In this blog post, we’ll examine how Chrétien’s ‘The Story of the Grail’ established the Holy Grail as a symbol within the legend of King Arthur, and what roles the creative works of French authors and the oral traditions of Britain played in this process.

The Origins of the Holy Grail Story

The tales of King Arthur are widely accessible, ranging from childhood reading material to movies and popular novels. The concept of the “Holy Grail” became widely known through the recent bestseller ‘The Da Vinci Code’, bringing this ancient narrative even closer to the general public. So when, where, and how did this story first take root?
Since the story is set in England, one might easily assume it is based on ancient English legends; however, the Arthurian legend’s full-scale development took place primarily through the works of French authors from the mid-12th century to the mid-13th century. Even “The Death of King Arthur” by the 15th-century English author Thomas Malory is, in fact, a work based on a popular version of the Arthurian tales compiled in 13th-century France.
During the Middle Ages, the story of King Arthur spread throughout Western Europe, as well as to Bohemia and Cyprus, and translations were even produced in Greek and Hebrew. Thanks to this success, the Arthurian legend became a distinctively medieval European mythology comparable to Greek and Roman mythology. The symbol that expands the breadth and depth of the stories is the Holy Grail, and the work in which the seeds of the Holy Grail first appear is Chrétien de Troyes’ ‘The Story of the Grail’ (c. 1185). The Grail can be considered the central driving force of the entire Arthurian cycle.

King Arthur and His Kingdom

Questions about whether Arthur was a real historical figure have always been raised. Like many myths and legends, the Arthurian legend may have originated from stories surrounding a historical figure. Some British historical texts spanning the 6th to 9th centuries mention a British general who fought against the Anglo-Saxon settlers, but it is difficult to conclusively identify this figure as the Arthur we know based solely on such fragmentary records.
Meanwhile, in northwestern Britain—including Wales and Cornwall—ancient Celtic myths and folktales have been preserved through oral tradition, and Arthur and his companions appear within these traditions. The supernatural adventures stemming from these oral traditions constitute a significant portion of the Arthurian legend. Collections of Welsh tales, such as the ‘Mabinogion’ compiled by Charlotte Guest and others in the 19th century, are known as prime examples of these traditions.
The image of Arthur as we know it today was first systematized in the 12th-century Latin work ‘History of the Kings of Britain’ (c. 1136) by Geoffrey of Monmouth, a Welshman. Although this book takes the form of a historical account, it is largely filled with fictional imagination; it established Arthur’s life story by incorporating him into an epic framework beginning with Brutus, a descendant of Troy. Based on this work, Arthur is portrayed as a conqueror and the ruler of the civilized world, and his court is presented as the center of chivalry.
Although Geoffrey’s account is presented as a Latin translation of British sources in accordance with the conventions of the time, it actually contains a great deal of creative invention. The work gained widespread popularity, and the “Brut” (1155)—a French verse translation by Wace of Normandy—is considered a particularly significant adaptation. Wace and Geoffrey reinforced elements that would become central to later traditions, such as the establishment of the Round Table.
However, in the works of Geoffrey and Wace, Arthur’s reign is generally depicted as a succession of wars, and the tales of chivalric adventure we are familiar with today are rare. There is a mention of a “twelve-year peace” following the conquest of Ireland; however, this is merely a brief description stating that courtly etiquette was established and Arthur’s fame spread widely during this exceptional period of peace, with no specific tales of adventure recorded. Such tales were created and expanded in France while retaining the framework of Britain.

Stories of the Knights

Twelfth-century France was a period of cultural awakening, often referred to as the “Renaissance of the 12th Century.” Around this time, following the tradition of chivalric poetry, the genre of the “roman” emerged; its origins can be traced to the translation and adaptation of ancient novels such as the Trojan, Theban, and Alexandrian tales. The term “roman” was derived from the translation of these Latin originals into the local Romance languages.
Once the heyday of the ancient roman renaissance had passed, the genre declined due to limitations in subject matter and shifts in historical perception, and the tales of Britain emerged as a new trend in its place. Thus, French literature of the time began with the chivalric romances—narratives of Charlemagne and other heroes—progressed through the ancient romances adapted from Greek and Roman mythology, and finally entered the realm of full-fledged fictional literature with the introduction of the British cycle.
The term “British cycle” does not refer solely to the historical works of Geoffrey or Wace. They also encompass the vast body of traditions and oral tales passed down by troubadours, and stories not directly related to Arthur—such as those of Tristan and Isolde—also fell into this category. Due to the fantastical nature of these traditions, they allowed for greater imagination and freedom of adaptation than the other two genres.
There are various explanations as to why stories set on the island of Britain, in particular, became a source of inspiration for French writers. One explanation attributes this to the active creation and circulation of these stories at the court of Eleanor of Aquitaine—who became the queen consort of King Henry II of England—and her daughter, Marie de Champagne. Another view suggests that French poets were drawn to the fantastical nature of the material itself and the symbolic significance of courtly culture. Following Geoffrey, Arthur’s court was regarded as the epicenter of courtly culture, and French poets projected the chivalric society of their time onto that court and its wondrous world of adventure, weaving tales in which ideals and reality were intertwined.
Chrétien de Troyes is a representative author of the early generation who wrote the tales of Britain in novel form. Details of his life can only be inferred from a few clues in his works; he is believed to have been born around 1135–1140 in Troyes, in the Champagne region, to have been active at the court of Marie de Champagne between 1160 and 1172, and to have died around 1191. His major works include ‘Erec and Enide’, ‘Cliges’, ‘Lancelot, or The Knight of the Cart’, ‘Yvain, or The Knight of the Lion’, and the unfinished ‘Tale of the Grail’ (Conte du Graal). In these works, he does not dwell extensively on events such as King Arthur’s birth, coronation, various wars, death, and the fall of the kingdom—topics covered by Geoffrey or Wace—but instead uses King Arthur’s court as both a starting point and a destination, focusing the narrative on the wondrous adventures the knights experience in the fantastical world beyond the court.
These chivalric tales share a single fundamental theme. The common journey pursued in various novels of the time was for the protagonist to marry a bride upon reaching adulthood, succeed his father (or become king), and establish his own identity. In other words, they were a kind of “marriage novel.” Chrétien’s novel treated this journey through a dichotomous structure. The first half recounts the protagonist’s superficial achievements, while the second half deals with the process of resolving the problems arising from those achievements—namely, the conflicts of love. Through this, he moves away from the tragic love of Tristan and Iseult and presents “amour courtois”—the courtly love unique to medieval feudal society—as an ideal, seeking to resolve conflicts between opposing elements such as the ideals and realities of medieval society, reason and instinct, and social norms and individual rights.
However, his final and unfinished work, “The Story of the Grail,” takes on a different tone. While the first half—in which the protagonist, raised in a remote forest without knowing his true identity (name), goes to King Arthur’s court to become a knight, undergoes various adventures, and wins a beautiful bride—resembles his earlier works, the second half takes a completely different turn. Before his wedding, the protagonist sets out to find his mother, whom he had left behind in his hometown, and witnesses the procession of the Grail at a strange castle. A lance dripping with blood, brightly lit candlesticks, the Grail shining more brilliantly than the candlelight—boys and girls carrying silver trays file past his table. Though he wonders, “Why is blood dripping from the lance?” and “To whom is the Grail being taken?” but is unable to ask them, only to wake up the next morning in an empty castle. It was later revealed that had he posed those questions, he could have saved the inhabitants of the Fireland—namely, the Fisher King and his kingdom. However, the latter half of the story unfolds in a direction unrelated to the resolution of these mysteries and ultimately ends unfinished.
This bizarre ending caused a huge stir. What is the “Grail”? Why does blood flow from the spear that precedes the Grail? What does it mean that asking questions about the Grail saves the king and his kingdom? Who is the Fisher King? The prophecies regarding the sword given to the protagonist by the Fisher King and the downfall of the Kingdom of Logres (another name for King Arthur’s kingdom) also remained unresolved. How would the protagonist solve all these mysteries? The questions left by “The Story of the Grail” opened the door to various interpretations by subsequent authors, and as a result, countless Grail novels were written over the next half-century. Thus, the story of King Arthur was gradually restructured around the Grail, evolving into a historical narrative of importance rivaling that of the sacraments.
The fact that Chrétien himself titled this story “The Story of the Grail” demonstrates that the Grail lies at the very heart of these mysteries. So what exactly is the Grail (Graal; English: Grail)? Although it is commonly translated into Korean as “Holy Grail,” strictly speaking, “Holy Grail” refers to the “Saint Graal”—a concept imbued with literary and Christian connotations—and is therefore not an entirely accurate translation. If we simply define the Graal as the “Holy Grail,” the quest for the Graal ceases to be a mysterious scene that transcends any questions. Therefore, in many cases, it is more appropriate to refer to it by its original name, “Graal.”
Before Chrétien, “Graal” was used as a common noun rather than a proper noun. Although not widely used, it appears in the form “gradalis” in a Latin document dating from around 1010, and corresponding forms have been identified in Provençal (“grazal/grasal”) and Catalan (“greal/grialia”). There are also examples in Northern French dialects where the term was used to refer to a vessel used for entertaining guests—a vessel large enough for two people to share a meal. In short, the original “Graal” appears to have been a common noun referring to a fairly large vessel used for dining.
This point is also confirmed in Chrétien’s account. When the Grail is first mentioned in the Grail Procession, it appears as a common noun accompanied by the indefinite article, and the hermit whom the protagonist meets in the forest says, “Do not think that it contained eels, conger eels, or salmon.” In other words, the vessel itself implies a considerable size. However, Chrétien’s description does not stop there. He states that the vessel is “made of pure gold” and “set with the most precious and valuable gems from land and sea in various shapes,” and that it emits a radiance more brilliant than light itself. According to the hermit’s explanation, it contains the Holy Eucharist, and had the Fisher-King asked about it properly, he would have been healed. In other words, Chrétien’s text reveals the process by which the Grail gradually transforms from a common noun into a specific object shrouded in mystery.
So where did the Grail referred to by Chrétien originate? Since it is difficult to believe that he conceived it entirely on his own, it is important to identify the archetype he drew upon. Uncovering the true nature of the Grail will help solve the various mysteries surrounding the Grail tales. Consequently, a significant portion of research on Grail literature has been devoted to determining the Grail’s origins. These discussions do not point to a single cause; the issue is complex because it concerns not only the origin of the Grail itself but also that of the various motifs comprising the Grail tales, and because it requires reference not only to Chrétien’s work but also to subsequent Grail novels. Generally, the discussion is divided into three main strands: Celtic mythological origins, Christian origins, and mystical and ritual origins.
First, considering that the Arthurian legends stem from remnants of Celtic mythology, the Grail story may also have Celtic origins. In fact, elements corresponding to nearly all major motifs—such as the Grail, the spear, the Fisher King, the wasteland, and the question that must be asked—can be found in Welsh and Irish legends. For example, the Grail corresponds to the “vessel of abundance” that appears in various Celtic traditions in the form of a horn, a basket, a cup, or a plate. Chrétien also describes a procession of the Grail passing by whenever new food is served at the Fisher King’s table, and in many subsequent Grail novels, the scene of the Grail wandering from table to table, serving up sumptuous feasts, is repeated. The Bloody Lance serves as a marker of the Otherworld (Autre Monde) and a symbol of kingship; it is characterized as a destructive and vengeful weapon, often depicted as being engulfed in flames or stained with crimson blood. In Chrétien’s text, the Bloody Lance is described as a weapon that brings destruction to the Kingdom of Logres, and this too can be interpreted as a symbol of the same type. Some view the Fisher-King as corresponding to Bran from Welsh mythology or Nuadu from Irish mythology; while these deities are associated with the sea or water and symbolize power, life, and fertility, the Fisher-King’s barrenness represents the opposite—namely, sterility. Finally, the motif of “the question that must be asked” finds its prototype in Irish tales concerning visits to the Otherworld. The question “To whom shall the Grail be taken?” is formally similar to the question “To whom shall this cup be given?”—repeatedly asked by the goddess symbolizing sovereignty over the land—and can thus be seen as linked to the sovereignty of the kingdom.
Thus, while the Celtic mythological origin theory provides very interesting material regarding the origins of individual motifs, it has the limitation of failing to demonstrate the organic relationships between them. In other words, the origins of individual motifs alone do not reveal the true nature of the story in which the Grail and the blood-flowing spear form a procession at the Fisher King’s castle and a question must be asked about them.
In an attempt to overcome this limitation, some researchers have sought to reconstruct a fundamental myth that could be considered the archetype of Celtic imagination. Others have viewed the Grail story as a fusion of tales concerning the quest for otherworldly treasures (amulets) and stories of revenge, and have attempted to trace its archetype to various myths within the Indo-European language family. Discussions have also been raised that seek to identify structural relationships among these motifs and explain the components of the Grail procession and Celtic mythological archetypes in light of the common Indo-European triadic function.
Meanwhile, the Grail procession also appears to allude to Christian liturgy. Above all, as seen in the passage stating that the Grail contained the Holy Eucharist, the Grail can be thought of as similar to a chalice or a ciborium. Furthermore, other elements of the procession can be explained in accordance with Christian tradition: the blood-flowing spear is seen as corresponding to the spear of Longinus, the Roman centurion who pierced Christ—that is, the Holy Lance—while the tray corresponds to the Holy Patten.
Viewed in this light, the Grail procession could be regarded as akin to the Eucharistic rite; however, Chrétien’s Grail procession contains quite a few elements that do not align with Christian rituals. Questions remain, such as why a spear appears in the Eucharistic liturgy, why those carrying the chalice or paten are women, and whether the repeated back-and-forth of the Grail procession before the Fisher King’s table signifies that the Eucharistic liturgy is repeated consecutively. Although similarities to the Byzantine Liturgy of the Presanctified Gifts or the Eucharistic liturgy for the sick have been pointed out, these arguments have not gained much traction.
In addition, the artistic tradition, the tradition of the Church Fathers, Jewish traditions, and the circumstances of the Latin Kingdom in Jerusalem at the time have been cited as evidence supporting the Christian origins of the Grail. However, these theories all focus solely on the Grail and the Grail Procession, failing to explain the other elements that make up the entire narrative. For example, the question regarding the Grail that restores the Fisher-King, or the prophecy that the blood-stained spear foretells the downfall of a kingdom, are difficult to understand solely within a Christian context.
Therefore, scholars who argue for the Grail’s Christian origins view elements such as the Grail and the spear as Christian motifs, but believe they were fictionalized by borrowing from Celtic folklore. Conversely, there is also the argument—which is more persuasive in light of the trajectory of literary history—that Grail literature is not a superimposition of Celtic traditions onto Christian rituals, but rather a transformation of Celtic traditions within Christian culture.
Furthermore, attempts to understand Celtic traditions in contrast to Indo-European traditions have gradually expanded the scope of research seeking the origins of the Grail. This perspective, which seeks to discover archetypes of universal thought and imagination in the Grail stories that transcend any specific religion or mythology, is commonly referred to as perennialism; perennialists believe that a primal tradition has been mysteriously transmitted throughout human history. They interpret the Grail stories as narratives concerning the transmission of such mysteries and seek to elucidate the content of those mysteries.
From this perspective, a wide variety of hypotheses have been proposed, including the claim that a mystical tradition originating from the nature worship and rituals of the Aryans has been passed down; similarities in the sun myths of northern peoples following the Ice Age; the influence of Shi’a doctrine within Islam; the traditions of the Cathar heresy; the transmission of Hermetic texts; and Persian alchemy. Some of these arguments were developed based on scholarly accounts widely recognized as having inspired T. S. Eliot’s poem “The Waste Land.”
However, even if one acknowledges the existence of certain archetypes or esoteric traditions underlying universal human thought and imagination, discussions regarding their specific origins often lack persuasiveness. If one views such archetypes as part of the collective unconscious and assumes that esotericism does not conflict with orthodox religion, linking the Grail’s origin to a specific esoteric tradition risks misrepresenting the true nature of the Grail. Therefore, discussions regarding the Grail’s esoteric origins tend to fall into the realm of subjective speculation as long as they presuppose a vague, universal tradition.
Such discussions regarding the Grail’s origins have, in turn, offered various possibilities for interpreting the “Grail story” itself. If we view this work—like Chrétien’s other works—as a story in which the protagonist seeks to attain a certain ideal, then the nature of the values or the ideal human being he pursues depends on the significance of the Grail quest.
For example, those who view the Grail as a Christian relic—or at least as something that has been sanctified—interpret the “Grail story” as a narrative in which the protagonist, Perceval, comes to realize the truth of the Gospel through his quest for the Grail and thereby achieves true Christian chivalry. On the other hand, those who view the Grail as a symbol of a specific mystery interpret this work as a story depicting the process of initiation into that mystery or the conversion from pagan mystery cults to orthodox Christianity.
However, even though the Grail quest forms the core of the work, it is not the whole story. To fully understand Chrétien’s final, unfinished work, it is necessary to examine its overall structure. Not only is the conclusion of this work unwritten, but the composition of the written sections also exhibits puzzling aspects. Following the prologue, the first half unfolds as the story of Perceval, while the second half tells the story of another knight, Gawain; on the surface, the two halves appear to be unrelated.
In particular, the structure—in which a single episode of Perceval’s encounter with a hermit is inserted amidst Gawain’s adventures, only to return to Gawain’s story—emphasizes the work’s imbalance and disjointedness. This structure is difficult to reconcile with the coherent narrative development seen in Chrétien’s earlier works. Furthermore, in terms of length, while his earlier works generally ran around 7,000 lines, ‘The Story of the Grail’ exceeds 9,000 lines and remains unfinished—a fact that was also considered peculiar.
While there was once debate over whether the “Gobain” section and the passage where Perceval meets the hermit were forgeries, the prevailing view today is that they all form part of the same work. This is because the “Gobain” section also displays Chrétien’s characteristic refined style, and the dichotomous structural form itself is a pattern commonly found in his other works.
Chrétien’s dichotomous structure can be understood in light of his other works. Generally, his works appear to depict the protagonist triumphing over a series of adventures to reach some ideal; however, such victories are merely provisional, as new conflicts emerge, prompting the protagonist to plunge back into adventure and achieve true victory by resolving these issues. Viewed in this context, the “Perceval” section resembles the first halves of his earlier novels and corresponds to the protagonist’s initial journey toward achievement.
The fact that Perceval is recognized as a knight of such excellence that he can be compared to Gauvain, the greatest knight at King Arthur’s court, demonstrates that he has achieved his original goal of “becoming a knight.” However, at the very moment this initial achievement is realized, it is revealed to be superficial or incomplete, necessitating a new beginning for the story. While in other works the motivation for this fresh start stems from love or marriage, it is characteristic of this work that the motivation lies in the failure of the Grail quest.
This suggests that “The Grail Story” raises issues that go beyond those of a simple wedding novel. In other words, the protagonist’s ultimate fulfillment will be achieved in connection with the Grail quest; therefore, to understand the work as a whole, one must consider the broader context centered on the Grail quest.

The Correspondence Between the First and Second Halves of the “Grail Story” and the Issue of Incompleteness

If we follow a binary structural format, the second half of the “Grail Story” should proceed in a direction that resolves and completes the unresolved elements of the first half. This perspective holds that the remaining narrative should unfold with Perceval making amends for his failure, restoring the Fisher King through questions related to the Grail, and bringing prosperity back to the wasteland. However, in reality, the adventures of Gauvain that appear in the second half not only proceed independently of Perceval’s story but also unfold in such a complex manner that it is difficult to find a consistent meaning within them. For this reason, the “Gauvain Cycle”—despite the scholarly view that Chrétien himself intended it as the second half of ‘The Grail Story’—has been regarded as an early draft of an unfinished manuscript that was not sufficiently polished. Consequently, this section has received little scholarly attention and has primarily been interpreted in light of the “Percival” section. For example, in some interpretations, Gobain is highly regarded as a model embodying the chivalric perfection that Percival must attain, while in others, he is disparaged as a figure revealing the limitations of secular chivalry—which, unlike Percival’s open-ended potential, offers no possibility for further development.
However, as a closer reading revealed the close correspondence between the “Percival” and “Gobain” sections, the “Gobain” section began to be reexamined as a crucial clue to understanding the work as a whole. The most striking correspondence between the two sections can be found in the two castles: the Castle of the Grail and the Castle of Wonders. Both castles possess elements reminiscent of the afterlife, and at each location, the protagonists encounter their ancestors or figures who remind them of their ancestors. Furthermore, both castles are associated with the motif of restoring wastelands, and correspondences that are difficult to dismiss as mere coincidence are found in other detailed motifs and descriptions as well. Furthermore, the scene in the middle of the “Gobain” section, in which Perceval meets a hermit in the forest, was once treated as a forgery or an interpolation; however, it has been pointed out that this scene actually forms a clear, intentional contrast with the scene where Perceval first meets the knights in the forest near his mother’s home.
Many recent interpretations approach the work through these correspondences between the first and second halves. Particularly intriguing is the hypothesis that, based on these correspondences, it may be possible to infer the work’s original, complete form. For example, in addition to the correspondences mentioned earlier, intentional contrasts are also found in the episodes involving Borfer and Escavalon, as well as in the so-called “Pieta”—the episode in which young women (Perseval’s cousin and Greoras’s lover) are overcome with grief as they surround a dead or dying knight. This suggests that attempts to reconstruct the work can be made based on these correspondences. Viewed in this light, Gauvain’s story serves to mirror that of Perceval, and it is plausible to hypothesize that the entire work forms a symmetrical structure centered on the hermit’s episode—namely, “Perceval–Gauvain–the hermit–Gauvain–(Perceval)”—culminating in the meeting between Perceval and Gauvain.
From this perspective, some argue that the “Grail Story” is, in fact, complete even in its current state. That is, the work is either complete in the form that survives today, or, even if it is incomplete, the loss amounts to no more than a few missing pages from the end of a completed manuscript. Of course, to view the story as ending inconclusively requires an interpretation that goes beyond the level of a simple plot summary. For example, if we interpret Perceval and Gauvain as humans who, in a state of original sin, come to realize God’s redemption through a grace-filled event and attain salvation, it is natural for the story to conclude without the protagonists’ adventures being fully resolved—since while God’s grace and redemption are timeless events, human life continues within the realm of unfinished time. Alternatively, from the perspective that “The Grail Story” is not a straightforward adventure tale but rather a rhetorical device employing the form of a novel, since the Grail represents the unattainable source of meaning, the work’s unfinished form can be interpreted as a complete form that reveals the inexhaustibility of meaning.
Ultimately, the interpretation of ‘The Grail Story’ as a whole remains within the realm of incomplete hypotheses, never reaching a definitive conclusion. Many of the story’s enigmatic elements clearly serve as indicators demanding interpretation, yet no single interpretation fully satisfies that demand. Consequently, subsequent authors attempt to “elucidate” the narrative, some focusing on the origin of the Grail and others on the conclusion of the protagonists’ adventures. In other words, the Quest for the Grail can be understood as an attempt to answer the two questions that lie at its heart—to whom is it being brought, and where does it come from? The ‘Grail Story’ is a significant work not merely because of how it can be interpreted, but because it has become an inexhaustible source of meaning.

Subsequent Grail Novels

In the half-century following ‘The Story of the Grail’, numerous Grail novels were produced. ‘Parzival’ (early 13th century) by the German poet Wolfram von Eschenbach—which has already been translated and introduced in Korea—is a prime example of a unique adaptation of ‘The Story of the Grail’. In France, subsequent Grail novels developed along two main lines: on the one hand, there was a series of verse continuations that sought to pick up where Chrétien left off and unravel the mysteries within the context of the British legend; on the other hand, various prose works emerged that sought a Christian interpretation of the Grail after Robert de Boron had defined it as a Christian relic. Of these two directions, the latter—the tradition of interpreting the Grail as a Christian relic—became the mainstream.
When estimating the approximate chronology and lineage of these works, the following sequence is generally accepted: First comes Chrétien’s ‘The Story of the Grail’ (c. 1185), followed by the short version of the First Sequel, Robert de Boron’s ‘Joseph’ and ‘Merlin’, the Second Sequel, ‘Perceval in Prose’, ‘Perlesvaus’, ‘La Queste del Saint Graal’, the long version of the first sequel, the third sequel, the fourth sequel, and ‘L’Estoire del Saint Graal’ (circa 1235). Among the verse sequels, the “Elucidation” and “Bliocadran”—which serve as prologues added later—are believed to have been written in the late 13th century.
Even among the verse sequels, a gradual Christianization of Grail-related motifs can be observed in works that were originally secular adventure tales. The work that marked the most significant turning point in this development is Robert de Boron’s ‘Estoire dou Graal’, written about twenty years after Chrétien’s ‘Story of the Grail’. In this work, the Grail is presented for the first time as the chalice used in the Last Supper—the vessel that held the blood shed by Jesus Christ on the cross, that is, the Holy Grail. According to Robert, the protagonist is Joseph of Arimathea from the Bible, and the narrative—in which he takes this cup to the distant West and awaits a descendant to inherit it—links the origin of the Grail to a holy relic.
This identification of the Grail with a holy relic also brought about several changes in narrative form. First, with the exception of a single poetic manuscript, ‘Joseph’ is primarily transmitted in prose form, and subsequent works seeking a Christian interpretation of the Grail tend to be written entirely in prose. While this shift to prose is not unrelated to the historical trend of expanding the readership, it can also be understood as a literary device intended to guarantee the story’s authenticity by adopting the prose style commonly used in religious writings of the time. Furthermore, at the end of ‘Joseph’, Robert foreshadows a serialized structure, suggesting that an intermediate narrative is needed to bridge the historical gap between the Sacraments and Britain. Accordingly, ‘Joseph’ reveals the intention to present the Grail narrative as a single sacred history through a serialized structure that leads from the Merlin tales to the original Grail tales set in Britain. This approach reinforces the narrative’s authority and aligns with the phenomenon of subsequent Grail novelists gradually becoming anonymous.
It appears that Robert sought to trace the origins of the Grail back to the Sacraments and to build a spatiotemporal bridge between the Sacraments and the tales of Britain. However, since the third tale—said to have been written by Robert himself—has not survived, it is unclear exactly how he intended to conclude the Grail quest. The questions of how the Grail quest would unfold after the Grail was defined as the Holy Grail, and what meaning the “quest” for the Grail could still hold, remained challenges for the entire subsequent Grail tradition to resolve.

The Religious Significance of the Grail and Early Interpretations

Stories that ascribe religious significance to the Grail quest by identifying the Grail as the Holy Grail can be found in ‘Perlesvaus’ and ‘La Queste del Saint Graal’. These works are based on an interpretation that reads the knights’ adventures not as mere battles of lances and swords, but as a journey imbued with spiritual meaning. In particular, some manuscripts of ‘Perlesvaus’ include ‘Perceval’—apparently written by a later author—alongside the texts of ‘Joseph’ and ‘Merlin’; this is often referred to as ‘Perceval en prose’ or, after the name of its owner, ‘Didot-Perceval’. This work was an attempt to conclude Chrétien’s unfinished Grail tale by drawing on the plot of the “Second Sequel,” based on the framework established by Robert’s earlier works. However, defining the Grail as the Holy Grail here did not alter the core of the narrative’s development but remained largely limited to presenting a spiritual interpretation.
For this reason, such interpretations remain sporadic. The quest for the Holy Grail runs through the entire work; it is precisely in this “quest for the Holy Grail” that the adventures consistently take on spiritual significance and the meaning of the Grail deepens. One day, the chaste knight Galahad appears at King Arthur’s court, and the full-fledged quest for the Holy Grail begins. In this tale, where countless knights fall in vain along the way and only a select few come close to the Holy Grail, every adventure is read as a metaphor for a spiritual struggle. The Grail is presented not merely as a relic of the Eucharist or the Passion, but as a symbol representing the presence of God, faithfully reflecting the Christian worldview that views life as a journey from physical existence in this world to the spiritual realm. In particular, the “Mystery of the Grail,” revealed only in the final stage of the quest, is depicted as a vanishing point through which humanity’s spiritual journey opens onto the infinite afterlife.

The Lancelot-Grail Cycle and “The Death of King Arthur”

It is interesting to note that the “Quest for the Holy Grail,” which pursued such religious ideals, forms a cycle with “Lancelot,” which extolled secular courtly culture. “Lancelot” expands upon Chrétien’s “Lancelot of the Chariot,” narrating Lancelot’s journey from birth to becoming the greatest knight, and presenting the love between Lancelot and Queen Guinevere as the ideal of courtly love. The contrast between the secular ideal of ‘Lancelot’ and the religious ideal of ‘The Quest for the Holy Grail’ leads the story to its conclusion, ‘La Mort du Roi Arthur’ (‘The Death of King Arthur’). Whereas in earlier works by Geoffrey or Wace, Arthur’s death was depicted as a mere historical event, it is now portrayed as the tragic end of an entire world. On the one hand, with the conclusion of the Quest for the Holy Grail, the wonders beyond the court disappear and no further adventures occur; on the other hand, the ideal of courtly love is revealed to be adultery, causing internal fractures that lead to the collapse of King Arthur’s kingdom from within and without. This conclusion illustrates the process by which the courtly ideology of the time converged with the ideology of the Church.
In short, Arthurian literature follows a narrative arc that begins with the expansion of ‘Lancelot, the Knight of the Chariot’ and ‘The Story of the Grail’—based on Chrétien’s incomplete fragments—and culminates in ‘The Death of King Arthur’. From that point onward, as a linear progression of the story becomes impossible, the narrative remains within legendary time, either repeating similar characters and events or returning the story to a time before Arthur.
Through this process, the so-called “Vulgate” series was created by adding “L’Estoire del Saint Graal”—a further development of “Joseph”—and “Merlin” to Chrétien’s stories. This Vulgate—the definitive version of the Arthurian legends widely accepted as the popular edition—is a five-part series compiled between 1215 and 1235, representing the culmination of the structure Robert had intended. Here, the Arthurian legend traces its origins back to the history of redemption through the Grail, and once the quest for the Holy Grail is complete, it extends all the way to the end of the world. This process of reinterpreting the remnants of ancient Celtic mythology as the history of humanity’s salvation has served as a rich source of meaning, enabling a half-century of diverse interpretations. Regardless of the explanations added by subsequent authors, what ultimately draws readers back to that initial fascination is the enduring charm of the Grail scenes depicted by Chrétien.
