The compass relate to exact sciences. Probably engineering... Might as well be also related to freemasonry. The snek, though... Is purposely shaped like an"S". I am going to throw two possible guesses here.
One, and the most likely, this the symbol of an obscure and probably extinct chapter of the Freemasons.
Two, speculating the snake is related to the Rod of Asclepius somehow, this could represent a sort of joint college or guild of engineers and medics.
Where did you find this, Anon?
I recommend you to also post this to the paranormal, the history and humanities, and the random boards to find more opinions.
