This exquisite 1856 map by J.G. Kohl details phases of explorations of the east as colorful lines and dashes. Explorations of cities are marked by arrows with details of who explored and when beneath. The map also has Sebastian Cabot discovered the Continent of North America” printed across it. His other notes include:”..I have only to add still two observations, one in respect to the earliest discoveries made on this coast by Sebastian Cabot, and the other in respect to the general the great general surveys and explorations of the coast made in the latter of the 18th Century.”The reports, which we have of the voyage of Sebastian Cabot, are extremely vague and insufficient; we do not know which part of the coast he saw near enough, which part he observed only at a distance, which bays or parts he entered, and if he entered any at all; we are likewise not sure about the extent of his discovery towards the South. “It was therefore quite impossible to draw upon the map of Cabot’s voyage with a distinctly colored line. Still such a historical map of the discovery of the East Coast would be very defective if Cabot’s name would not figure upon it at all. Cabot ascertained the great fact, that there was a great continent of North America. Three years after him such a continent was already drawn up on the maps of his authority. He laid the foundation of this whole branch of discoveries, and even on his discoveries the political rights of England to this Continent were founded.””
