”They had also conquered, or planned to conquer, all the country’s best cities and caused many hardships for the country’s original citizens, for they were – according to their country’s customs – in the habit of combing their hair every day, to bathe every Saturday, to change their clothes frequently and to draw attention to themselves by means of many such frivolous whims. In this way, they sieged the married women’s virtue and persuaded the daughters of even noble men to become their mistresses,” wrote Wallingford.
Not knowing jack shit about Vikings yet (gotta start my research paper soon, though), or knowing shit about the author of this source, other than that he was English (probably) and writing after the fact, I still think that the source is biased. Wallingford's painting a very deliberate picture of vikings as "frivolous" whimsical bundle of stickss that fucked the English's bitches.
Tastes like bias.
