There are several Masonic myths about the Royal Order of Scotland:-
1. “That it is the oldest Masonic organisation.” Not true, but it is the oldest of the “Other Orders.”
2. “That it has the oldest Masonic ritual.” Only half true – it does have the oldest material in its ritual, but it is not Masonic in origin.
