The Witchcraft Delusion in New England (Vol. 1-3)

Cotton Mather (1663-1728) was a New England Puritan minister, prolific author, and pamphleteer. He is remembered for his involvement in the Salem witch trials. In an effort to promote the ongoing trials, Mather wrote Wonders of the Invisible World. After exchanging letters with Cotton Mather and many other area ministers, Robert Calef (1648-1719) wrote More Wonders of the Invisible World, a book composed throughout the mid-1690s denouncing the recent Salem witch trials of 1692–1693 and particularly examining the influential role played by Cotton Mather.
