Detailed Photographic Facsimile of "undoubtedly the most important record of the Magellan expedition."
MyOldMaps gives the following summary of this very important early world map:
This large map is attributed to Giovanni [Juan] Vespucci, born in Florence in 1486, who was the nephew of the great navigator Amerigo Vespucci. The latter, who collaborated in 1512 by Juan Diaz de Solis, pilot major of the Casa de la contratación Seville which was responsible for forming the new map Oficial del Estado (Padrón real), and he became pilot major in 1513; in 1515 it was part of the junta in charge of correcting the navigation chart (carta de navegar) as a result of the review of Raya, the line found after the bull of Pope Alexander VI sent to the Spanish royal May 4, 1493 (the Treaty of Tordesillas), which established the division of the world into two spheres of influence, Spanish and Portuguese. The Geocarta Nautica Universale [Great Universal Maritime Chart], as defined in the recording inventory) is the first known map, drawn before the Junta de Badajoz (before 1524), which takes into account the results of the circumnavigation of the globe by Magellan’s expedition (1522); therefore it is the first map that shows the complete representation of the Pacific Ocean.
The map is now housed in the Royal Library of Turin.
The Edward Luther Stevenson Collection
Edward Luther Stevenson was among the most important scholars of early cartography active at the end of the 19th century and the first half of the 20th. He was responsible for numerous cartobibliographic books, including the first translation of Ptolemy to English, as well as a series of impressive facsimile maps produced while he was at the Hispanic Society of New York. Dr. Stevenson viewed facsimiles as integral to the study of early cartography, and he committed himself to building an unparalleled collection of photographs of early maps and globes. Much of his collection was donated to Yale University after his death (click on the title link above for about that), but the present item comes from a large collection of photos, manuscripts, and related material that were part of Stevenson's library, but were not donated to Yale. It is truly an impressive collection and many of the items, though reproductions, have serious antiquarian merit. As Alexander O. Vietor said about Stevenson collection that went to Yale "this is the stuff of which great libraries are made."
