If you want to see the context of Johannes Rosenbach/Johannes de Indagine citing Johannes Lichtenberger - the only vaguely credible claim to be an eyewitness account of Lichtenberger - the quick approach is to click here.
The long approach is to start with the footnotes in Dieter Kurze's work on Lichtenberger (11 n. 36 and 40 n. 289) and look up the cited edition (1522) of Rosenbach's Introductiones apotelesmaticae in chiromantiam. That's easy enough, and leads to VD16 R 3108. It's been digitized, so you can see the facsimile from the BSB here (if the URN resolver is working correctly - today it's not - and it doesn't require a cumbersome search to find the right link). We're looking for leaves 15v and 30v. If you turn to them, you find...pictures of hands, but no mention of Lichtenberger. You can try counting the leaves from the beginning, and you might notice that the first few leaves may be misarranged in the Munich copy. Does it help to read through them carefully and try to restore their correct order? No, it does not. How does Kurze know that Rosenbach/Indagine cites Lichtenberger? Kurze cites the biography in ADB; does that offer any clues? No, not really. But the biography of Lichtenberger there mentions Rosenbach/Indagine's mention of Lichtenberger in his foreword to the Introductiones apotelesmaticae. Will reading the foreword turn up what you are looking for? No? Maybe in the 1523 German translation, or the 1534 or 1541 Latin editions? No, no, and no.
But if you spend enough time leafing through the Introductiones apotelesmaticae, you may eventually notice that the folio numbering restarts just as Rosenbach begins to discuss astrology. If you look at leaves 15v and 30v after that, you will find the discussion of Lichtenberger just as Kurze's footnotes indicated.
I recommend the quick approach.
