The Comets of the Thirty Years' War
What happened
Three highly visible, brilliant comets appeared in rapid succession over Europe, observed with terrifying clarity in cities like Prague and London. Coming immediately after the Defenestration of Prague, these celestial bodies were universally interpreted by both Catholics and Protestants as terrifying signs of impending divine wrath and apocalyptic devastation. This shared cultural dread was swiftly realized as Europe descended into the catastrophic Thirty Years' War, one of the most destructive conflicts in human history.
Literary impact
The comets triggered an enormous outpouring of lamentation poetry and political broadsheets across Germany and England. They became permanent literary symbols for the horrors of war and the complete collapse of social order within 17th-century European verse.
