374     Comet passed 13.5 million kilometres from Earth.
451     Appeared before the defeat of Attila the Hun at the Battle of Chalons.
530     Noted in China and Europe, but not spectacular.
607     Comet passed 13.5 million kilometres from Earth.
684     First known Japanese records of the comet. Seen in Europe and depicted 800 years later in the Nuremberg Chronicle.
760     Seen in China, at the same time as another comet.
837     Closest-ever approach to the Earth (5 million km). Tail stretched halfway across the sky. Appeared as bright as Venus.
912     Seen briefly in China and Japan.
989     Seen in China, Japan, and (possibly) Korea.
1066   Appeared before the Battle of Hastings. Shown on the Bayeux Tapestry. The comet passed 16.5 million km from the Earth and was described in Europe as looking like a dragon, with multiple tails. Seen for over two months in China.
1145   Depicted on the Eadwine Psalter, with the remark that such ‘hairy stars’ appeared rarely, ‘and then as a portent’.

1301   Seen by Giotto di Bondone and included in his painting The Adoration of the Magi. Chinese astronomers compared its brilliance to that of the first-magnitude star Procyon.
1378   Passed within 10 degrees of the north celestial pole, more northerly than at any time during the past 2000 years. This is the last appearance of the comet for which Oriental records are better than Western ones.
1456   Observed in Italy by Paolo Toscanelli, who said its head was ‘as large as the eye of an ox’, with a tail ‘fan-shaped like that of a peacock’. Arabs said the tail resembled a Turkish scimitar. Turkish forces attacked Belgrade.
