COURSE TUTOR: Prof Bill Sherman (Director and Professor of Cultural History)

The purpose of this short course will be to offer a systematic introduction to secret communication—in theory and in practice—stretching from the birth of printing to the advent of the computer. Through a combination of illustrated lectures and close examination of primary texts, we will learn how the field of cryptography was one of the great achievements of Renaissance culture. The 16th- and 17th-century books on the subject—by Johannes Trithemius, Gustavus Selenus, John Wilkins, Athanasius Kircher and others—put the study of codes and ciphers onto solid footing. And many of the technical inventions involved in encryption—including the Alberti disk, the Cardan[o] Grille, the Vigenère table and Bacon’s biliteral cipher—carry the names of leading Renaissance figures. But we will go deeper to see how the field left its mark on many aspects of Renaissance culture, including the development of diplomacy and the waging of war, the creation of a postal system, the birth of short-hand and sign-language, and the search for hidden meanings in art and literature. We will end by exploring the surprising role played by Renaissance ciphers in the making of modernity.

The course will be taught across five two-hour classes online via the Warburg Institute’s Zoom platform. Each session will have time for discussion. Reading lists will be made available to registered students.
