“For example, in one story a Jew convinces a Christian executioner to sell him the heart of a recently executed man for use in a black magic ritual. The executioner’s wife, discovering this deal, convinces her husband to substitute a pig’s heart for the criminal’s. A few days later a huge crowd of pigs appears in the field, and the animals tear each other apart: had a Christian heart been used, the victims would have been Christians instead. When the king of France learns of this, he orders all the Jews in the region killed.8”
