1574/ 1599 Ruscelli Edition of Gastaldi's Map of the Arabian Peninsula

Giocomo Gastaldi (c. 1500 - October, 1566) was an Italian astronomer, cartographer, and engineer active in the second half of the 16th century. Gastaldi (sometimes referred to as Jacopo or Iacobo) began his career as an engineer, serving the Venetian Republic in that capacity until the fourth decade of the sixteenth century. During this time he traveled extensively, building a large library relating to voyages and exploration. From about 1544 he turned his attention to mapmaking, working extensively with Giovanni Battista Ramusio, Nicolo Bascarini, and Giovanbattista Pedrezano, as well ask taking private commission for, among others, Venice's Council of Ten. He is credited with the fresco maps of Asia and Africa still extent in the map room of the Doge's Palace. Gastaldi was also one of the first cartographers to embrace copper plate over woodblock engraving, marking and important development in the history of cartography. His 1548 edition of Ptolemy's Geographia was the first to be printed in a vernacular; it was the first to be printed in copperplate. As with his Swiss/German contemporary Münster, Gastaldi;'s work contained many maps depicting newly discovered regions for the first time, including the first map to focus on the East Coast of North America, and the first modern map of the Indian Peninsula. His works provided the source for the vast majority of the Venetian and Roman map publishers of the 1560s and 70s, and would continue to provide an outsize influence on the early maps of Ortelius, De Jode, and Mercator. Giocomo Gastaldi's 1548 edition of Claudius Ptolemy's Geographia - that is, La Geografia - . This appeared in six Latin editions in 1540, 1541, 1542, 1545, 1551 and 1552. According to Karrow, Munster based the text on the Latin translation of Willibald Pirkheimer, but he carefully collated it with previous editions, adding notes of his own. The first three editions contained 48 maps, consisting of 27 based on Ptolemy's ancient geography, and 21 maps based on modern geographical knowledge. The latter three editions contained 54 maps, comprised of the same ancient works but with six of the modern maps discarded, and twelve new ones added. For the collector, the modern maps are of sharpest interest. Some were based on Waldseemuller's geography, but many were based on Munster's own surveys and those of other European geographers whose assistance Munster had been able to enlist. Most of these would be reprised in Munster's magnum opus, Cosmographia Universalis. A disproportionate number of Munster's modern maps show contemporary geographical knowledge of the their respective areas for the very first time: The first map to show the continents of the Western Hemisphere; the first map to focus on the continent of Asia; the first modern map to name the Pacific Ocean. Even in cases where earlier maps exist, Munster's works very often remain the earliest such acquirable by the collector. More by this mapmaker...

Girolamo Ruscelli (1500 - 1566) was an Italian polymath, humanist, editor, and cartographer active in Venice during the early 16th century. Born in Viterbo, Ruscelli lived in Aquileia, Padua, Rome and Naples before relocating to Venice, where he spent much of his life. Cartographically, Ruscelli is best known for his important revision of Ptolemy's Geographia, which was published posthumously in 1574. Ruscelli, basing his work on Gastaldi's 1548 expansion of Ptolemy, added some 37 new "Ptolemaic" maps to his Italian translation of the Geographia. Ruscelli is also listed as the editor to such important works as Boccaccio's Decameron, Petrarch's verse, Ariosto's Orlando Furioso, and various other works. In addition to his well-known cartographic work many scholars associate Ruscelli with Alexius Pedemontanus, author of the popular De' Secreti del R. D. Alessio Piemontese. This well-known work, or "Book of Secrets" was a compilation of scientific and quasi-scientific medical recipes, household advice, and technical commentary on a range of topics that included metallurgy, alchemy, dyeing, perfume making. Ruscelli, as Alexius, founded a "Academy of Secrets," a group of noblemen and humanists dedicated to unearthing "forbidden" scientific knowledge. This was the first known experimental scientific society and was later imitated by a number of other groups throughout Europe, including the Accademia dei Secreti of Naples. Learn More...
