a tablet of stone, which, after the Deluge, was brought to Phoenicia and Greece by Cadmos. A long section of the text is devoted especially to the letter Waw and its Greek equivalent, Digamma (called Episemon in the treatise), the numeral sign for "6". This sign is interpreted as a special symbol of Christ. At a later point in the text, this idea is further connected to the interpretation of all three extra-alphabetic numeral signs of Greek ("Episemon" for 6, Koppa for 90, and Sampi for 900) as symbols of the Holy Trinity, i.e. Christ, the Holy Ghost and God the Father respectively. The final chapters of the treatise engage in speculation about more general topics, including the history of mankind, whose key events are related symbolically to the sequence of vowels and consonants in the alphabet, a discussion of Christology dealing with issues related to the Council of Chalcedon, and reflections upon the name of Adam.
