Halley's Comet's 1066 appearance was seen as a terrifying omen in medieval Europe

Summary

Two articles examine how the appearance of Halley's Comet in 1066 frightened people in the medieval world. The Conversation says the sudden appearance of such a bright comet must have made a deep impression on those who witnessed it. Phys.org describes a sequence on the Bayeux Tapestry showing King Harold beneath the comet, alongside a crowd gazing at the sky, with the caption Isti mirant stella ("those people marvel at the star"). Ghostlike invasion boats appear in the border below, which Phys.org presents as a Norman framing of Harold as a doomed usurper whose betrayal invited destruction.
