A Treatise of Witchcraft

Alexander Roberts (d. 1620)

The devil’s reach is long, yet his power is limited to the permissions granted by a higher authority. To understand his influence is to recognize the absolute necessity of anchoring one’s faith in God alone.

In Short

This seventeenth-century theological defense of the reality of witchcraft serves as both a moral guide and a case study. The author, a preacher, constructs a systematic argument regarding the existence, methods, and dangers of sorcery, culminating in a detailed, eyewitness account of a local woman’s trial for these crimes. It has endured as a primary historical record, offering a window into the intersection of religious doctrine, communal fear, and the judicial processes of the Jacobean era. It remains a stark, chilling testament to the internal logic of a period that viewed the unseen world as a tangible, lethal threat.

The Story

Advertisement

The narrative begins with a philosophical and theological positioning. The author establishes that magic is not merely a collection of superstitions but a genuine, albeit damnable, art derived from ancient heathens and ultimately orchestrated by the devil himself. He draws upon a wide array of classical and ecclesiastical authorities to prove that witches exist and that their influence, while subject to the supreme will of God, is a real danger to the lives and souls of the faithful.

The argument progresses through several propositions. The author contends that the devil can assume physical form, enter into vocal contracts with men and women, and bestow upon them the power to harm the innocent. He emphasizes that the primary goal of this "hellish art" is the withdrawal of individuals from the worship of God. He argues that even those who use "charming" words or invoke the name of the Lord are merely disguising the devil’s poison with sweetness.

The scope of the text then narrows from the universal to the particular. The author transitions to a "true narration" of a specific case involving a woman named Mary Smith. Mary, the wife of a glover, is portrayed as a woman who, through a formal contract with the devil, sought vengeance against those she perceived as enemies. The account describes the petty triggers that led to her accusations: a dispute over a stolen hen, a disagreement about sweeping a street, and other mundane social frictions.

Following these altercations, the victims—Elizabeth Hancocke and Cicely Balye—report falling into states of physical agony, suffering from mysterious illnesses, and experiencing supernatural visitations by cats and other spirits. The author details the judicial process, noting the "vehement presumptions" and the "voluntary confessions" that solidified the charges against Mary. The arc concludes with her condemnation and execution on the twelfth of January. The author uses this grim outcome as the final proof of the necessity of the law—citing the biblical mandate that a witch shall not be suffered to live—and closes with a fervent plea for the reader to eschew all occult counsel in favor of prayer and the church, warning that any reliance on such dark arts, even in jest or for healing, constitutes a total abandonment of the divine protector.

How It Unfolds

The pedigree of magic The author traces the origins of sorcery back to ancient practitioners, arguing that the devil has always sought to ensnare the curious. He frames the history of magic as a direct attempt to undermine Christian worship through various guises, such as divination and necromancy.

The theological framework A series of propositions establishes the devil's capacity for physical manifestation and his ability to grant powers to human subordinates. The author insists that these harms are only permitted by God to test the faith and patience of his children.

The case of Mary Smith The focus shifts to a concrete local example, detailing how Mary Smith entered into a pact with the devil. This section documents the specific grievances, the curses uttered, and the ensuing physical afflictions of her neighbors.

The judicial conclusion The text recounts the legal proceedings against Mary, relying on witness testimony and her own confession to justify her fate. The narrative concludes with her execution, framing it as a necessary act of social and spiritual purification.

The final exhortation The author concludes by summarizing the dangers of consulting with "cunning" men or women. He provides a final warning that seeking help from sources other than God is a betrayal that leads inevitably to destruction.

The People

Mary Smith, the central figure, is a woman who, driven by malice and social grievances, chooses to enter a formal, vocal contract with the devil. She is depicted as a figure who transforms petty interpersonal conflicts into lethal spiritual wars, ultimately becoming a "bond-slave" to her dark master. Her actions stand in direct opposition to the moral order, and her eventual execution is presented as the inevitable result of her choices.

Elizabeth Hancocke and Cicely Balye appear as the primary victims of Mary’s wrath. Elizabeth, a neighbor, and Cicely, a domestic servant, find their lives upended by sudden, inexplicable illnesses and physical torment. Their suffering serves to validate the author's argument regarding the tangible harm caused by witchcraft. They represent the innocent common folk who are forced to contend with the "hidden mysteries of wickedness."

The author, Alexander Roberts, acts as both theologian and chronicler. He is a man of his time, deeply committed to the belief that the physical world is constantly influenced by spiritual forces. He views himself as a shepherd, writing to the inhabitants of Kings-Linne to guard them against deception. His voice is one of moral certainty; he is motivated by the conviction that to ignore the reality of witchcraft is to invite the devil into the heart of the community.

In Its Own Voice

The author describes the origin of the devil's influence on humanity and the specific nature of his deception:

The Diuell must haue the precedencie, whose schollers both he and the rest were, who followed treading in his steps.

Regarding the danger of those who use holy language to mask their dark practices, the author warns:

Therefore she is the more to be hated, because shee hath abused and taken in vaine that great and glorious name, and professing herselfe a Christian, yet practiseth the damnable Arts of miscreant and vnbeleeuing Heathen.

In considering why God might allow the devil to torment his people, the author reflects on the nature of suffering:

Thus his tentation was a medicine preseruatiue preuenting the disease of his soule, which otherwise hee might haue falne into.

What It's Really About

The central theme is the absolute sovereignty of God over a world where the devil is actively seeking to destroy the faithful. The book argues that witchcraft is a real and dangerous force, not because the witch has independent power, but because they have surrendered their agency to a malevolent intelligence. The underlying questions are not merely about the existence of sorcery, but about the nature of human suffering and the limits of human knowledge. It explores why God permits evil to persist and how a believer should respond when faced with inexplicable misfortune. The text operates on the premise that the physical and spiritual realms are deeply intertwined, and that every action—even a trivial one like sweeping a floor—carries eternal moral weight.

Why Read It Today

Readers interested in the history of ideas, early modern English, or the dark sociology of the witch trials will find this volume deeply compelling. It is not an easy read; the prose is dense, marked by the formal, elaborate style of the early seventeenth century and a heavy reliance on Latin citations and theological jargon. The reader must navigate period attitudes that are profoundly alien to modern sensibilities, particularly regarding the casual acceptance of execution as a remedy for social conflict.

However, the reward for this effort is a vivid, unvarnished look at the mindset of a society defined by its anxieties. The "true narration" of Mary Smith is remarkably intimate, detailing the petty, domestic squabbles that fueled the fear of the supernatural. It is a haunting document because it captures the voice of a man who genuinely believed he was doing God’s work by documenting the mechanics of evil. What stays with you is the chilling realization that for these people, the devil was not a metaphor, but a neighbor. If you can move past the archaic structures and the stern, dogmatic tone, you are left with a raw piece of history that illuminates the fragility of community life when gripped by the terrifying power of belief.
