The Wikipedia page also mentions the Renaissance practice of
Chronograms , where the letters I, V, X, L, C, D, and M are extracted from a text, to form a number.
This would be a typical FD trick. There might be something hidden in the codex or The Dark Wheel?
This interested me greatly as never heard of it before, just another thing learned from this thread. Anyway:

So we might have some time to wait yet, taking off any combos of U=V, J=I, W=X & Y=II takes off 61 so
3392 or
3455. Bit surprised its still relatively close at all though as in the34th / 35th Century so there may be something in it somewhere with a bit of subtracting somewhere. Taking out the 'negative' statements gives:

Both too late even for the first known mention. But again close. Probably co-incidence just seems strange that a 'random' text gives dates in the right timeframe generally.
