The public mind, under such circumstances, must of necessity have been deeply perturbed, and superstition associated the social and political anarchy which prevailed with the "war of elements," and other attendant mysterious physical phenomena. The trusty old chronicler, duly impressed with the solemnity of his theme, informs us that during the year preceding the murder of Ethelred "dire forewarnings came over the land of the Northumbrians and miserably terrified the people; these were excessive whirlwinds and lightnings, and fiery dragons were seen flying in the air. A great famine soon followed these tokens; and a little after that, in the same year, on the 6th before the Ides of January, the ravaging of heathen men lamentably destroyed God's Church at Lindisfarne through rapine and slaughter." The "heathen men" here referred to were Danish rovers. These "Northmen, out of Hæretha-land" (Denmark), had a few years previously (787), in three ships, "first sought the land of the English nation," and, having found it and pronounced it good, they ceased not their invasions until they became masters of the entire kingdom, under Canute the Great. This conquest of the Northmen mainly resulted from the fact that the English monarchs of the Heptarchy were continually at war either with the Britons or amongst themselves. "Domestic treason and fierce civil strife" added additional strength to the foe, for both regal enemy and rebellious subject eagerly sought the aid of the pirates, or selected the occasion of their hostile visits to harass their opponents. Although we have no record of Danish or other Northmen's ravages in Lancashire in the reign of Ethelred or his successor, yet we get a very distinct view of their doings on the eastern coast of Northumbria, and of the internecine strife which rendered the kingdom a relatively easy prey to the brave but brutal and remorseless heathen pirates.
