Besides the theology espoused by their religious leaders, the people of Plymouth Colony had a strong belief in the supernatural. Richard Greenham was a Puritan theologian whose works were known to the Plymouth residents, and he counseled extensively against turning to magic or wizardry to solve problems. The Pilgrims saw Satan's work in nearly every calamity that befell them; the dark magical arts were very real and present for them. They believed in the presence of malevolent spirits who brought misfortune to people. For example, in 1660, a court inquest into the drowning death of Jeremiah Burroughs determined that a possessed canoe was to blame. Massachusetts Bay Colony experienced an outbreak of witchcraft scares in the 17th century, but there is little evidence that Plymouth was engulfed in anything similar. Witchcraft was listed as a capital crime in the 1636 codification of the laws by the Plymouth General Court, but there were no actual convictions of witches in Plymouth Colony. The court records only show two formal accusations of witchcraft. The first was of Goodwife Holmes in 1661, but it never went to trial. The second was of Mary Ingram in 1677 which resulted in trial and acquittal.
