Thomas Brierley's gravestone in Mellor Churchyards in Cheshire is a good example of the use of the Pigpen Cipher by Freemasons in the 18th century. Notice the Masonic square and compass symbols. It is difficult to decipher the text due to the weathering of the gravestone. The ciphertext also seems to use a non-standard symbol for the letter "S". The text at the head of the stone appears to say "Thomas Brierley made his ingress July 16th 1785".
The meaning of the ciphertext at the foot of the gravestone appears to be "Holiness of the Lord"
