ANNOTATIONS BY COLUMBUS.

An important element in the problem was the statements of Marco Polo regarding a large island, which he called Cipango, and which he represented as lying in the ocean off the eastern coast of Asia. This carried the eastern verge of the Asiatic world farther than the ancients had known; and, on the spherical theory, brought land nearer westward from Europe than could earlier have been supposed. It is a question, however, if Columbus had any knowledge of the Latin or Italian manuscripts of Marco Polo,—the only form in which anybody could have studied his narrative before the printing of it at Nuremberg in 1477, in German, a language which Columbus is not likely to have known. Humboldt has pointed out that neither Columbus nor his son Ferdinand mentions Marco Polo; still we know that he had read his book. Columbus further knew, it would seem, what Æneas Sylvius had written on Asia. Toscanelli had also imparted to him what he knew. A second German edition of Marco Polo appeared at Augsburg in 1481. In 1485, with the Itinerarius of Mandeville,[91] published at Zwolle, the account—“De regionibus orientalibus”—of Marco Polo first appeared in Latin, translated from the original French, in which it had been dictated. It was probably in this form that Columbus first saw it.[92] There was a separate Latin edition in 1490.[93]
The most definite confirmation and encouragement which Columbus received in his views would seem to have come from Toscanelli, in 1474. This eminent Italian astronomer, who was now about seventy-eight years old, and was to die, in 1482, before Columbus and Da Gama had consummated their discoveries, had reached a conclusion in his own mind that only about fifty-two degrees of longitude separated Europe westerly from Asia, making the earth much smaller even than Columbus’ inadequate views had fashioned it; for Columbus had satisfied himself that one hundred and twenty degrees of the entire three hundred and sixty was only as yet unknown.[94] With such views of the inferiority of the earth, Toscanelli had addressed a letter to Martinez, a prebendary of Lisbon, accompanied by a map professedly based on information derived from the book of Marco Polo.[95] When Toscanelli received a letter of inquiry from Columbus, he replied by sending a copy of this letter and the map. As the testimony to a western passage from a man of Toscanelli’s eminence, it was of marked importance in the conversion of others to similar views.[96]
It has always been a question how far the practical evidence of chance phenomena, and the absolute knowledge, derived from other explorers, bearing upon the views advocated by Columbus, may have instigated or confirmed him in his belief. There is just enough plausibility in some of the stories which are cited to make them fall easily into the pleas of detraction to which Columbus has been subjected.
