Description

This finely colored woodcut map from Benedetto Bordone’s Libro di Benedetto Bordone nel qual si ragiona de tutte l’isole del mondo, first published in Venice in 1528, illustrates the islands of Porto Santo and Madeira in the Atlantic Ocean. The map provides a striking representation of these Portuguese islands, which had become pivotal outposts in the age of exploration and transatlantic navigation. 

Located to the northeast of Madeira, Porto Santo is depicted with notable detail, showing its hilly terrain and small settlements. Discovered by the Portuguese in 1418, Porto Santo became one of the first stepping stones in Portugal’s maritime expansion. The island’s depiction in Bordone’s map reflects its significance during the early 16th century, serving as a refuge for sailors and a site of agricultural development. The strategic importance of Porto Santo lay in its proximity to the main island of Madeira, which served as a hub for the cultivation of sugarcane, a key commodity that drove European interest in Atlantic territories. 

The island of Madeira is presented with its rugged coastline and elevated interior, capturing the island’s dramatic topography. Settled soon after Porto Santo in 1419, Madeira quickly grew into a thriving colony, particularly with the introduction of sugarcane by the Portuguese. By the time of Bordone’s publication, Madeira’s sugar industry had gained international recognition, attracting merchants from across Europe. The map marks the location of “Madera,” indicating the island’s central role in trade and agriculture. Madeira’s wealth from sugar production and its position along the Atlantic trade routes established it as a key point in the Portuguese maritime empire. 

The islands of Porto Santo and Madeira played crucial roles in the broader narrative of European exploration. As part of the Portuguese empire, these islands were among the earliest outposts that expanded Europe’s reach into the Atlantic, setting the stage for future ventures to the Americas and beyond. The settlements and agricultural ventures depicted on this map underscore the islands’ transformation from isolated landmasses into economically vibrant colonies. 

Historical Overview of Isolario Mapping

The isolarii, or "island books," emerged as a fascinating and enigmatic genre during the Renaissance. These works do not fit neatly into the conventional categories of map or chartmaking, but instead represent a unique "underground" geographical culture. Flourishing in the experimental and tolerant climate of the Renaissance, isolarii played an integral role in the early development of the history of cartography.

Historians of cartography have offered varied interpretations of the isolarii, reflecting their complex and multifaceted nature. Some view them as early regional island atlases, while others categorize them as emerging from the travel literature or as products of the geopolitical context of the Aegean islands, Crete, and Cyprus. Additionally, isolarii have been seen as expressions of Renaissance individuality, primitive tourist guides, and carriers of political content. These diverse interpretations highlight the genre's position at the crossroads of geographical, historical, travel, and nautical literature.

  • The Genre of Isolario

Isolario refers to manuscript or printed atlases, typically comprising maps of islands and sometimes coastal areas, organized thematically. These works, often described as "books of islands" or "island navigations," evolved from the geographical traditions of the ancient world, where islands held a significant place in geographical literature. The isolario can be seen as a cosmographic encyclopedia of islands, fulfilling various learned, practical, and informational needs from the early fifteenth to the late seventeenth centuries.

Travelers' memoirs, chronicles of sea voyages, and military accounts often influenced isolarii, contributing to their content and shaping their form.  The isolario, with its maps and encyclopedic nature, represents a specific genre that thrived in the Mediterranean, particularly in Florence and Venice.

  • The Birth of the Genre: Florence, Fifteenth Century

The isolario genre was born in the fertile intellectual environment of early Florentine humanism. The first significant work of this genre was Cristoforo Buondelmonti's Liber insularum archipelagi, created around 1420. This work, which includes maps and descriptions of seventy-nine places in the Ionian and Aegean seas, reflects the geographical interests of Florentine humanists. Buondelmonti's isolario combines historical geography and personal travel narrative, offering a rich tapestry of mythological, historical, and contemporary observations.

Buondelmonti's work set the template for future isolarii, blending cartography with narrative descriptions and personal anecdotes. His maps, though not always accurate, were among the first to systematically depict the Greek islands, influencing subsequent cartographers and isolarii authors.

  • The Golden Age: Venice, Sixteenth Century

The invention of printing significantly expanded the audience for isolarii. One of the first printed isolarii was Bartolommeo dalli Sonetti's Isolario, published around 1485 in Venice. This work, containing forty-nine maps and accompanying sonnets, marked a new phase in the genre's development. Bartolommeo's isolario, influenced by Buondelmonti's earlier work, catered to both scholarly and popular interests, combining practical navigational information with poetic descriptions.

The sixteenth century saw further developments in the genre, with works such as Benedetto Bordone's Libro... de tutte l'isole del mondo (1528), which aimed at a broader readership. Bordone's isolario, with its 111 maps, provided both practical information for mariners and enjoyable reading for the general public. This period also witnessed the rise of nautical isolarii, exemplified by the Turkish admiral Piri Re'is's Kitab-i bahriye, a comprehensive and detailed navigational guide to the Mediterranean coasts and islands.

  • Benedetto Bordone

Benedetto Bordone further transformed the isolario genre with his Libro... de tutte l'isole del mondo, first published in Venice in 1528. Bordone's isolario contained 111 maps, 62 of which depicted Greek islands, heavily influenced by earlier works of Buondelmonti and Bartolommeo dalli Sonetti. Bordone aimed his work at a broad, nonspecialist readership, blending practical maritime information with entertaining historical and mythological narratives. His work went through numerous editions, underscoring its popularity and impact.

Bordone's work is notable for being the first atlas to cover the entire world without relying on Classical geography. Prior to this atlas, only the Waldseemüller / Ptolemy Geographia, which was essentially a Ptolemaic atlas despite incorporating "modern" maps, had attempted to chart lands beyond the Old World. However, with this work, Bordone breaks from this tradition, mapping all the previously unknown regions of the world, including specific areas of America, and basing the book on contemporary isolario data rather than on Ptolemaic sources.

Bordone's work expanded the geographical scope of the isolario far beyond the traditional waters of the Mediterranean and Aegean, introducing the genre to the North Atlantic, Caribbean, African and Asian Coastlines and featuring many important firsts, including the notably the first mapping of Japan.   Bordone was the first isolario publisher to truly see the genre as a means of depicting the entirety of the known world. 

Benedetto Bordone Biography

Benedetto Bordone (1460-1531) was a polymath who was born in Padua and worked in Venice. He was an illuminator, engraver, miniaturist, editor, and geographer. It is possible he made the first globe in Italy. His most famous work is the Isolario, or Book of Islands, which included many of the earliest printed maps of islands in the New World.

Bordone, a prominent Venetian manuscript editor, miniaturist, and cartographer, was born in Padua, a city that was then part of the Republic of Venice. Although his exact date of birth remains unknown, historical records indicate that his parents married in Padua in 1442, and he himself was married in 1480. Bordone's contributions to the field of cartography, particularly through his seminal work, Isolario, have cemented his legacy as a pivotal figure in the Renaissance cartographic tradition.

Bordone's most renowned work, Isolario (The Book of Islands), printed in Venice in 1528, is a comprehensive compilation that describes all the known islands of the world. The book offers detailed accounts of each island's folklore, myths, cultures, climates, geographical situations, and historical narratives. It stands as a testament to the popularity of the isolario genre in 15th and 16th century Italy and serves as an illustrated guide for sailors, incorporating the era's latest transatlantic discoveries.

One of the notable features of Isolario is an oval depiction of the world, a map type invented by Bordone. This innovation was later formalized into the equal-area elliptical Mollweide projection three centuries afterward. Bordone's map portrays a distorted view of the New World, showing only the northern regions of South America and depicting North America as a large island labeled Terra del Laboratore (Land of the Worker), a likely reference to the region's active slave trade during that period, which also influenced the name Labrador.

The book also contains the earliest known printed account of Francisco Pizarro's conquest of Peru, making it a significant historical document. Among the numerous woodcut maps included in Isolario, twelve are dedicated to the Americas. These maps feature a plan of "Temistitan" (Tenochtitlan, modern Mexico City) before its destruction by Hernán Cortés, and a map of Ciampagu, the earliest known European-printed map of Japan depicted as an island.

Benedetto Bordone's familial connections are also of interest; he is reputed to have been the father of Julius Caesar Scaliger, a noted classical scholar, and the grandfather of Joseph Justus Scaliger, who is recognized as the founder of the science of historical chronology. The original maps from Bordone's Isolario are highly valued today for their historical significance and intricate craftsmanship. Through his work, Bordone has left an indelible mark on the history of cartography, providing invaluable insights into the geographical knowledge and cultural perceptions of his time.
