The "Gamaleon" prophecy is an interesting case of remarkable fifteenth-century manuscript transmission (Frances Kneupper's Empire at the End of Time records 16 manuscripts in three versions) and considerable secondary literature, followed by near silence in print. There is a single printed edition of 1538 (VD16 O 508). Otherwise "Gamaleon" only appears in Wolfgang Lazius' 1547 Fragmentum vaticinii and 1554 Catalogus aliquot antiquorum vaticinorum, Matthias Flacius' 1556 Catalogus testium veritatis, and Johann Wolff's massive collection in 1600.
We can extend this slightly with a few mentions of Gamaleon in other sources. Editions of "Alofresant" printed in 1530-40 and expanded with additional texts, mostly borrowed from Lichtenberger's Prognosticatio, cite "Gamaleone" or "Damaleone" as one of their authorities (VD16 A 1936 and ZV 416, A 1934), but without including any of the "Gamaleon" prophecy. Caspar Füger's 1568 Weissagung von der künftigen Zerstörung deutsches Landes durch den Türken in verse includes a note referencing "Gamaleon" in the version attributed to the sermon of a Johann Wünschelberg of Amberg: Lichtenberger had prophesied an advance of the Turks to Cologne, and "Desgleichen hat gesagt ein Prediger zu Ambergk/ Wintschelbürger genant. Was diese beyde sonst geweissaget haben/ soll alles also ergangen sein." For a century with an ongoing interest in prophecies, that's not much.
Outside of antiquarian collections, "Gamaleon" actually looks to be better attested in the seventeenth century. Short excerpts from the prophecy are found in the following editions:
Newe Zeitung auß Bayerlandt/ ... Die ander/ Von dem Gesicht oder Visio Hemalionis, welches zu Heydelberg in der Cantzeley ist gefunden worden, 16221 (VD17 1:070329C): "Es ist in einer Archa oder Kist/ so in hundert Jahren nit geöffnet/ darinnen allerhand Brieff und Documenta gewesen/ under andern auch diese Schrifft gefunden worden. Ein Brieff darinnen ein Kind gemahlt gewesen/ welches ein Cron auff dem Haupt gehabt/ unnd vier Schwerdter in seinen Handen die Oberschrifft ist genant worden Visio Hemalionis, etc..."
This text appears to be reprinted in Klägliche und trawrige Newe Zeitungen... Die ander/ Von dem Gesicht oder Visio Hemalionis, welches zu Heydelberg in der Cantzeley ist gefunden worden, 1621 (VD17 23:246515X), but no full facsimile is available yet.
Warhaffte Propheceyung Dreyer im Bapstumb Hochberühmbter Fürtrefflicher Männer, 1632 (VD17 23:296469W): "Der Erste ist gewesen Johannes Wund. Schellenburgensis Theologus und Praedicator zu Hamburg/ welcher umbs Jar Christi 1400 und also länger als vor 200. Jahren gelebt hat/ dessen Wort in seiner Weissagung also lauten: Imperator veniet a meridiae, qui incipiet malum Ecclesiae...et possessionem auferent ab Ecclesia:" followed by a German translation of the excerpt.
In addition, an anonymous Latin Iudicium De Hodiernis Prognosticis Liberum published in 1623 (VD17 12:121696G) mentions "M. Johannes Vunschelburg, oppidi in Bavaria Ambergae praedicator: anno 1439" among its list of older prophecies.
