the house makes as it spins is described first as resembling the sound of a stone flying from a catapult or that of a strong wind, but from inside come other sounds that Chaucer calls “gigges” and “chirkinges” (lines 1942-43), which Eleanor Parker in “Chaucer’s Post-Truth World” links to “tweets” and “Twitter”—after all, the entire house has already been compared to a bird cage.[v]  The twittering sounds are presumably made by the tidings themselves, which Chaucer does seem to imagine like birds in a cage.  In all, we are presented with a bewildering sense of speed and power associated with the house, coupled with the impression that the tidings, while they may be small, have a life and energy all their own.

The only way for Geoffrey to enter the structure is with the help of the eagle, who acts like a modern search engine. When he drops Geoffrey through a window, the structure stops spinning for a moment and allows his entrance. Inside, Geoffrey finds “tidings” of every sort—news about war and peace, work and leisure, life and death, loss and gain, and even about such things as weather and the prices of goods. All the tidings are being shared from person to person among a great crowd of figures that fills the space; Geoffrey had been told earlier by the eagle that these are embodied figures representing the people who first spoke the tidings down on earth. Like a game of “telephone,” the tidings are passed from ear to ear, growing with each repetition, until when each tiding reaches its full size, it flies through a window to spread itself freely—essentially “going viral.” 

Some of the tidings Geoffrey observes are true, and some are false. Both are being spread with equal enthusiasm. We are not told how Geoffrey is able to tell the difference, but within the dream vision, it is apparently obvious. He also notices that, as they try to escape through the spaces between the twigs, sometimes two tidings will become stuck as they squeeze through the same hole, so that he sees many instances in which a true tiding and a false tiding become stuck together and intermingled so that no one henceforth will be able to separate them again. All of this seems to be a very prescient depiction of the way that information both true and false is spread on today’s internet with incredible speed, growing and changing as it is repeated so that it is very difficult to tell whether much of it is true, false, or a blend of both.

Living and working in London as he does, Geoffrey would already be positioned to hear most of the tidings spreading through his world.  The intervention of Jupiter and his giant eagle seems unnecessary just to bring Geoffrey news, and in fact he never gains any concrete tidings within the confines of the poem. The true gift that he is being given may be this, even temporary, ability to discern the difference between true and false tidings, which those who encounter the tidings after they escape the House of Rumor clearly cannot do. Nor, unfortunately, can many users of the internet in our own day.

Chaucer’s poem, which he left unfinished, does not manage to provide a satisfactory solution to the problem.  As Geoffrey is walking around listening for tidings, his attention is drawn by a loud noise in the corner where love tidings are shared. Everyone in the structure rushes to this corner, pushing and straining to hear some important announcement. In the last lines of the poem as we have it, a figure appears that Geoffrey says he cannot identify, except that “he seemed for to be/ A man of gret auctoritee” (“great authority,” lines 2157-58). As soon as a “great authority” appears, someone whose word seems to represent true and reliable information, the entire structure of the House of Rumor apparently collapses—or at least, Chaucer has no more to say about it. For hundreds of years, readers have debated Chaucer’s intended identity of this “great authority.” Users of today’s internet likewise seem unable to identify yet still seek an authoritative source of information that would have the power to quell rumor and uncertainty. If our culture could find such a universally recognized source as an alternative to our current twittering, buzzing, rumor-laden communications, many of our cultural conflicts might even vanish, like a dream in a dream vision poem.
