The ancient Greeks, and the Spartans in particular, are said to have used this cipher … They wrapped a cylinder in a piece of parchment to exchange… But one of the oldest ciphers is the Scytale cipher.It was used by the Greeks within their military operations, and where they would create a cylinder of a given radius, and wrap a ribbon around it. In modern cryptography techniques, the scytale can be replaced with appropriate matrix system. The Scytale (pronounced Sy-tally) Cipher was very much used by the Spartans and also by the ancient Greeks and Egyptians.  The idea is that you write a message on a ribbon or thin paper or papyrus (hello ancient world) wrapped around an object of a certain diameter, and then to decipher it you need to wrap the ribbon around another object of the exact same circumference so that the letters line up and you can decipher the message.  While this wasn’t super secure, in the ancient world it might have been just “good enough” especially during times of war. THE SCYTALE In cryptography, a scytale is a tool used to perform a transposition cipher. It is worth noting that transposition remains an important component of modern cryptographic algorithms due to its tremendous efficiency. As simple as the Scytale is, it’s invention paved the way for greater, more sophisticated, and complex methods of encryption. they invented a unique type of cryptography. Using the similar approach, the message can be ciphered using that method. Encryption can be traced back to the hieroglyphics of ancient Egypt around 3000 B.C. The Scytale Cipher. Scytale. It consisted of a polygonal rod or cylinder, around which was wrapped a piece of parchment. Scytale cipher is one of the transposition ciphers. These two letters are now the key. This was really fun to do!  I tried it out a couple of times with my two nephews and they loved it as well.  Simple and ingenious and probably not super effective as far as encryptions go since you don’t really need something the exact same diameter to break the code, just a little imagination (think Wheel of Fortune) and patience.   Either way, it illustrates the point and is a nice parlor trick.
