Often in the Medieval ages, comets were interpreted as signs
and omens. Certain events were recorded after the documentation
of the comet with an intent to link them. However, 677 AD was
one of the many years that Medieval historians began to take notice
and record the appearance of comets without linking them to
specific events. This is specifically written in the Ethelwerds
Chronicle of the Flores Historiarum compiled by Matthew Paris
[1]. It writes: "In the year of grace 677, Donus sat in the Roman
chair one year, five months, and ten days, after which the see remained
vacant ten months and fifteen days. At this time flourished
St. Etheldrida, in the Isle of Ely. In these days also appeared
a comet for three months, and each day it shone in the
morning with a splendour equal to the sun" [2]. This is one of the
first documentations of comets that was not linked to any following
events.
