Source chain origin
The item known as Himmelserscheinung über Nürnberg vom 14. April 1561 is cataloged in Zentralbibliothek Zürich as a 1561 single-sheet woodcut by Hans Glaser, preserved in PAS II 1/12 with persistent bibliographic identifiers and stable archival metadata.12 It also appears as an identifiable digital object with direct download and manifest endpoints, confirming institutional provenance from acquisition to reuse workflow.34
Who reported/observed
The printed text states that in the morning of 14 April 1561, between four and five o’clock, many men and women in Nuremberg and the surrounding area saw a “dreadful spectacle.”15 The report therefore presents as a communal observational claim and a moralizing publication rather than a named eyewitness deposition.56
Interpretation evolution
Contemporary catalog summaries describe the print as a warning-shaped account and link it to a prodigies tradition in which divine messaging framed celestial reports.16 Modern scientific discussion has moved toward atmospheric explanations, with current media interpretation identifying the motif as a halo display rather than a literal aerial battle while noting that broadsheet imagery could include stylistic exaggeration.7 A second institutional catalog chain in the Swiss Discovery environment preserves the same object under Zürich control, anchoring both historical theology-driven circulation and later archival reinterpretation in the same collection lineage.82
