witch hunts was between 1450-1750 horse hair and silk were used as fishing line in 1596 (this info was mentioned in a book that was made at that time so horse hair fishing and other tiny string rope were publicly available before then), I looked this up thinking lines weren't invented in those times, then I looked up playing cards and the earliest record of those in Europe was " a ban on card games in the city of Berne in 1367", so I was surprised that this could be a real event during the witch trial years
"The earliest known book to explain magic secrets, The Discoverie of Witchcraft, was published in 1584. It was created by Reginald Scot to stop people from being killed for witchcraft. During the 17th century, many books were published that described magic tricks." just found this 2min after posting top part
