Jacob Böhme. Theosophia revelata. s.l., s.n., 1730

When F.C. Oetinger, a follower of Jacob Böhme, asked the Frankfurt Kabbalist Koppel Hecht (d. 1729) how he might best gain an understanding of the Kabbalah, Hecht referred him to Jacob Böhme (1575-1624), a Christian author whose metaphors, Hecht told him, nevertheless bore close resemblance to those of the Kabbalah. Böhme's doctrine of the origins of evil, for instance, whereby he defined evil as a dark and negative principle of the wrath of God, bears all the characteristics of Kabbalistic thought. The affinity between his ideas and those of the theosophical Kabbalah were evident to all of Böhme's followers, from Abraham von Franckenberg (d. 1652) to Franz von Baader (d. 1841).
