It was allegedly the work of the infamous pirate, Olivier Levassuer, also known as The Hawk (La Buse).īourrel had identified the cipher, which was a form of pigpen, and translated that into plaintext. In 1934, a well-respected historian by the name of Charles Bourrel de la Roncière published a book about a cryptogram he had deciphered. It can also be found on Masonic medals, certificates, tokens and even gravestones. There are still surviving examples of letters written using the cipher from the 16th Century. Pigpen Cipher is used extensively in Freemason documentation. Some of the more interesting uses of the cipher are: Freemasons Because it doesn’t need any specialist equipment to code or decode, it has been used by many people to hide the meaning of the notes they’ve left in their diaries or other documentation. They are perhaps the most famous and prolific users of this cipher, which is why it is often referred to as the Freemason’s Cipher. The Freemasons began to use the Rosicrucian Cipher, and then Pigpen.

Suspected members include infamous alchemist, John Dee. The order claimed to be, ‘Built on the esoteric truths of the ancient past’ however even at the time many viewed the papers as a hoax. The Rosicrucian Order was a group which emerged in the early 17th century when they published a series of papers. It is a similar cipher to Pigpen, but it uses only square grids to encode the letters. In 1531 he published, ‘Three Books of Occult Philosophy’, and in that he describes a version of what would eventually be called the Rosicrucian cipher. Heinrich Cornelius Agrippa was a German with many talents, and one of those was writing about the occult.

Whether there is a dot in the shape will guide you to which grid you should be looking at.

To decode, you simply locate the shape you are looking at on the diagram to find the letter. To encode a message to Pigpen, find the letter you wish to encrypt and draw the lines that you see around it. The diagram below shows the key used for encrypting and decrypting something written in Pigpen Cipher. The cipher has been in use since the 1500s, and is also know by the names Masonic Cipher, Napoleonic Cipher, Tic-Tac-Toe Cipher, Pig Pen and Freemason’s Cipher. In other words, rather than using letters of the alphabet, you form words from geometric symbols. Pigpen Cipher is a geometrical monoalphabetic substitution cipher.
