Excerpt from the Saga of Erik the Red:
"One morning Karlsefni's people beheld as it were a glittering speak above the open space in front of them, and they shouted at it. It stirred itself, and it was a being of the race of men that have only one foot, and he came down quickly to where they lay. Thorvald, son of Eirik the Red, sat at the tiller, and the One-footer shot him with an arrow in the lower abdomen. He drew out the arrow. Then said Thorvald, "Good land have we reached, and fat is it about the paunch." Then the One-footer leapt away again northwards. They chased after him, and saw him occasionally, but it seemed as if he would escape them. He disappeared at a certain creek."
As historians we discuss the journeys of the Norse as, for the most part, factual in nature (as opposed to, say, Odysseus). What then should we do with the Monopods???
