This challenging book argues that a new way of speaking of mathematics and describing it emerged at the end of the 16th century. Leading mathematicians began referring to their field in terms drawn from the exploration accounts of Columbus and Magellan. Many of those who promoted the vision of mathematics as heroic exploration also played central roles in developing the most important mathematical innovation of the period?the infinitesimal methods, which the author shows was no coincidence.

The early modern map has come to mark the threshold of modernity, cutting through the layered customs of Medieval parochialism with its clean, expansive geometries. Re-thinking the role played by mathematics and cartography in the English seventeenth century, this book argues that the cultural currency of mathematics was as unstable in the period as that of England's controversial enclosures and plantations. Reviewing evidence from a wide range of literary and scientific; courtly and pragmatic texts, Edwards suggests that its unstable currency rendered mathematics necessarily rhetorical: subject to constant re-negotiation. Yet he also finds a powerful flexibility in this weakness. Mathematized texts from masques to maps negotiated a contemporary ambivalence between Calvinist asceticism and humanist engagement. Their authors promoted themselves as artful guides between virtue and profit; the study and the marketplace. This multi-disciplinary work will be of interest to all disciplines affected by the recent 'spatial turn' in early modern cultural studies, and particularly to students and researchers in literature, history and geography.
