Numerous copies of Florianus' map are known. It usually appears in the Lafreri collection, and Fiorini notes that copies may be found in the Archivo di State of Turin, in the Marciana of Venice, in the Biblioteca Vittorio Emanuele of Rome, in the Biblioteca Comunale of Treviso, in the private library of Professor Marinelli of Florence, in the British Museum, in the private library of Nordenskiöld. To the above may be added the New York Public Library, the Library of Congress, and the Harvard Library, which likewise possess copies.
Among the numerous references appearing here and there in the literature of Italy, assuring us of the interest in that country in globe construction, reference may be made to the record left by Alessandro Piccolomini, a native of Siena, and author of a work on the extent of the land and water,[299] who, in the preparation of his work, made extensive study of the records to be found in plane maps and globes. In his work published in Venice in the year 1558, though his dedication to M. Jacomo Cocco, Archbishop of Corfu, reads August 28, 1557, "Della mia casa di S. Giorgio, di Siena, il di XXVIII di Agosto MDLVII," he tells of several globes which it had been his privilege to examine. "I have zealously examined geographical maps, both plain and spherical, and especially those which are reputed to be most faithful, for example, among others, a solid terrestrial sphere shown me by Cardinal Viseo.[300] Another I saw at the home of the Cardinal of Carpi,[301] exhibiting mountain elevations in a new and excellent manner, and still another much larger kept at present at the home of Cardinal of Urbino.[302] There is also a globe having a diameter of about an arm's length, which I saw two years since at the home of the Archbishop of Corfu, and still another I have recently seen about the same size or about one arm's length in diameter, which had been presented to His Excellency the Duke of Paliano." He adds that he had made careful geographical computations in his investigations, employing the last-named sphere. As to his method of procedure in his studies he states that "first of all having placed before me a solid sphere of about three feet in diameter, the most exact I have been able to find among those referred to above, namely, the one with the equinoctial circle and with the meridian passing through the Canaries of the Fortunate islands where Ptolemy located the prime meridian, I have divided it into four equal parts--two northern and two southern." It seems probable that the globe here referred to is that which he stated belonged to the Cardinal of Urbino, and which he noted was larger than was that belonging to Cardinal Viseo or to the Cardinal of Carpi, the diameter of which he stated to be an arm's length. Piccolomini gives us no intimation as to the authorship of the five globes he says he examined. He adds an interesting word concerning the character of the globe of Cardinal Carpi, seeming to imply that it was not a printed globe, since it represented "mountain elevations." We perhaps are justified, says Fiorini, in concluding from this and other evidence that the maps on these globes were not printed, since they were of very large size, and we know that Mercator's globes 41 cm. in diameter were then considered to have special value because larger than others constructed in a similar manner, that is, having their maps engraved or printed.
