Warren Ellis says: "BY REQUEST: Glycon was a snake god, according to the satirist Lucian, who provides the only literary reference to the deity. Lucian claimed Glycon was created in the mid-second century by the Greek prophet Alexander of Abonutichus. Lucian was ill-disposed toward the cult, calling Alexander the "oracle-monger" and accusing the whole enterprise of being a hoax—Glycon himself was supposedly a hand puppet.
More about Glycon.

Glycon is, of course, the preferred deity of Alan Moore."

I am currently reading Lost Girls and The Black Dossier from the League of Extraordinary Gentlemen. And and Snake has phallic references built-in. So I can put this.
