This myth tells the story of the appearance of Halley's Comet in 1066, shortly before the Norman conquest of England. The comet was widely seen as a bad omen, and many people believed it foretold the defeat of King Harold Godwinson at the Battle of Hastings.

This myth is particularly interesting because it is one of the few documented instances of a comet being linked to a specific historical event. While there is no evidence that the comet actually influenced the outcome of the battle, its appearance certainly contributed to the widespread fear and superstition surrounding the event.
