Ruscelli, Girolamo

Girolamo Ruscelli (1500 - 1566) was an Italian polymath, humanist, editor, and cartographer active in Venice during the early 16th century. His work as a polygraph - a writer on many subjects, producing, editing, and copying content for the new printing industry - required erudition in a broad array of fields. 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 he published in 1561, with further editions as late as 1599.  Ruscelli's work represented a marked improvement on Gastaldi's 1548 Ptolemy, presenting both the ancient and modern maps in larger, more clearly-engraved examples. His edition also included maps not present in Gastaldi's Ptolemy, including the first double-hemisphere world map to appear in a Geography, the earliest mapping of the British Isles from an English source, and the notorious and influential Zeno map of the North Atlantic.  Ruscelli is also listed as the editor of 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, and perfume making.  Ruscelli, as Alexius, founded an "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.
