Nathaniel Holmes (or Homes) (1599–1678) was an English puritan, covenanter and prolific Calvinistic writer. He is described as a Puritan writer of great ability, and a scholar. C. Matthew McMahon is a theologian and founder of A Puritan's Mind. The following treatise covers demonology, a study of the devices and black arts of Satan. The study launches with 1 Timothy 4:1, “...giving heed to seducing spirits, and doctrines of devils.” The treatise investigates the occult and the black arts in two ways: 1.Generally, considering them in their causes and means; and, 2. Specially, looking at particular arts pertaining to the operation of strange things like charms, luck, witchcraft, divination by familiar spirits, casting lots, necromancy and astrology (the section on astrology is astoundingly exhaustive and helpful).
