We know that Gaspar Cortereal[411] had already before 1500 made some explorations, during which he had discovered a mainland and some islands, but at what precise date it is impossible to determine;[412] nor can we decide upon the course he had taken, but it seems likely it was a westerly one. We know also that in this same year (1500) he made his historic voyage to the Newfoundland region,[413] coasting the neighboring shores, probably, in September and October. Then followed a second expedition from January to October of the next year (1501),—the one of which we have the account in the _Paesi novamente retrovati_, as furnished by Pasqualigo.[414] There was at this time in Lisbon one Alberto Cantino, a correspondent—with precisely what quality we know not—of Hercule d’Este, Duke of Ferrara; and to this noble personage Cantino, on the 19th of October, addressed a letter embodying what he had seen and learned of the newly returned companions of Gaspar Cortereal.[415] The Report of Cantino instigated the Duke to ask his correspondent to procure for him a map of these explorations. Cantino procured one to be made; and inscribing it, “Carta da navigar per le Isole novam^{te} tr.... in le parte de l’India: dono Alberto Cantino Al S. Duca Hercole,” he took it to Italy, and delivered it by another hand to the Duke at Ferrara. Here in the family archives it was preserved till 1592, when the reigning Duke retired to Modena, his library following him. In 1868, in accordance with an agreement between the Italian Government and the Archduke Francis of Austria, the cartographical monuments of the ducal collection were transferred to the Biblioteca Estense, where this precious map now is. The map was accompanied when it left Cantino’s hands by a note addressed to the Duke and dated at Rome, Nov. 19, 1502,[416] which fortunately for us fixes very nearly the period of the construction of the map. A much reduced sketch is annexed. [Illustration: THE CANTINO MAP. This is sketched from Harrisse’s fac-simile, which is of the size of the original map. The dotted line is the Line of Demarcation,—“Este he omarco dantre castella y Portuguall,”—which has been calculated by Harrisse to be at 62° 30´ west of Paris.]
