A fact which indicates that this map could not have existed as late as 1536, in the form in which it is now presented, if it existed then at all, is that the western sea is delineated upon a map of the world, made in that year, by Baptista Agnese, an Italian cosmographer, without any reference to the Verrazzano discoveries, under circumstances which would have led him to have recognized them if he knew of them, and which would have required him to have done so if this map were his authority. This sea is laid down by Agnese in the same manner as it is shown on the Verrazzano map, approaching the Atlantic, from the north, along a narrow isthmus terminating at latitude 40 Degrees, with the coast turning abruptly to the west; the ocean being thus represented open thence from the isthmus to Cathay. A track of French navigation, not a single voyage, expressed by the words: el viages de France, is designated upon it, leading from the north of France to this isthmus, referring obviously to the voyages of the fishermen of Brittany and Normandy, to the coasts of Nova Scotia and New England. No allusion is made to the voyage of Verrazzano, or to the discoveries attributed to him by the Verrazano map. The Atlantic coast on the contrary, is plainly delineated after the Spanish map of Ribero, as is shown by the form, peculiar to that map, of the coast, at latitude 40 Degrees, returning to the west. It is apparent, therefore, that the two maps of Agnese and Verrazano, both representing the western sea in the same form, must have been derived from a common source, or else one was taken from the other; and that the map of Agnese could not, in either case, have been derived from a map showing the Verrazzano discovery, and must consequently have been anterior to the Verrazano map in its present form. It militates against the authenticity of the Verrazano map and the early date which it would have inferred for itself, that there is not a single known map or chart, either published or unpublished, before the great map of Mercator in 1569, that refers to the Verrazzano discoveries, or recognizes this map in any respect before that of Michael Lok, published by Hakluyt, in 1582; or any before Lok, that applies the name of the sea of Verrazano to the western sea. The unauthenticated and until recently unnoticed globe of Euphrosynus Ulpius, purporting to have been constructed in 1542, of which we will speak presently, is the only evidence yet presented of the existence of the Verrazano map, as it now appears, beyond the map itself. The whole theory of the early influence of the Verrazzano discovery, or of the Verrazano map, upon the cartography of the period to which they relate, and its consequently proving their authenticity, as advanced by some learned writers, is therefore incorrect and is founded in a misconception of fact.
