The 16th-century Italian explorer Giovanni da Verrazzano applied the name "Arcadia" to the entire North American Atlantic coast north of Virginia. In time, this mutated to Acadia. The Dictionary of Canadian Biography says: "Arcadia, the name Verrazzano gave to Maryland or Virginia 'on account of the beauty of the trees', made its first cartographical appearance in the 1548 Gastaldo map and is the only name on that map to survive in Canadian usage. . . . In the 17th century Champlain fixed its present orthography, with the 'r' omitted, and Ganong has shown its gradual progress northwards, in a succession of maps, to its resting place in the Atlantic Provinces".
