Throughout the sixteenth and seventeenth centuries, the edges of Europe were under pressure from the Ottoman Turks. This book explores how Shakespeare and his contemporaries represented places where Christians came up against Turks, including Malta, Tunis, Hungary, and Armenia. Some forms of Christianity itself might seem alien, so the book also considers the interface between traditional Catholicism, new forms of Protestantism, and Greek and Russian orthodoxy. But it also finds that the concept of Christendom was under threat in other places, some much nearer to home. Edges of Christendom could be found in areas that were or had been pagan, such as Rome itself and the Danelaw, which once covered northern England; they could even be found in English homes and gardens, where imported foreign flowers and exotic new ingredients challenged the concept of what was native and natural.
