Mayde

Mayda is a phantom island in the North Atlantic Ocean that appeared on maps from the 14th century until the early 20th century. Typically depicted as crescent-shaped and positioned west of Brittany or southwest of Ireland, approximately at 46° to 48° N latitude, Mayda was among the most persistent of the Atlantic phantom islands. Alexander von Humboldt observed around 1836 that of the numerous legendary Atlantic islands, only Mayda and Brazil Rock still appeared on contemporary charts.
