The cryptoquotes you see in the newspaper are actually examples of a kind of cryptography used in the Ancient World. Substituting each letter in a message with another, the message becomes unreadable (for example: "Darien Library" becomes "Gctlhq Oletctb" using the Caesar Cipher- used by Julius Caesar to communicate with his generals- that substitutes each letter for the one three positions away in the Latin alphabet.) This is your chance to learn to make and read these kinds of substitution ciphers!
