I’m reading The Greedy Queen by Annie Gray. The author quotes a court lady’s diary entry about the unfailing daily routine at Queen Victoria’s court, such as breakfast at a quarter to ten, tea at five thirty, and dinner at nine. Then the court lady says:
This routine never varies by a hair’s breadth, as soon a revolution as to drive in the morning and walk after lunch, and boiled beef on Thursday and ‘mehlspeise mit ananas’ on Friday recur with unfailing regularity.
The definition of “as soon as” given by the dictionaries doesn’t seem to fit this context and I’m confused about what “as soon a revolution as to” means. Is she saying that “to drive in the morning and walk after lunch, and boiled beef on Thursday and mehlspeise mit ananas on Friday” are also routines that occur regularly, or quite the contrary, that they seldom do those things?
