The date of the appearance of “vikingr.” The fact that the old norse word "vic" meant inlet or bay doesn't establish that vikings called themselves vikings prior to the appearance of "wicing." If it did, the literature would just say that they called themselves "vikings" from the word "vic" and point to some primary record of it.
