quo, relative pronoun, ablative of time within which??

Here is a fragment from Moriae Encomium, by Erasmus. It contains a problem I finessed earlier when I read this.

Superioribus diebus cum me ex Italia in Angliam recepissem, ne totum hoc tempus quo equo fuit insidendum amusois et illitteratis fabulis tereretur. . . .

I’m particularly concerned with quo in “hoc tempus quo equo fuit insidendum”. Earlier, I had a lot of trouble with this quo, and gave up on it. I want now to read it as a relative pronoun, agreeing in gender and number with “hoc tempus,” but in the ablative case, on account of its use in the relative clause, specifically the ablative of time within which.

“hoc tempus quo equo fuit insidendum” could be translated, “this time, during which [quo] one had to be on horseback.”

How does this reading of quo look?

Yes, you’re correct. The quo is a relative pronoun in the ablative referring back to tempus. Remember to include the “totum” in your translation of the phrase!

Yes that’s it. quo lit. “at which.” In English we might say “when.”

Many thanks to Laurentius and mwh.
