While researching the question What are the earliest known origins of Sasquatches in Native American culture in the Americas? I found several sites claiming that Leif Ericson recorded an encounter with sasquatch in 968 AD. For example, the Sasquatch Chronicles Blog:
The oldest account of Bigfoot was recorded in 986 AD by Leif Ericson and his men. During their first landing in the New World, the Norsemen wrote about manlike beasts that were “horribly ugly, hairy, swarthy and with great black eyes.”
Among his accounts, Leif told of seeing huge hairy men who towered over him and his men. The “huge hairy men”, according to Leif, lived in the Woods and had a rank odour and a deafening shriek. It should be noted that Leif Ericson and his men describe huge manlike beasts that were loud and foul-smelling and clearly distinct from native peoples. Apparently, Leif had several sightings of the “huge hairy men” before departing the island.
They called the creature “Skellring”. People believe that the creature “Skellring” is what we know today as Bigfoot. This is the earliest recorded encounter with Bigfoot, or Sasquatch.
What is the source of this story? Is an encounter with a creature that resembles sasquatch mentioned in any of the sagas that chronicle Leif Ericson's travels?
