The map of Agnese stands, therefore, as the earliest chart of an acknowledged date showing the western sea, and that is independently of the Verrazzano discovery, or the Verrazano map. The hitherto unpublished maps produced by Mr. Kohl, also for the purpose of proving the influence of the Verrazzano discovery, fail entirely of that object. The first of them, in point of date, the sketch (No. XV. c) from the portolano of 1536, preserved in the Bodleian library at Oxford, shows a track of navigation from the north of France, across the Atlantic, RUNNING BETWEEN THE BACALAOS AND THE LAND OF THE BRETONS, THROUGH THE GULF OF ST. LAWRENCE, TO THE PACIFIC, AND THENCE TO CATHAY. There is no representation of the western sea, as shown on the Verrazano map, but on the contrary, the whole of the western coast of North America is shown conjecturally in a different form, by dotted lines. So far as this map affords any indication on the subject, it refers to the route of Cartier, and delineates the Atlantic coast according to the Spanish map of Ribero, that is, with a trending of the coast in a more northerly direction than the Verrazano map, and with the peculiar return of that coast westerly, in latitude 40 Degrees N., given on that map. The next chart (No. XV. d) from a map made by Diego Homem in 1540, shows the western sea nearly the same as on the map of Agnese, but conjecturally only; while the representation of the Atlantic coast has the same characteristics as the Bodleian and Agnese maps, showing its derivation from Ribero and not the Verrazano map. The remaining sketch given by Mr. Kohl (No. XV. b) from a map made by G. Ruscelli in 1544, presenting the same features, as do the two others, in regard to the Atlantic coast, puts beyond all question that the map of Ribero is its authority, by adopting from it the name of Montagne Verde which is applied by Ribero to the hills at the mouth of the river San Antonio, in latitude 41 Degrees N., thereby certainly excluding any recognition of the Verrazzano discovery or the Verrazano map.
