Less known? His part in promulgating deepening belief in the reality of Witchcraft in Germany, where the Empire became the greatest site in Europe (Scotland a close second) in witchcraft executions in the century or so after his death.
That Aeon story notes Luther's belief in the "drache," derived from the Greek and Latin "draco," but NOT the dragon of Revelation. Rather, in German and German-influenced lands to the east and northeast, it was a sort of household spirit. A "familiar," to use a witchcraft term, which Aeon surprisingly was not.
This, of course, was a Luther who believed in an active devil, once infamously throwing an inkwell at Satan. (That's actually a legend, but that's not the point; what is, is that it's a good illustrative point.)
Aeon's piece looks at the economic incentive to make accusations of witchcraft. (And is not alone. More below.)
But, it ignores some others.
The century after Luther of course culminated with the Thirty Years War.
Witchcraft charges were usually at women, yes. But, in some cases, the women might have powerful husbands, sons or fathers. It was also a useful political weapon. As Aeon notes, an epicenter of witchcraft charges was in Bavaria. Note the map at right. Few people, though, know the Reformation, esp. its Lutheran branch, had a strong foothold there for a few decades, until determined Counter-Reformation activity spilled over from Hapsburg Austrian lands.
The economic dislocations of the war then intensified all aspects of Counter-Reformation, including witchcraft charges.
That third link, the "not alone," notes in Quartz what Aeon does not, that the economic nature of the charges was an angle that was leveraged in the name of religious warfare. It adds one other element, that an increasingly unified designation of what constituted actions of witchcraft arose in Switzerland before it became independent of the Empire. It adds the second element that what we know as Germany led Europe in religious tussles from the time the Albigensians were snuffed out in France.
