When the 'Vinland Map' was announced to the world in 1965, it turned the known history of transatlantic exploration on its head.

Was the depiction of a landmass southwest of Greenland, clearly labelled "Vinlanda Insula", proof of Viking expansion into the New World centuries before Columbus?

Was it really a mythological land though? In 1948, a 45 km-wide point of land at coordinates of 46°23′N 37°20′W was found submerged only 36.5 m below the ocean surface. Significantly, this location due west of Brittany tallies with the earliest map drawings.

Despite its popularity with cartographers for over five centuries, no accounts exist of anyone having visited its shores.

Some have speculated Mayda could have been a very early depiction of Corvo in the Azores, or even the crescent-shaped lands of Bermuda, Cape Cod or Cape Breton in the Americas.
