The Roman College of Artificers had certain operating features, such as being a mini-government operating under its own statutes, exercising the power of making contracts as a corporation would, with immunity from taxation. Its meetings were held in privacy, in similarity to the exoteric schools of the philosophers. It places its members into one of three classes, corresponding to the three levels of membership in modern Masonry. It also admitted into its ranks men who were not strictly speaking operative Masons by employment. This closely parallels the much later situation in late Medieval Masonry, when operative lodges gradually admitted gentlemen of learning, they being considered the first “speculative” Masons. Finally, they used a symbolic “language” allegorically drove from Masonic implements, and they conferred on their initiates secret modes of fraternal recognition.
As the Roman Empire declined, the Comacini Masons continued on a similar course, to them, we owe the development of the Romanesque style of architecture in about 600 A.D. This style has roots in Germany, France, and England. In similarity to our modern Masonic system, the Comacini had Masters, Wardens, signs, tokens, grips, passwords, and oaths of secrecy and fidelity.
Next we encounter the legendary establishment in England of rules for proper Masonic behavior. About 926 A.D., according to the Regius Poem from the late 1300s, Athelstan, an early Danish King of England, together with his brother Edwin, gathered Masons and their charters and rules of behavior from many European jurisdictions; these were unified into a code of conduct for the wide-area around Your, England Athelstan also granted the Masons a royal charger officially recognizing the Masonic Guild. This Guild carried out many functions of molder labor unions — it set uniformed waged, it trained apprentice stonemason, and it encouraged Masons to look out for each other. It also protected the trade secrets that made Masons the most highly-paid workers in Europe. Finally, Masonic guides developed and employed seated signs of fraternal recognition — signs that a Mason traveling to a distant building site might use to prove that he had been properly trained during an extensive apprenticeship.
My point here is that all of the behavioral influences occurred well before the middle Medieval Period when operative masons were employed by the Cistercian Monks to erect Europe’s magnificent cathedrals. Thus, it is not surprising that allegorical Masonic symbols do not include Medieval symbols, such as the Flying Buttresses of great cathedrals, but instead include simple tools (compasses, spare, plumb), and focus on ancient edifices, such as the Great Pyramid, with the All-Seeing Eye of God superimposed on it, and King Solomon’s Temple, with its ending staircase and Middle Chamber.
