Vulcan was a sun deity who was associated with
fire, thunderbolts, and light. The festival in honour of him was called the
Vulcania in which human sacrifices were offered. "According to Diel, he bears a
family relationship to the Christian devil.' It is fascinating to know that he
married Venus, another name for Lucifer or the devil. What is even more
interesting is that Vulcan is adored in Masonry under the name of Tubal Cain. In
the Masonic Quiz Book the question is asked: "Who was Tubal Cain?" The answer
is: "He is the Vulcan of the pagans.''
In Masonry, Tubal Cain is the name of the password for the Master Mason (or third) degree.
Listen to what occultist and Mason, Manly Palmer Hall, has to say:
"When the Mason learns that the key to the warrior on the block is the proper application of the dynamo of living power, he has learned the mastery of his craft. The seething energies of Lucifer are in his hands and before he may step onward and upward, he must prove his ability to properly apply energy. He must follow in the footsteps of his forefather, Tubal-Cain, who with the mighty strength of the war god hammered his sword into a ploughshare.''
There is also a sexual connotation associated with Vulcan and Tubal Cain. Former Mason, Bill Schnoebelen, explains:
"For Masons who wish to conceal their membership from non-Masons, but still advertise it to their Lodge brothers, there is a special pin (or tie tack) they can wear. It looks like an upside down golf club with two balls near the top....Many people assume the person is a golfing enthusiast, but it is actually a visual Masonic pun.
"This is called the 'Two Ball Cane,' and is a pun on the secret password of a Master Mason, 'Tubalcain (sic).'...It is also an all-too-obvious pun on the 'god' of Masonry, the male reproductive organ. Nice, eh?...especially when many men wear these wretched things to church on Sunday!"-- Masonic and Occult Symbols Illustrated, pp. 233-238.  "Peace" Sign
