Real World article(written from a Production point of view)
Referenced multiple times in documentation from the making of Star Trek, Vulcan was a god in Roman mythology.
An early version of the nonsense poem "Saturn Rings", from the final draft script of the Star Trek: The Original Series episode "Charlie X", included the line, "Vulcan's helmet on my head."
Also, in the first draft script of the Star Trek: Enterprise episode "Strange New World", Tucker asked T'Pol how the planet Vulcan had ended up with "the name of an ancient Earth god."
