Columbus was in no hurry over his preparations. In the midst of them he found time to collect a whole series of documents relating to his titles and dignities, which he had copied and made into a great book which he called his "Book of Privileges," and the copies of which were duly attested before a notary at Seville on January 5, 1502. He wrote many letters to various friends of his, chiefly in relation to these privileges; not interesting or illuminating letters to us, although very important to busy Christopher when he wrote them. Here is one written to Nicolo Oderigo, a Genoese Ambassador who came to Spain on a brief mission in the spring of 1502, and who, with certain other residents in Spain, is said to have helped Columbus in his preparations for his fourth voyage: "Sir,--The loneliness in which you have left us cannot be described. I gave the book containing my writings to Francisco de Rivarol that he may send it to you with another copy of letters containing instructions. I beg you to be so kind as to write Don Diego in regard to the place of security in which you put them. Duplicates of everything will be completed and sent to you in the same manner and by the same Francisco. Among them you will find a new document. Their Highnesses promised to give all that belongs to me and to place Don Diego in possession of everything, as you will see. I wrote to Senor Juan Luis and to Sefora Catalina. The letter accompanies this one. I am ready to start in the name of the Holy Trinity as soon as the weather is good. I am well provided with everything. If Jeronimo de Santi Esteban is coming, he must await me and not embarrass himself with anything, for they will take away from him all they can and silently leave him. Let him come here and the King and the Queen will receive him until I come. May our Lord have you in His holy keeping. "Done at Seville, March 21, 1502. "At your command. .S. .S.A.S. Xpo FERENS."
