Pigpen code chart

The pigpen cipher (sometimes called the masonic cipher or Freemason's cipher) is a simple substitution cipher exchanging letters for symbols based on a grid. The scheme was developed and used by the Freemasons in the early 1700s for record-keeping and correspondence. The example key shows one way the letters can be assigned to the grid.
