Gerhard Mercator (1512–1594) was the most important cartographer and globemaker of the 16th century. He is particularly remembered for his publication Atlas sive Cosmographicae Meditationes de Fabrica Mundi et Fabricati Figura (1595), and for his specific cylindrical map projection (1569), which is still used widely today. This book brings together the latest research on Mercator with a view to his sources and his relationships with other scientific disciplines and cartographers of his time, as well as his role in the wider worlds of Renaissance cartography and Humanism.

In Rhumb Lines and Map Wars, Mark Monmonier offers an insightful, richly illustrated account of the controversies surrounding Flemish cartographer Gerard Mercator's legacy. He takes us back to 1569, when Mercator announced a clever method of portraying the earth on a flat surface, creating the first projection to take into account the earth's roundness. As Monmonier shows, mariners benefited most from Mercator's projection, which allowed for easy navigation of the high seas with rhumb lines—clear-cut routes with a constant compass bearing—for true direction. But the projection's popularity among nineteenth-century sailors led to its overuse—often in inappropriate, non-navigational ways—for wall maps, world atlases, and geopolitical propaganda. Because it distorts the proportionate size of countries, the Mercator map was criticized for inflating Europe and North America in a promotion of colonialism. In 1974, German historian Arno Peters proffered his own map, on which countries were ostensibly drawn in true proportion to one another. In the ensuing "map wars" of the 1970s and 1980s, these dueling projections vied for public support—with varying degrees of success. Widely acclaimed for his accessible, intelligent books on maps and mapping, Monmonier here examines the uses and limitations of one of cartography's most significant innovations. With informed skepticism, he offers insightful interpretations of why well-intentioned clerics and development advocates rallied around the Peters projection, which flagrantly distorted the shape of Third World nations; why journalists covering the controversy ignored alternative world maps and other key issues; and how a few postmodern writers defended the Peters worldview with a self-serving overstatement of the power of maps. Rhumb Lines and Map Wars is vintage Monmonier: historically rich, beautifully written, and fully engaged with the issues of our time.

The story of discovery and mapmaking is one of pushing back shadows," writes Andrew Taylor, and "none in the last two thousand years achieved as much as Gerard Mercator in extending the boundaries of what could be comprehended." His life encompassed most of the turbulent, extraordinary sixteenth century, a time when revolutions would engulf religion, science, and civilization. Almost extinguished by the Inquisition, Mercator's genius lay in making maps, and his achievement did nothing less than revolutionize the study of geography. Appropriately for an era undergoing radical change, Mercator was full of contradiction, tied to knowledge and beliefs of the past while forging a new path. He never traveled beyond northern Europe, yet he had the imagination to draw the entire world anew and to solve a problem that had baffled sailors and scientists for centuries: how a curved Earth could be faithfully rendered on a flat surface so as to allow for accurate navigation. His "projection" was so visionary that it is used by NASA to map Mars today. Andrew Taylor has beautifully captured Mercator amidst the turmoil and opportunity of his times and the luminaries who inspired his talent-his teacher and business partner, Gemma Frisius; the English magus, John Dee; his benefactor, the Holy Roman Emperor Charles V, his cartographic collaborator, Abraham Ortelius. The World of Gerard Mercator is a masterful biography of one of the men most responsible for the modern world.

Publisher Description

In this beautifully conceived book, Ayesha Ramachandran reconstructs the imaginative struggles of early modern artists, philosophers, and writers to make sense of something that we take for granted: the world, imagined as a whole. Once a new, exciting, and frightening concept, “the world” was transformed in the sixteenth and seventeenth centuries. But how could one envision something that no one had ever seen in its totality? The Worldmakers moves beyond histories of globalization to explore how “the world” itself—variously understood as an object of inquiry, a comprehensive category, and a system of order—was self-consciously shaped by human agents. Gathering an international cast of characters, from Dutch cartographers and French philosophers to Portuguese and English poets, Ramachandran describes a history of firsts: the first world atlas, the first global epic, the first modern attempt to develop a systematic natural philosophy—all part of an effort by early modern thinkers to capture “the world” on the page.
