Eclipses in Ancient Rome: Omens, Politics, and the Sun's Divine Role

A historical analysis by Javier Andreu Pintado, Professor of Ancient History at the University of Navarra, explores the multifaceted significance of eclipses in ancient Rome. Published originally at The Conversation, the piece examines how Romans combined scientific understanding with religious interpretation. On August 12, Europe, particularly the Iberian peninsula, will witness a historic solar eclipse, prompting reflection on ancient views. In Rome, eclipses were seen as prodigia—omens signaling a disruption between gods and men—requiring state religious responses. Despite inherited Greek astronomical knowledge, Romans believed eclipses conveyed divine messages. Notable examples include Emperor Claudius publicly announcing an eclipse in AD 45 to prevent panic, and the Senate decreeing rituals after an eclipse in 340 BC. Eclipses were also linked to political crises, such as the Battle of Pydna in 168 BC and the omens preceding the fall of the Republic. Cicero interpreted the eclipse of May 18, 63 BC as a bad omen for his consulship. The common people, lacking access to scholarly works, experienced eclipses with fear, resorting to noise-making to help the Sun regain its light. The article highlights the coexistence of empirical and superstitious worldviews, offering insight into Roman cosmology and its political implications.
