Much later—rather recently, in fact—I became aware that Lothar maintains some peculiar notions as to what "really" happened. Lothar believes that Egon knew Alchemy—that he was, in fact, an adept of such power that he could heal the gravest illnesses, and even raise the dead. Yet he would not, or could not, save the lives of Lothar’s two brothers, whom he loved almost as if they were his own sons. Egon had departed from Leipzig with a broken heart, with no intention of ever coming back. His death in the Harz might have been suicide. Or—again this is all according to the eccentric notions of Lothar—it might have been faked, to hide his own unnatural longevity.
