It has been noted that the themes taken from "Daemonologie" and King James' involvement in the North Berwick witch trials may have directly contributed to Shakespeare's work "Macbeth". Evidence of this exists in the three witches' use of ritual magic and direct quotes that directly relate to the testimony given from the witch trials described in the "Newes of Scotland" pamphlet. "Macbeth" had come into public enjoyment a few years after the publication of "Daemonologie" and retains many of the same Scottish themes and settings.
