The most famous of comets, associated with many important events in history. Records of Halley's Comet appear at least as far back as 240 B.C., and they are found in the Bayeux Tapestry (the apparition of the comet in 1066) and in the Nuremberg Chronicle (the apparition of 1456 and probably those of 684 and 1301).
