|Halley's Comet on the Bayeaux Tapestry|
BCE records suggest Halley's was spotted as early as 467 BCE by the Greeks and the Chinese, but the first report detailed enough to be certain of Halley's pattern was in 240 BCE by a Chinese chronicle.
The 1493 Nuremberg Chronicles used many early sources, one of which mentioned the comet appearing over Europe in 684. The 837 approach—recorded by astronomers in Germany as well as across the Middle East and Asia—was the closest the comet ever came to earth: a mere 3.2 million miles away, and took place on 10 April. The Annals of Ulster—an Irish chronicle extending from 431 to 1540 CE—says of 912 "A dark and rainy year. A comet appeared."
1066 saw the appearance of an invading Norman army in England and the appearance of the comet in the Anglo-Saxon Chronicle, in the Irish Annals of the Four Masters, and later in the Bayeaux Tapestry.
