Some importance, however, attaches to this map in its assisting us to fix approximately the time of the fabrication of the Verrazzano letter. If it were constructed in 1529, as some would infer, with the portions relating to the discovery upon it, then it is the earliest recognition of the CLAIM to this discovery yet produced, irrespective of the letter. But it is by no means certain that it was originally made in that year. Nothing appears on the map itself giving that date in terms; but it is left to be inferred exclusively from the language of the legend, which states that the discovery was made FIVE YEARS AGO, without any indication, either in the legend itself or elsewhere on the map, to what time that period relates; and leaving the discovery, therefore, to be ascertained from extraneous sources. If the discovery be assumed to have been made in 1524, then indeed the map, according to the legend, would have been constructed in 1529. But no person, unacquainted with the letter, can determine from this inscription, or any other part of the map, the date either of the discovery or map; and this precise difficulty Euphrosynus Ulpius apparently encountered in attempting to fix the time of the discovery for his globe, as will hereafter be seen. Why the time of the discovery should have been left in such an ambiguous state, compatibly with fair intentions, it is difficult to understand. The year itself could and should, in the absence of any date on the map, have been stated directly in the legend, without compelling a resort to other authorities. It is not unusual, it is true, for valuable maps and charts of this period to be left without the dates of their construction upon them; but when, as in this case, a date is called for, there seems to be no reason why it should not have been given. This circumstance creates the suspicion that the legend did not belong to the map originally, but was added afterwards, as it now appears on the copy in the Vatican; or if it were upon it then, that it was intended to mislead and conceal the true date of the map. But whatever may be the secret of its origin, this legend furnishes no positive evidence as to the time when the map was made, or pretended to have been made; and we are left to find its date, if possible, by other means.
