Domenico Beccafumi, Saint Dominic Burning Heretical Books
It was not until the Inquisition
& the witch-trials got really going,
that the European Manichaean Church & its faithful healers
were truly threatened with extinction.
The point is that there is every reason to believe
that a Manichaean book of the healing arts
would have found an eager home in many parts of Europe,
notwithstanding that only a very few
would actually be able to read it.
Unless some colony of Khaladj Turks
somehow disappeared into the Dark Ages of Europe?
