I was just reading up about Halley's Comet in Wikipedia ( http://en.wikipedia.org/wiki/Halley's_Comet[/PLAIN] [Broken] ), and I came across the following two items: "The possibility has been raised that 1st-century Jewish astronomers had already recognized Halley's Comet as periodic. This theory notes a passage in the Talmud which refers to "a star which appears once in seventy years that makes the captains of the ships err."" and "This appearance of the comet is also noted in the Anglo-Saxon Chronicle. Eilmer of Malmesbury may have seen Halley previously in 989, as he wrote of it in 1066: "You've come, have you? ... You've come, you source of tears to many mothers, you evil. I hate you! It is long since I saw you; but as I see you now you are much more terrible, for I see you brandishing the downfall of my country. I hate you!""
