1688 Rosaccio / Moretti Woodcut Map of Eastern Europe and the Black Sea Region

Giuseppe Rosaccio (approx. 1530 - 1620) was a Venetian physician, astrologer, and geographer. He was born in the Venetian city of Pordenone, and graduated from the University of Padua having studied philosophy, medicine and law. He moved to seek his fortune in Tricesimo, where he worked as a physician and may have taught literature. His legal education led him to serve as a judge there in civil trials during the period between 1561 and 1575. 1607 found him in Florence in the service of Grand Duke Cosimo II (patron of Galileo). Rosaccio married, and had at least two children: Leonardo - who died on April 30, 1603 - and Luigi (also rendered as Alouisio), who collaborated with his father in his geographical work.

He was a prolific author, producing as many as forty works disseminating new knowledge (to a lay audience, using the Italian vernacular). These were mostly on the topics of astronomy and his primary interest, geography. He ventured afield on an array of subjects, including essays on Islam. He remains best known for his geographical texts, which were popular and republished in multiple editions. These included a 1598 edition of Ptolemy, a 1607 geography of Italy, and his final work - the 1610 Discorso nel quale si tratta brevemente della nobiltà, et eccellenza della Terra rispetto à Cieli, et altri elementi, was dedicated to Cosimo II and contained novel information on the American continent, including Drake and Cavendish' circumnavigations. This work included a map drawn by his son Alouisio. More by this mapmaker...

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. Learn More...
