Page "Hróa þáttr heimska" Paragraph 9

Concerning Þorir's accusation of the stolen eye, Hrói suggested that the stolen eye be removed from his head, and the last eye from Þorir's head.

Then the eyes would be weighed and if they weighed equally it would be proven that they came from the same head, and that Hrói had stolen Þorir's eye.

If Þorir would not agree to this, he would be proven a liar in this case and in others.
