Well I wasn't sure, and I found it difficult to find texts from the early-modern period, that's why I broadened it out to 1600s and
1700s, but now I realise that's way too broad! Probably mid-1600s if I had to narrow it down.
I was thinking of writing a paper on it, but then I decided that I'd probably be too close to the subject area and couldn't help but be subjective so I've changed the title of the paper but am still going to study this in my own time anyway (hence the post). I've found some interesting spellbooks/magic manuals - however you describe them - from this period so was interested to see if these ideas were in fiction of that time too. Just a curiosity really! I will post on these when I've gone over them a few more times.
Oh I've rambled, but did I answer your question specifically enough Dark Waters
