The Power of History and Memory

What This Theme Explores

In A Discovery of Witches, The Power of History and Memory asks how the past—archival, ancestral, and biological—dictates who people are and what futures they can choose. For Diana Bishop, history is both a professional method and a personal inheritance she has tried to refuse, while for Matthew Clairmont, memory is a centuries-long burden that governs instinct and allegiance. The novel treats archives and recollection as living forces: libraries, bloodlines, and DNA become repositories that press on the present. Ultimately, the story insists that only by entering the past—intellectually, emotionally, and literally—can characters dismantle prejudice, accept themselves, and reimagine what’s possible.


How It Develops

At first, history functions as Diana’s shield. Her life in Oxford is arranged around the Bodleian’s order and routines; scholarship lets her believe she can choose reason over magic. When Ashmole 782 surfaces, the past stops being a controlled object of study and becomes an unruly agent: a bewitched text selects her, collapsing the tidy distance between observer and subject.

As the plot deepens, history turns from intellectual interest to existential threat. Diana’s investigation into her parents’ deaths exposes how incomplete, inherited narratives sustain self-deception, while Matthew’s disclosures—about earlier loves, violent losses, and the ancient covenant—show how personal memory fuses with institutional history to police desire. In Matthew’s lab, genetics recasts history as data, revealing that memory isn’t only conscious recollection but a biological ledger of origin and decline; bodies themselves become archives.

By the end, history is not merely consulted but inhabited. Timewalking, anchored by intimate artifacts, renders the past a terrain to be traversed for survival. Revelations ripple backward and forward—Diana learns her father bewitched Ashmole 782 to reach her across centuries—proving that the past actively engineers the present. The Knights of Lazarus further demonstrate how old orders still wield power; oaths sworn long ago continue to shape choices, loyalties, and the possibilities of love.


Key Examples

  • Diana’s Profession and the Bodleian: Diana studies the moment when “science supplanted magic,” curating a life where scholarship keeps witchcraft at bay. Her haven, Oxford’s Bodleian, turns on her when Ashmole 782 arrives, forcing her to acknowledge that the past she analyzes is also the one that claims her (Chapter 1-5 Summary). The library’s rituals and rules cannot contain a manuscript that insists on personal recognition.

  • Matthew’s Lived History: As a fifteen-hundred-year-old vampire, Matthew’s memory is embodied experience, not abstraction; trauma and allegiance encoded across centuries produce his vigilance, secrecy, and ferocity. His familiarity with figures like Charles Darwin and the sixteenth-century Old Lodge illustrates how history is domestic for him—built, inhabited, and defended—so his choices are inseparable from long-remembered losses. The result is a character whose present is perpetually negotiated with ghosts.

  • The Burden of Family Lineage: Diana’s identity as a Bishop witch makes her a living continuation of a notorious archive, from Bridget Bishop’s execution at Salem to her parents’ mysterious deaths. Characters like Gillian Chamberlain weaponize this lineage to police Diana’s choices, proving that ancestry can be used as both explanation and threat. When evidence complicates Diana’s assumptions about her parents, the narrative dramatizes how revising the past is necessary to claim an honest self (Chapter 6-10 Summary).

  • The History of the Species: The Congregation’s covenant codifies ancient prejudice into law, dictating who may love whom and where creatures belong. This legal history structures everyday life, showing how old rules outlast their original context to reproduce segregation in the present. Daemons like Agatha Wilson, lacking a recorded lineage, underscore the theme’s counterpoint: without shared memory, belonging becomes precarious and identity unstable (Chapter 26-30 Summary).

  • Timewalking as Praxis: The decision to travel to 1590 literalizes the thesis that the past must be entered, not just interpreted. The required anchors—a manuscript of Doctor Faustus from Christopher Marlowe, one of Ysabeau de Clermont’s earrings, and a silver chess piece—bind memory to material culture, turning artifacts into passageways. The move confirms that objects can carry emotion, allegiance, and information potent enough to alter destiny (Chapter 41-43 Summary).


Character Connections

Diana Bishop: Diana’s arc reframes scholarship as courage. Her photographic memory and training predispose her to respect evidence, but she must learn that personal history counts as evidence, too. Integrating her lineage with her discipline transforms memory from a source of shame into a resource: she becomes a historian capable of revising the record—including her own—rather than hiding behind it.

Matthew Clairmont: Matthew embodies history as burden and vocation. Centuries of remembrance produce reflexes—protection, secrecy, suspicion—that keep him alive but also trapped in cycles of fear and retribution. His genetics research, an attempt to read history through bodies, extends his fixation with origins, evolution, and extinction, revealing both the promise and peril of treating memory as data: it can guide care across species, but it can also harden hierarchies when interpreted through fear.

Ysabeau de Clermont: Ysabeau’s grief makes memory hereditary; the murder of Philippe locks her perception of witches in a single searing moment. Her interactions with Diana show how unexamined trauma becomes policy, turning pain into prejudice. As she begins to recognize Diana’s integrity, the narrative suggests that even the oldest memories can be recontextualized—not erased, but integrated into a more capacious understanding.

Peter Knox: Peter Knox manipulates the archive. He marshals occult lore and Diana’s family history to intimidate, demonstrating how selectively telling the past can control the present. His ambition reframes memory as weapon—a reminder that whoever narrates history often governs its consequences.


Symbolic Elements

Ashmole 782: The bewitched manuscript is the novel’s master symbol, an origin text everyone seeks to interpret and control. Its volatility—appearing, vanishing, responding to Diana—insists that history is not neutral; truth arrives entangled with need, fear, and desire.

The Bodleian Library: A sanctuary of order and preserved memory, the Bodleian symbolizes history’s authority and allure. When its catalog yields an impossible book, the setting exposes the tension between custodianship and discovery: control must give way to encounter.

Ancient Houses (Sept-Tours, the Old Lodge): These spaces are archives of stone—habitable records of love, loss, and loyalty. To enter them is to enter a family’s memory, where corridors store vows as surely as documents do.

DNA and Genetics: In Matthew’s lab, DNA functions as a biological manuscript, encoding the story of a species’ past and possible futures. The double helix becomes a mirror to Ashmole 782: both are texts that, once read differently, could disrupt entrenched hierarchies or confirm them.


Contemporary Relevance

The novel’s insistence that we reckon with the past to live responsibly now resonates in debates over historical injustice, identity, and belonging. It shows how inherited narratives—national, familial, institutional—can either imprison or empower, depending on whether they are interrogated or accepted uncritically. By making archives into characters and artifacts into doorways, the story argues that memory is an ethical practice: we must curate it honestly, acknowledge trauma without fetishizing it, and revise the record to make room for the future we choose.


Essential Quote

“During one of the island’s rebellions, her fellow plantation owners, who had figured out what she was, decided to get rid of her. They sliced off Louisa’s head and cut her body into pieces. Then they burned her and blamed it on the slaves.” (Chapter 36-40 Summary)

This account collapses historical atrocity into personal memory, showing how violence circulates through both private grief and public scapegoating. It explains Matthew’s present-tense ferocity while indicting the mechanisms—prejudice, rumor, power—that turn history into justification for more harm. The quote crystallizes the theme’s claim: the past is not past; it lives on in the bodies, choices, and fears of those who remember—and those who are made to forget.
