I agree, I think there is little doubt that Freemasonry took its rise, most certainly, from the existing societies or organisations of the day, certainly no less than the coat of arms from the Company of Masons, which we still use to this very day as part of the UGLE coat of arms, and of course they copied the officers roles as well.I think I quite like the quote by Daniel Beresniak in his book, Symbols of Freemasonry, when he said.
"...in the seventeenth and eighteenth centuries, Freemasons took their inspirations from the rites and customs of the Guild of Masons in order to give their work structure, organisation and symbols..."
Hence my suggestion that Anderson "stole" these things, but I am happy with the terms "adopt or adapt".
They say that "imitation is the highest form of flattery".
Sadly, I do believe however, that the early Operative Lodges (in England and possibly to some extent maybe Scotland), along with some of their customs, practices and history, has been lost at the expense of the success of Andersons invention.
Dare I say that I have often thought the the Operative system in Scotland which accepted Speculative or Gentlemen Masons (and which I believe predates Englands Acception ceremonies for Gentlemen) as members, eventually sold out to the Premier Grand Lodge, rather than continue their own practices.
I'd be interested in the views of other on that subject.
