The Great Comet of 1577 and Spain's Imperial Astrology

In 1577, a brilliant comet blazed across European skies, sparking fear, wonder, and a fierce debate among Spanish scholars about whether celestial omens could predict the fate of empires. This episode follows the comet's trajectory through the Spanish court of Philip II, where royal astrologers and astronomers clashed over its meaning. We meet Jerónimo Muñoz, the Valencian mathematician who published one of the first empirical studies of the comet, arguing it was a celestial body beyond the moon—a radical idea that challenged Aristotle. Meanwhile, the Inquisition kept a wary eye on such discussions, as divination and natural philosophy tangled in a deeply Catholic monarchy. We also explore how the comet was interpreted as a sign of Spain's growing power or impending decline, and how this moment fits into the broader story of Spain's Golden Age and its scientific contributions, often overshadowed by the Black Legend. This episode uses the comet as a lens onto Spain's intellectual history, showing a kingdom grappling with new cosmologies while policing orthodoxy. #GreatComet1577 #JerónimoMuñoz #PhilipII #SpanishAstrology #Comet #HabsburgSpain #Inquisition #GoldenAgeSpain #HistoryOfScience #Astronomy #Renaissance #Omens #ImperialSpain #Valencia #Salamanca #Aristotle #Cosmology #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo
