The Church worked hard at it night and day during nine centuries and imprisoned, tortured, hanged, and burned whole hordes and armies of witches, and washed the Christian world clean with their foul blood. Then it was discovered that there was no such thing as witches, and never had been. One doesn't know whether to laugh or to cry. Who discovered that there was no such thing as a witch - the priest, the parson? No, these never discover anything.
