Archimedes: The Cat Who Crosses Boundaries

Overview

Archimedes is the dark-gray, green-eyed department cat of Cambridge’s Analytic Magick faculty. He appears in Hell shortly after Alice Law and Peter Murdoch perform a temporally specific sacrifice in the Fields of Asphodel. Although he was alive and well in Cambridge that same morning (Chapter Two), the ritual summons him to the underworld—a fact that startles Peter. Archimedes is not a typical pet; he belongs to no one, expects respect (eye contact), and moves with the quiet authority of a creature that “can cross boundaries” (Chapter Two). Throughout the journey, he acts as an intermittent guide, a source of comfort, and ultimately a sacrificial victim whose remains Alice repurposes for her final confrontation with the Kripkes.

Plot Role

Archimedes does not advance the plot through dialogue or complex schemes, but his presence shapes key events:

Summoned as a false lead: The sacrifice meant to locate Professor Grimes instead brings Archimedes, suggesting that the cat’s connection to the department is more temporally rooted than any object (Chapter Two).
Guide to the Court of Desire: He leads Alice and Peter to the decaying student center where Shades are trapped in addictive loops (Chapter Nine).
Warning of danger: Returning injured with blood streaked across his fur, Archimedes confirms the existence of the bone-things—a threat few sojourners ever recorded (Chapter Eight).
Unwitting betrayer: In Chapter Eighteen, Archimedes exposes Alice and Peter’s Liar Paradox pentagram to Elspeth, causing their ejection from her barge. This action forces the pair to continue on foot into more dangerous courts.
Distraction in battle: During Alice’s climactic duel with Nick Kripke, Archimedes leaps onto Nick’s head, giving Alice the split second she needs to complete her necromantic spell (Chapter Thirty-One).
Sacrifice and repurposing: In Chapter Twenty-Nine, Archimedes is caught in a Kripke trap and bled to death; Alice later uses his bones to craft armor and weapons (Chapter Thirty), and his death steels her resolve.

Motivations and Traits Shown Through Actions

Archimedes’s behavior is inferred from his actions since he cannot speak. He appears driven by instinct, curiosity, and a form of loyalty that is never openly declared:

Independence: He refuses to be petted unless acknowledged first, circling the sacrificial fire with cool detachment (Chapter Two). His approval is never assumed.
Bravery under duress: Despite being injured by bone-things (Chapter Eight), he continues to accompany Alice into the more dangerous courts. He later attacks a Kripke directly, a suicidal act of distraction.
Vulnerability: He trembles against Alice’s side after his injury, and his eyes go wide with panic when trapped in the Kripkes’ snare (Chapter Twenty-Nine). These moments humanize him without anthropomorphizing.
Practical orientation: He does not linger over philosophical debates. When he wants to move, his tail swishes; when he is afraid, he hides. His behavior is always immediate, never calculated.

Chronological Arc

The outline and evidence track Archimedes across the following stages:

Arrival (Chapter Two): Summoned inadvertently from the living world. Alice kneels to him, surprised but unsurprised.
Exploration (Chapters Eight–Nine): He scouts ahead, is injured, and later leads the party to the Court of Desire.
Exposure of trick (Chapter Eighteen): He reveals the pentagram to Elspeth, inadvertently sabotaging Alice’s plan.
Death in the trap (Chapter Twenty-Nine): Caught by the Kripkes, he is bled into buckets while Alice watches, unable to save him.
Resurrection? (Chapter Thirty-One): Only two chapters later, Archimedes appears again to distract Nick Kripke. The novel does not explain this inconsistency within the provided outline—it may be a ghost, a manifestation of memory, or a chronological skip. The reader is left to interpret whether the cat who died is the same as the one who attacks Nick.
Final rest (Chapter Twenty-Six): After Peter’s death, Alice meets a wounded Archimedes and sleeps beside him, finding comfort in his presence.

Relationships

Alice Law: The primary bond. Alice speaks to Archimedes as an equal, respecting his autonomy. She scratches his head, lets him sleep against her ribs, and weeps while he is killed. For Alice, he represents a link to a home she may never see again and a source of wordless companionship in the isolating journey.
Peter Murdoch: Peter is pragmatic about Archimedes, using him as a tool (asking if the cat can lead them to Grimes). They share no emotional intimacy; Archimedes never seeks Peter’s touch the way he does Alice’s.
Elspeth Bayes: Archimedes greets Elspeth with a “happy yowling noise” and runs between her legs, showing familiarity. Elspeth in turn scratches his head, and it is Archimedes’s curiosity that uncovers the Liar Paradox pentagram.
The Kripkes: His only adversarial relationship. Archimedes directly confronts Nick Kripke and is killed by the family’s bone-trap, making him an indirect victim of their cruelty.

Key Decisions and Consequences

Decision to follow the summoning: Archimedes chooses to appear when the sacrifice is made. Consequence: He becomes Alice’s companion in Hell.
Exposure of the pentagram: Whether by accident or feline curiosity, Archimedes reveals the hidden pentagram to Elspeth. Consequence: Alice and Peter lose Elspeth’s aid and are stranded.
Attack on Nick Kripke: Archimedes distracts the enemy long enough for Alice to finish her incantation. Consequence: Alice can bind Nick’s soul, a turning point in her battle.
Death and repurposing: His bones become Alice’s armor and weapons. Consequence: Alice gains the material means to fight the Kripkes, and his sacrifice fuels her righteous anger.

Theme and Symbol Connections

Archimedes embodies several of the novel’s core themes, as explored on the themes page:

Memory and identity: He exists outside human memory and expectation. Unlike the Shades who cling to their Cambridge identities, Archimedes has no need for a fixed self; he simply is. His presence near the Lethe (river of forgetfulness) highlights the contrast between intentional forgetting and natural instinct.
Trust and betrayal: The cat who exposes the pentagram is the same cat who distracts Nick. He acts without malice or loyalty in the human sense, which mirrors the arbitrary nature of trust in Hell. See the trust and betrayal theme for more.
Sacrifice and redemption: Archimedes gives his life (whether once or twice) for Alice’s mission. His death is not chosen, yet it is the only pure sacrifice in the novel—untainted by the selfish motives that drive Alice, Peter, or Grimes. This connects to the sacrifice and redemption theme.
The nature of Hell: As a creature who “can cross boundaries,” Archimedes shows that Hell’s rules are not absolute. Animals belong to a different ontological category than human souls, and his movements subtly undermine the rigid structure of the Eight Courts. For more, see the nature of Hell.

Questions and Answers

Q1: How is Archimedes summoned into Hell, and why does it surprise Peter?
A1: Alice and Peter perform a sacrifice of temporally specific foods—cigarettes, Lembas Bread, and tawny port—to call the shade of Professor Grimes. Instead of Grimes, Archimedes appears. Peter is surprised because the cat was alive in Cambridge that morning; the ritual was designed to attract the dead, not the living (Chapter Two).

Q2: What information does Archimedes bring back after his first injury?
A2: He returns with blood streaked across his fur, trembling against Alice. His condition confirms the existence of the “bone-things”—creatures that chase the party and are repelled by Lethe water. No other sojourner’s account mentions these threats (Chapter Eight, Chapter Nine).

Q3: Why does Archimedes expose Alice and Peter’s trap to Elspeth?
A3: The outline states only that “Archimedes exposes the trick” (Chapter Eighteen). It is inferred from his earlier curiosity that he investigates the pentagram out of instinct, inadvertently revealing its location. The text does not assign him a conscious motive.

Q4: Is Archimedes killed in the novel?
A4: Yes, in Chapter Twenty-Nine he is caught in a Kripke trap and bled to death while Alice is frozen. However, in Chapter Thirty-One he appears alive again, leaping onto Nick Kripke’s head. The outline does not explain this contradiction; it may be a ghost, a duplicate, or a chronological anomaly. The reader must interpret whether the cat who dies is the same as the one who attacks Nick.

Q5: What symbolic role do Archimedes’s bones play in the final battle?
A5: After his death, Alice crafts armor and weapons from the cat’s bones (Chapter Thirty). This act transforms his physical remains into tools of resistance, paralleling how the Kripkes use blood and chalk. It also ties into the theme of sacrifice—Archimedes’s body becomes the means for Alice to continue fighting for Peter’s memory. For the full ending, see the ending explained.
