[1493.] Just before reaching the Azores, Columbus wrote on shipboard two letters describing his voyage, one under date of the 15th of February, and the other of the 14th of March. The manuscript of one, with copies printed in Spain probably during this same year, are yet preserved. Of the other, both the original manuscript and Spanish copies, if any were printed, are lost; but of a Latin translation, six editions are extant, supposed to have been printed in 1493, in France and in Italy, under the title _Epistola Christofori Colom_, or _De Insulis Inventis_, etc. A poetical paraphrase of the same letter appeared the same year as _Dati_, _Questa e la Hystoria_, etc., Florence, 1493, and four other works of this year contain slight allusions to Columbus. Seven or eight editions of Columbus' letters appeared in different forms during the next forty years. Both letters may be found with Spanish translations in the first volume of Navarrete's collection. For the bibliographical notices of this sketch I have depended chiefly on Harrisse, _Bib. Am. Vet._, as the latest and most complete essay on early American books, notwithstanding the few blunders that have subjected it to so much ridicule. I shall not consider it necessary to repeat the reference with each notice, as Harrisse's work is arranged chronologically.
As soon as Columbus had explained to Ferdinand and Isabella the nature of his important discovery, the Spanish sovereigns applied to the Pope for the same grants and privileges respecting lands discovered, and to be discovered, in the west, that had before been granted the Portuguese in the south and east. His Holiness, accepting the Spanish statements that the concessions demanded did not in any way conflict with previous grants to the Portuguese, by bull of May 2, 1493, ceded to Spain all lands which might be discovered by her west of a line drawn from pole to pole, one hundred leagues west of the Azores; the Portuguese to have all new lands east of the same line. It is obvious that his Holiness fixed this line arbitrarily, without a thought of the position or importance of the corresponding meridian at the antipodes. This opposite meridian, according to the idea of longitude entertained at the time, would fall in the vicinity of India proper; and the Portuguese, besides their natural jealousy of this new success of Spain, feared that the western hemisphere thus given to her rival might include portions of their Indian grants. Hence arose much trouble in the few following years between the two courts. See _infra_.
