Snorri Sturluson,
Heimskringla — Saga of Olaf Herladson…
“ Hrorek said, "Why should we live longer as mutilated men with disgrace? I, a blind man, may conquer them as well as they conquered me when I was asleep. Come then, let us kill this thick Olaf. He is not afraid for himself at present. I will lay the plan, and would not spare my hands if I could use them, but that I cannot by reason of my blindness; therefore thou must use the weapons against him, and as soon as Olaf is killed I can see well enough that his power must come into the hands of his enemies, and it may well be that I shall be king, and thou shalt be my earl." ”
