Since there are several curious persons (very illustrious and very reverend lord) who not only are pleased to listen to and learn the great and wonderful things which God has permitted me to see and suffer in the long and perilous navigation, which I have performed (and which is written hereafter), but also they desire to learn the methods and fashions of the road which I have taken in order to go thither, [and who do] not grant firm belief to the end unless they are first well advised and assured of the commencement. Therefore, my lord, it will please you to hear that finding myself in Spain in the year of the Nativity of our Lord, one thousand five hundred and nineteen, at the court of the most serene king of the Romans, with the reverend lord, Mons. Francis Cheregato, then apostolic proto-notary, and ambassador of the Pope Leon the Tenth, who, through his virtue, afterwards arrived at the bishoprick of Aprutino and the principality of Theramo, and knowing both by the reading of many books and by the report of many lettered and well-informed persons who conversed with the said proto-notary, the very great and awful things of the ocean, I deliberated, with the favour of the Emperor and the above-named lord, to experiment and go and see with my eyes a part of those things. By which means I could satisfy the desire of the said lords, and mine own also. So that it might be said that I had performed the said voyage, and seen well with my eyes the things hereafter written.
