In the collection of essays, God in the Dock, C. S. Lewis uses the word "mellontolatry," which is defined as "worship of the future." This is the first instance of the word I can find.
In other places, Lewis makes up words, but he explicitly says that he is coining a term. E.g, "Bulverism." But he uses "mellontolatry" as if it were a known, but rare, word.
A few years ago, I went on a determined hunt for the origin of this word. OED had nothing. The UT Austin library had a 7 or 8 volume dictionary and it had nothing. I enlisted one of the senior librarians (whose eyes lit up at the challenge) in the hunt. We found nothing preceding Lewis.
Today, Google have me this hit:
which also lists:
Pareltholatry – worship of the past
Nynolatry – worship of the present
Chronolatry – worship of time
and, frankly, I file that website under "too silly." All other hits derive from Lewis.
So that's my question: Did Lewis coin this word? If not, where did it come from?
