It is not certain if John Scolvus really existed and whether he reached America aboard these ships. All sources mentioning him were written long afterwards. Some evidence may suggest that Scolvus did exist and sailed to some location in the North Atlantic. Primarily, a 1536 globe of cartographer Gemma Frisius depicts an area within the Arctic Circle, north of a strait dividing Terra Corterealis and Baccalearum Regio from the westward projection of Greenland. Within this area is the inscription, "Quij, the people to whom Joes Scoluss, a Dane, penetrated about the year 1476." According to the Encyclopedia of Newfoundland and Labrador "Based on study of toponymy and cartography, most scholars have concluded that Scolvus visited Greenland and not Labrador." (Friseus’ knowledge of Labrador may have come from Portuguese sources).
