Description: While there are many surveys of cryptography, none pay any attention to the volume of manuals that appeared during the seventeenth century, or provide any cultural context for the appearance, design, or significance of the genre during the period.Through close readings of five specific primary texts that have been ignored not only in cryptography scholarship but also in early modern literary, scientific, and historical studies, this book allows us to see one origin of disciplinary division in the popular imagination and in the university, when particular broad fields â " the sciences, the mechanical arts, and the liberal arts â " came to be viewed as more or less profitable.
