Martin Waldseemüller

In 1506, the Gymnasium obtained a French translation of the Soderini Letter, a booklet attributed to Amerigo Vespucci that provided a sensational account of four alleged Vespucci voyages to explore the coast of lands recently discovered in the western Atlantic. The Gymnasium surmised that this was the "new world" or the "antipodes" hypothesized by classical writers. The Soderini Letter gave Vespucci credit for discovery of this new continent and implied that newly obtained Portuguese maps were based on his explorations. They decided to put aside the Geography for the moment and publish a brief Introduction to Cosmography with an accompanying world map. The Introduction was written by Ringmann and included a Latin translation of the Soderini Letter. In a preface to the letter, Ringmann wrote

"I see no reason why anyone could properly disapprove of a name derived from that of Amerigo, the discoverer, a man of sagacious genius. A suitable form would be Amerige, meaning Land of Amerigo, or America, since Europe and Asia have received women's names."[8]

Universalis Cosmographia, Waldseemüller's 1507 world map, which was the first to show the Americas separate from Asia.

While Ringmann was writing the Introduction, Waldseemüller focused on the creation of a world map using an aggregation of sources, including maps based on the works of Ptolemy, Henricus Martellus, Alberto Cantino, and Nicolò de Caverio. In addition to a large 12-panel wall map, Waldseemüller created a smaller, simplified globe. The wall map was decorated with prominent portraits of Ptolemy and Vespucci. The map and globe were notable for showing the New World as a continent separate from Asia and for naming the southern landmass America. By April 1507, the map, globe and accompanying book, Introduction to Cosmography, were published. A thousand copies were printed and sold throughout Europe.[9]

The Introduction and map were a great success, and four editions were printed in the first year alone. The map was widely used in universities and was influential among cartographers who admired the craftsmanship that went into its creation. In the following years, other maps were printed that often incorporated the name America. Although Waldseemüller had intended the name to apply only to a specific part of Brazil, other maps applied it to the entire continent. In 1538, Gerardus Mercator used America to name both the north and south continents on his influential map, and by this point, the name was securely fixed on the New World.[10]

After 1507, Waldseemüller and Ringmann continued to collaborate on a new edition of Ptolemy's Geography. In 1508, Ringmann travelled to Italy and obtained a Greek manuscript of Geography (Codex Vaticanum Graecorum 191). With this key reference, they continued to make progress and Waldseemüller was able to finish his maps. Completion was forestalled, though, when their patron, Duke René II, died in 1508. The new edition was finally printed in 1513 by Johannes Schott in Strasbourg. By then, Waldseemüller had pulled out of the project and was not credited for his cartographic work.[11][12] Nevertheless, his maps were recognized as important contributions to the science of cartography and were considered a standard reference work for many decades.[13]

About 20 of Waldseemüller's tabulae modernae (modern maps) were included in the new Geography as a separate appendix, Claudii Ptolemaei Supplementem. This supplement constitutes the first modern atlas.[14] Maps of Lorraine and the upper Rhine region were the first printed maps of those regions and were probably based on survey work done by Waldseemüller himself.[15]

The world map published in the 1513 Geography seems to indicate that Waldseemüller had second thoughts about the name and the nature of the lands discovered in the western Atlantic. The New World was no longer clearly shown as a continent separate from Asia, and the name America had been replaced with Terra Incognita (Unknown Land). What caused him to make these changes is not clear, but perhaps he was influenced by contemporary criticism that Vespucci had usurped Columbus's primacy of discovery.[16]

Waldseemüller was also interested in surveying and surveying instruments. In 1508, he contributed a treatise on surveying and perspective to the fourth edition of Gregor Reisch's Margarita Philosophica. He included an illustration of a forerunner to the theodolite, a surveying instrument he called the polimetrum. In 1511, he published the Carta Itineraria Europae, a road map of Europe that showed important trade routes and pilgrim routes from central Europe to Santiago de Compostela, Spain. It was the first printed wall map of Europe.[17]

In 1516, he produced another large-scale wall map of the world, the Carta Marina Navigatoria, printed in Strasbourg. It was designed in the style of portolan charts and consisted of 12 printed sheets.

The Paris Green Globe (or Globe vert), has been attributed to Waldseemüller by experts at the Bibliothèque Nationale, but the attribution is not universally accepted.

Waldseemüller died without a will on 16 March 1520 in Saint Dié in the Upper Rhenish Circle of the Holy Roman Empire, where he had served as a canon in the collegiate Church of Saint Dié since 1514.[18]
