Cotton Mather

← Encyclopedia

Cotton Mather was a Puritan minister of Boston and the most prolific American author of his age, remembered above all for his writings on witchcraft and the unseen order of spirits he believed pressed against the visible world. He was born in 1663 into the colony’s reigning clerical dynasty — son of Increase Mather and grandson of two of New England’s founding divines — and spent his life at Boston’s Old North Church, preaching, publishing, and laboring to keep a fading Puritan errand alive in a colony that was slipping its moorings.

His learning was genuine and wide. He read the ancient and biblical languages, corresponded with European scholars, championed smallpox inoculation against furious local opposition, and was elected a fellow of the Royal Society — one of the first colonists so honored. The inoculation method itself he learned from Onesimus, a West African man he enslaved, who had undergone the operation in Africa and described it as the common practice of his people. Out of that mind came some four hundred published works, among them the Magnalia Christi Americana (1702), a vast ecclesiastical history of New England written to fix in memory what its founders had attempted. He understood himself as a guardian of that project, and much of his writing has the urgency of a man certain the ground is giving way beneath it.

The reputation that overshadows the rest is the witchcraft. Mather held, as most learned Christians of his century did, that the world was thronged with invisible agents — angels, devils, the souls of the dead — and that these could break into ordinary life. His Memorable Providences (1689) recounted a Boston family’s apparent affliction by witchcraft, and during the Salem trials of 1692 he wrote The Wonders of the Invisible World, a defense of the court’s work composed partly at official request. His exact role is contested ground for historians: he counseled caution about “spectral evidence” — testimony that a victim had seen a suspect’s apparition — yet lent the prosecutions his pen and his name once they were under way, and never repudiated them as his father more nearly did. The result has made him a lasting emblem of the trials’ cruelty.

What is easy to lose in that emblem is the coherence of the world he inhabited. For Mather the invisible order was not superstition layered over a rational faith but the faith itself: providence governed every event, demons were real adversaries, and a wonder rightly read was a message from God. He kept a voluminous diary recording omens, answered prayers, and visitations he took for angelic, and the same conviction that drove the inoculation campaign — that the visible world ran on hidden causes a vigilant believer could discern — drove the hunt for witches. The line modern readers draw between his science and his demonology is a line he did not draw.

He died in 1728, his influence already waning in a Boston turning toward the Enlightenment. The witch trials had ended in recantation and shame within his own lifetime, and his name was bound to them thereafter. Yet the body of work he left remains one of the fullest records of the Puritan mind at its most learned and most haunted — a mind for which the unseen was never a metaphor.
