I want to know the answer to the following question:
The duties of its grades is an example of what historic documents?
All the background I'm provided with is that "Alluding to the membership of a lodge of operative masons, they relate a mythologised history of the craft, the duties of its grades, and the manner in which oaths of fidelity are to be taken on joining.". Is that enough to answer the question?
Answer: no
