An Anabaptist man stabbing his mother. Etching.

Anabaptists: part of the radical wing of the Reformation, consisting of preachers and congregations in the tradition of medieval mysticism and millenarianism who believed that Luther and Zwingli had stopped halfway towards reform by compromising with existing governments and churches. The fanatical violence and sexual heterodoxy of the Siege of Münster in 1536 gave Anabaptism a bad name, and as this print shows, does not put matricide past them.
