Here is the definition of another word that is used in Masonic Ritual, but is not common outside the Lodge room.


The Entered Apprentice hears this word as a description of ‘the form of the lodge’. Every Entered Apprentice I’ve spoken with after his Initiation admits that he has never before heard the word parallelpipedon. And he admits he has no idea what it means!

I try to help with the explanation that it is a shape defined in the first English translation of the works of the geometrician Euclid. It is a shape or space having six sides of which the opposite sides are parallel.

And I can add that in this year of 2020, the word is now 550 years old! A detailed explanation of my research is accepted for publication in Ars Quatuor Coronati Volume 133, to be released in November 2020. You may subscribe to receive it at
