The first published map which refers to the Verrazzano discoveries, that of Mercator in 1569, makes no reference to the Verrazano map, and does not recognize it in any manner. Mercator was the first to give the name of Claudia to the island of Louise, evidently mistaking the name of the wife of Francis for that of his mother, after whom the island was called, according to the letter, without stating her name. Mercator gives a legend in which he mentions that Verrazzano arrived on the coast on the 17th of March 1524, which is the day according to the version of Ramusio, following our mode of computation, as before explained. It is evident, therefore, that Mercator had the Ramusio version before him, and not the Verrazano map, as his authority on the subject. His delineation of the Atlantic coast, moreover, is according to the plan of Ribero, and he gives no indication of the western sea of the Verrazano map, but mentions in a legend the fresh water inland sea spoken of by Cartier, of the extent of which the Indians were ignorant. The existence of the Verrazano map, much less its date, is obviously not proven by any of the maps or charts to which reference has here been made, and which are supposed to reflect some of its features, or indicate the verity of the Verrazzano discovery. There is, however, some evidence of a positive character, both historical and cartographical, which points to the existence of this map in two different forms, one originally not representing the Verrazzano discovery, and the other subsequently, as now presented.
