“And often in my own mind, comparing the land explorations of these our Venetian gentlemen with the sea explorations of the aforesaid Signor Don Christopher, I have asked myself which of the two were really the more marvellous. And if patriotic prejudice delude me not, methinks good reason might be adduced for setting the land journey above the sea voyage. Consider only what a height of courage was needed to undertake and carry through so difficult an enterprise, over a route of such desperate length and hardship, whereon it was sometimes necessary to carry food for the supply of man and beast, not for days only but for months together. Columbus, on the other hand, going by sea, readily carried with him all necessary provision; and after a voyage of some 30 or 40 days was conveyed by the wind whither he desired to go, whilst the Venetians again took a whole year’s time to pass all those great deserts and mighty rivers. Indeed that the difficulty of travelling to Cathay was so much greater than that of reaching the New World, and the route so much longer and more perilous, may be gathered from the fact that, since those gentlemen twice made this journey, no one from Europe has dared to repeat it,[3] whereas in the very year following the discovery of the Western Indies many ships immediately retraced the voyage thither, and up to the present day continue to do so, habitually and in countless numbers. Indeed those regions are now so well known, and so thronged by commerce, that the traffic between Italy, Spain, and England is not greater.” [Sidenote: Recounts a tradition of the travellers’ return to Venice.] 5. Ramusio goes on to explain the light regarding the first part or prologue of Marco Polo’s book that he had derived from a recent piece of luck which had made him partially acquainted with the geography of Abulfeda, and to make a running commentary on the whole of the preliminary narrative until the final return of the travellers to Venice:—
