Halley's Comet makes a close appearance, before the Battle of Hastings in 1066, around April 24, 1066. The event is believed to have been captured on the Bayeux Tapestry, an embroidered cloth depicting the events leading to the Norman conquest of England in 1066. The comet was visible for over a month and was interpreted by contemporaries as a bad omen for King Harold II and a good omen for William of Normandy.
The Bayeux Tapestry was commissioned around 1077, likely by Bishop Odo, it details the invasion, crossing of the sea, and key moments of the conquest. The closest known Halley's appearance occurred in 837 BCE. The comet was first recorded in China on April 2, 1066, and later seen in Europe and England around April 24, 1066.
