837 – Halley’s Comet races past earth
This event is not recorded in The Anglo-Saxon Chronicle. The Chinese astronomers record this year’s occurrence “branched into two tails”. Apparently, this is one of the closest
fly-bys paths the comet has ever taken past earth (see W.S. Tsu in Popular Astronomy, pp. 196-197 and Ian Ridpath’s blog).
This event is recorded in the story about the life of Louis the Pious. An anonymous scribe called ‘The Astronomer’ describes how Louis at the sight of the comet, devotes himself to prayers, alms, and a little hunting (see Thomas Noble, Charlemagne and Louis the Pious, pp. 292). But was it really Halley’s comet? There is an alternative view, that Louis and The Astronomer observed a different force of nature than the comet (see Scott Ashley in Early Medieval Europe, Vol. 21.1 (2013), pp. 27-49).
