To begin - The Royal Arch Degree can be briefly summarised as follows - In the Holy Royal Arch degree the candidate, a sojourner from Babylon, takes part in clearing the debris from the destruction of King Solomon’s Temple to start building the second temple, in so doing an Arch is discovered leading to the discovery of the Word that was lost by the untimely death of our master Hiram Abiff in the Master Masons degree.
So far, so good, now what about myths?
