The Egil's Saga on Atli the Short
Chapter 1 - Of Kveldulf and his sons. > Chapter 68 - Of Egil's journeyings.
attribution: Atli called Egil unjust and claimed King Eric had rightfully adjudged the property to Bergonund
"Long have we heard, Egil, that you are a most unjust man, but now I shall come to prove it, if you mean to claim at my hands this property, which king Eric adjudged to Bergonund my brother."
attestation: Atli offered twelve-man oaths that he held no money belonging to Egil; Egil challenged him to single combat instead
"Atli offered against it as a lawful defence the oath of twelve men that he, Atli, had in keeping no money that belonged to Egil."
attribution: Atli accepted Egil's combat challenge, saying he had enough loss to avenge from his two slain brothers
"you propose what I ought to have proposed, seeing that I have enough loss to avenge on you. You have done to death my two brothers"
