Increase Mather (1639–1723) was an influential Puritan minister and leader of Massachusetts Bay Colony. Mather was a traditionalist who clashed with more liberal members of the church. With his son, Cotton, Mather is also remembered for his part in the Salem witch trials. The Mathers served as advisors to the trial judges, pressuring them not to rely on “spectral evidence,” and in 1693 Increase published his Case of Conscience Concerning Evil Spirits Personating Men, justifying the Mathers’ role in the trials.
Cotton Mather (1663–1728) was the Boston-born son of Increase Mather, a prominent Puritan minister. Cotton was an influential church leader in his own right, but he is most widely remembered for his role in the Salem witch trials. Although he cautioned the judges against relying on “spectral” evidence he did view New England as a battleground in the war against Satan and defended the trials and his participation in them in his 1693 book Wonders of the Invisible World.
