I have been collecting instances of Gnosis, the word itself rather than what it refers to. Have you ever wondered how many times the Greek word "Gnosis" appears (with some context, and not in duplicate texts) in the Coptic Gnostic texts found at Nag Hammadi? 134 times. And that is with clear evidence showing that it was a word that was translated into Coptic. In duplicate texts it is found translated in one version and not in another.
What is much more interesting than a mere quantity is examining the usage in the surviving contexts. To which has been added instances in other texts such as the Pistis Sophia, the Bruce Codex, and so on. With the Greek Hermetica thrown in. Well over two hundred instances all together. Yes, it is a task only a scholar would do, and probably only a Graduate Student. Yet it should make for an interesting part of my monograph on Gnosis. And I can't be accused of not being exhaustive, or exhausted.
