I understood he had Masonic leanings earlier in life and no doubt Masonic sentiments influenced his values to some extent such as the idea of an exclusive brotherhood and the notion of gaining esoteric knowledge from hidden sources e.g. the Bible and the pyramids of Gizeh. His trick was to claim to be the conduit for interpreting these things.
Just one thing I noticed a couple of days ago; Russell's actual headstone bearing his photograph is only half finished, deliberately so, he wasn't short of cash!
As it happens my great grandfather's grave is the same with the dressing of the lower half of the stone left rough (in pink granite, Russell's favourite stone) and my grandfather with his unusual secular grave, was a high flying Mason.
In gravestone lore, to have a stone unfinished can mean going from material to a spirit life, especially if the inscription is not complete or it can be a Masonic symbol of the incompletion of the Temple building-- at least that was how I understood it to be.
Is there anyone here better versed in these things than I am?
Russell was not a practising Mason but he was not beyond using symbols as he saw fit or did someone else choose his headstone? I imagine the autocrat Russell chose his own.
