Porfinnur Karlsefni's group also encounters a uniped and they hear rumors of a nearby country of white men.
The unipeds were also known in Iceland; a picture of a uniped is found in a manuscript of the Old Icelandic Physiologus from around 1200.
The nation of the unipeds appears in several ancient sources, most famously in the Naturalis historia of Pliny the Older (23-79).
This information provided the background for much of the speculation surrounding unipeds in medieval learned works.
Beyond the land of the unipeds, according to Eiriks saga rauoa, there lay another country.
On this matter, Eiriks saga rauoa offers further clues, mainly due to the proximity of Winland to the land of the unipeds and the land of the white men.
