Matthew Hopkins was a British Joe McCarthy type who in the seventeenth century claimed to have the ‘Devil’s List’ of all the witches in England. Just as Tailgunner Joe’s list of 160,000 Communists, or homosexuals, or whatever it was, shaped the domestic policy of his nation, so Matthew Hopkins made a thriving living chasing down witches and to a lesser extent warlocks in East Anglia 300 years ago.
