Summary

Chapter 22, titled “The Tale of Sir Dagonet and Sir Constantine; or, the Quest for the Holy Grail; or, the Very Last Adventure,” opens with Sir Dagonet, Camelot’s fool and the lowest-ranked knight, being the first to suspect that the coming Grail quest is not a blessing but a portent of disaster. Dagonet’s life experience has taught him that the worst catastrophes often arrive disguised as miracles, and he privately concludes that the glorious Grail will mark the end of Arthur’s age and the beginning of the end of everything.

The chapter then recounts Dagonet’s backstory. He grew up in the flooded Fenlands, a marshy region of bogs and meres. He came to Camelot with a troupe of traveling minstrels, performing a ring trick before King Arthur. Dagonet made Arthur’s signet ring disappear and reappear in increasingly absurd places, finally producing it from an orange that his assistant, a learned dwarf named Oswald, had snatched from him. The knights were delighted, and Dagonet was made Camelot’s new fool. However, his straight-faced manner was not an act; Dagonet suffered from mental illness, experiencing nameless fears, rages, and black miseries. He found solace in juggling, which he saw as a glimpse of a clean, eternal order beyond the chaos of the world. Arthur later knighted Dagonet, giving him full honors, though Dagonet never understood why. The chapter suggests Arthur may have seen a reflection of himself in the low-born fool, or perhaps intended to teach the other knights humility.

On Whitsunday in the twenty-third year of Arthur’s reign, a marble block bearing a sword floats in the river Brass. Arthur declares he will not eat until he sees a marvel. The knights rush to the riverbank. Lancelot declines to try, saying the sword is not for him. Gawain attempts and fails, as do Percival, Bors, Gareth, and Palomides. A boy in white samite then enters the Great Hall, sits in the Siege Perilous—a chair that had previously killed a knight who dared to sit in it—and golden letters appear naming him Sir Galahad. Galahad claims the sword from the stone, and later the Holy Grail appears in the hall, healing wounds and providing each knight with his desired food and drink. Even Dagonet feels a moment of peace, though he notices that Galahad himself seems unmoved.

Arthur, surprisingly, refuses to join the Grail quest, citing his age and duties as king. A rumor spreads that whoever finds the Grail will succeed Arthur as king of Britain, since Arthur and Guinevere have no heir and his only relatives are his half-sisters and an illegitimate son. The knights form adventuring parties, and Constantine, a tall but unremarkable knight, invites Dagonet to quest with him. Dagonet initially refuses, but Constantine persists, and they set out together. On the fourth day they reach Sir Turquine’s castle, Blackfast. Constantine is unhorsed and injured in combat, and Dagonet surrenders without a fight.

Character Development

Dagonet emerges as the chapter’s central figure, a “lazy Cassandra” who sees the truth but does not speak it. His mental illness is portrayed with sympathy, and his juggling is presented as a coping mechanism that gives him a sense of order. His knighting by Arthur is ambiguous—possibly a cruel joke, possibly an act of recognition. Dagonet’s decision to accompany Constantine, despite his initial resistance, shows a reluctant willingness to engage with the world.

Constantine is introduced as a kind, affable knight who is underestimated by everyone, including himself. His persistence in asking Dagonet to join him reveals a gentle stubbornness and a desire to do good, even if he assumes others see him as a token appointment.

Arthur is shown in a new light. His refusal to join the Grail quest is puzzling to Dagonet and others, and the chapter hints that Arthur may be aware of the succession crisis. His earlier decision to knight Dagonet is revisited, suggesting a complex, perhaps self-reflective side to the king.

Lancelot declines the sword, a rare act of humility or perhaps premonition. His comment that the sword will one day wound Gawain foreshadows future conflict.

Galahad is presented as a perfect, almost inhuman figure. He is handsome, confident, and utterly unmoved by the Grail’s appearance, which contrasts with the emotional responses of everyone else. His arrival shifts the center of gravity at Camelot, making even Arthur and Lancelot seem like minor characters.

Themes, Symbols, or Motifs

Miracle as omen of disaster: Dagonet’s belief that the Grail’s beauty signals catastrophe is a central theme. The chapter frames the quest as the beginning of the end of Arthur’s age.
The fool as prophet: Dagonet, the lowest-ranked knight, is the only one who suspects the true nature of the quest, yet no one would listen to him.
Madness and mental illness: Dagonet’s struggles are depicted with nuance, and his juggling is a symbol of his attempt to impose order on chaos.
Juggling as cosmic order: Dagonet sees his art as “the movement of the spheres writ small,” a glimpse of eternal order.
Worthiness and divine judgment: The sword in the stone and the Siege Perilous test worthiness, and the chapter references the earlier disaster of the Holy Lance as a warning.
Succession crisis: The rumor that the Grail finder will become king highlights the political stakes and the lack of a clear heir.
Fractures in the Round Table: The chapter mentions the feud between Gawain and Percival’s families, and the competitive, cliquish formation of questing parties.
The lowly raised to knighthood: Dagonet’s knighting and his role as a questing knight echo the theme of unexpected elevation.

Why This Chapter Matters

This chapter is pivotal because it launches the Grail quest, a central event in Arthurian legend, and introduces Galahad as the prophesied hero. It also deepens the characterization of Dagonet, transforming him from a comic figure into a tragic, perceptive observer. The chapter establishes the political and spiritual stakes of the quest, linking it to the succession crisis and the impending end of Arthur’s reign. Arthur’s refusal to participate and Lancelot’s refusal of the sword signal a shift in the old order, while Galahad’s arrival makes everyone else feel like minor characters. The chapter’s title, “The Very Last Adventure,” foreshadows the finality of what is to come, and Dagonet’s surrender at Blackfast suggests that the quest will not be a triumphant one for the lowly.

Study Questions and Answers

1. Why does Dagonet suspect that the Grail quest will bring disaster, and how does his backstory inform this suspicion?

Dagonet’s life has taught him that “the worst disasters come dressed as miracles.” His upbringing in the Fenlands, his mental illness, and his experience as a fool have given him a cynical, clear-eyed view of the world. He sees the Grail’s beauty as a sign of impending catastrophe, and his role as a “lazy Cassandra” means he perceives the truth but does not act on it. His backstory of being raised from the lowest station to knighthood also makes him sensitive to the precariousness of fortune.

2. How does Arthur’s refusal to join the Grail quest complicate his character, and what does the rumor about the succession suggest about the political situation?

Arthur’s refusal is surprising because he is pious and loves adventures. The chapter suggests his reasons—age, duty, making room for the young—do not ring true. The rumor that the Grail finder will become king implies that Arthur knows he has no heir and that the quest is a divine contest for the throne. This complicates Arthur’s character by showing him as a ruler aware of his own mortality and the fragility of his legacy, rather than the confident king of earlier tales.

3. What is the significance of Galahad’s arrival and his reaction to the Grail?

Galahad’s arrival shifts the center of gravity at Camelot, making everyone else feel like minor characters. He is the prophesied hero who can sit in the Siege Perilous and draw the sword. However, his reaction to the Grail is notably cold—he feels nothing while others are transported. This suggests that Galahad is a perfect, almost inhuman vessel for divine purpose, and his lack of emotion may foreshadow the impersonal nature of the quest and the end of the human, flawed era of Arthur’s court.
