The art of the code–code making and code breaking—remains shrouded in mystery and seems locked away in the murky realms of military intelligence, spies, and secret services. Yet codes affect virtually every area of our lives, providing security, protecting identity, and enabling us to connect via the Internet across global boundaries. This lavishly illustrated encyclopedia surveys the history and development of code making and code breaking in all areas of culture and society-from hieroglyphs and runes to DNA, the Zodiac Killer, The Da Vinci Code, graffiti, and beyond. Beginning with the first codes, including those found in the natural world and among ancient peoples, the book casts a wide net, exploring secret societies, codes of war, codes of the underworld, commerce, human behavior, and civilization itself. Editor Paul Lunde and an extraordinary group of specialists have compiled the most comprehensive and complete collection of codes available. Visually stunning and packed with fascinating details, The Book of Codes tells the complete story of codes at a time when they have become fundamentally important to our lives.

Paul Lunde is the author of Islam: Faith, Culture, History and Organized Crime: An Inside Guide to the World's Most Successful Industry and the coauthor of A Land Transformed, a history of Saudi Arabia.
