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early date which it would have inferred for itself, that there is not a single known map or chart, either published or unpublished, before the great map of Mercator in 1569, that refers to the Verrazzano discoveries, or recognizes this map in any respect before that of Michael Lok,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.

This mistake relates to a map which is found in several editions of the geography of Ptolemy printed at Basle, supposed to represent the western sea shortly after the Verrazzano discovery, and consequently as derived from that source.  Mr. Kohl, [Footnote:  We are indebted entirely to Mr. Kohl for our knowledge of the map of Agnese, which he produces, on a reduced scale, in the Discovery of Maine, (chart XIV), with an account of the map and its author (p. 292).] in a chapter specially devoted to the consideration of charts from Verrazzano, reproduces one (No.  XV, a) which he describes as a sketch of North America, from a map of the new world, in an edition of Ptolemy printed in Basle, 1530.  And he adds:  “the map was drawn and engraved A few years after Verrazano’s expedition.  The plate upon which it was engraved, must have been in use for a long time; for the same map appears both, in earlier and much later editions of Ptolemy.  The same also reappears in the cosmography of Sebastian Munster, published in Basle.”  Mr. K. finally observes in regard to it:  “this map has this particular interest for us, that it is probably the first on which the sea of Verrazano was depicted in the form given to it by Lok, in 1582.  I have found no map prior to 1530, on which this delineation appears.” [Footnote:  Discovery of Maine, pp. 296-7.] There is a little confusion of dates in this statement.  Mr. K. states, however, that he had not seen the map of Hieronimo de Verrazano, and evidently derives his information, in regard to the sea of Verrazano, from the map of Lok, who alone gives the western sea the name of Mare de Verrazana, no doubt because he found the sea laid down on the map presented by Verrazzano to Henry VIII, to which reference will presently be made.  Had Mr. K. seen the Verrazano map with the absurd legend upon it, in effect declaring the western sea to have been observed by Verrazzano, he
