Very interesting post, Bob! I noticed somewhere on the Internet a few days ago that Bill O'Reilly had recently written this book, "Killing the Witches," and it seemed rather surprising material. Having read quite a bit on the Salem witchcraft over the years, and given that I am not particularly inclined towards reading, listening to, or watching Bill O'Reilly, I let it go at that. But from what you write in your post, perhaps the book would be worthwhile. (I wonder what O'Reilly's interest in it was that he wrote a book about it?) The problem I've encountered with more academic approaches to the subject over the years is that historians and professors always have to come up with a new theory to explain the incident, something new that challenges everything previously thought on the topic, and often seemingly stretching their sources to come up with yet another revolutionizing thesis that in the end is less than satisfying. So perhaps a more journalistic overview should be welcomed.
I had never thought of the parallels you make with DS's treatment of witchcraft, especially in the 1795 storyline, but it makes perfect sense. The Reverend Trask's beliefs and actions do bear some resemblance to the Rev. Cotton Mather, though that had never occurred to me -- religious fanaticism in its full glory. And I think I dismissed any comparison of Angelique with Tituba because of the difference in race, and looked no further.
One of the most difficult things to explain in many of the witchcraft cases isn't the hysterical playacting of the girls (in the case of Salem) but manifestations of the afflicted such as disgorging pins, etc. etc.
Which brings me to the supposedly astonishing and hard to explain "possession" of "Roland Doe" in the Maryland - St. Louis exorcism case. Having read a lot on that case, too, it is almost convincing, until you read the truly investigative and groundbreaking journalism of Mark Opsasnick's "The Haunted Boy" in "Strange" Magzine in 1999 or 2000, which punched the first holes in the case (he was the first to track down who the boy really was, where he lived, and interviewed some of the boy's classmates of the time). But it really took the death of "Roland Doe" (not his real name) two or three years ago and some comments made by his common-law wife after his death published in The New York Post to reveal the truth. A couple of quotes (which anyone can probably copy and google to obtain the article): According to Hunkeler’s companion, the man himself never believed that he was the victim of satanic possession and he shunned religion.
"He said he wasn’t possessed, it was all concocted," said the companion. "He said, 'I was just a bad boy.' "
It's surprising that this prosaic expose has not made a dent in the popular online accounts and books that continue to appear. People want to believe in something extraordinary that defies all logical explanation.
Finally, all this reminds me how I discovered a couple of troubling things in the course of my geneaological research over many, many years. Given my own attraction to stories of the supernatural, witches, vampires, and the like, since childhood, it has been disconcerting to come across documentary evidence of ancestors who were more on the Trask side than that of the witches (though I can counter that with a great-grandfather's water divining ("water witching") and great-grandmother's interpreting signs in nature as supernatural (a black bird's landing on the gable of a house and her comment "someone in that house will die soon," as reported to me by a late aunt of mine). But the other discoveries include a soldier ancestor in the early 1600s duchy of Lorraine (which later became part of France) who testified against a woman accused of witchcraft whom he had discovered doing some strange practice in the woods), and a more recent discovery in a line of clergy ancestors (which I was unaware of previously) extending from Finland into Sweden, and in the church biography from the 1600s of this renowned Swedish clergyman it is mentioned how as ecclesiastic judge (the church was the state) he brought a notorious witch to trial (her recitation of a spell at the trial is in the record) and had her thrown in prison. The outcome of the case isn't given.
