In the sentence of Ars Amatoria 1,211-212, I want to know the meaning of 'nec tantum siqua rogabit' and the tense of 'nescieris'.
And also what's the meaning of the Latin phrase below.
Quam miserum est, ubi consilium casu vincitur.
In “Omnia responde, nec tantum siqua rogabit;/Et quae nescieris....” (Ovid, Ars Amatoria 1,221-222) the sentence "nec tantum siqua rogabit" literally means:
”..not (nec) only (tantum) if (si-) some (-qua” which stands for “aliqua” that drops the “ali” as it is preceded by “si”) [girl] (which is understood) will ask [you] (rogabit)...”, i.e.: ”not only if some girl will ask you...”.
As for "nescieris", it is the future perfect of “nescio” and literally means: “you shall not have known”.
So, “Omnia responde, nec tantum siqua rogabit;/Et quae nescieris .... refer” means:
”Answer to all questions not only if some girl will ask you something; also, tell what you maybe will not know, just as if you knew it well “, just as I have written in one of my previous answer to you.
As for “Quam miserum est, ubi consilium casu vincitur!”, which is a saying that we read in Publilius Syrus, a Latin writer of maxims, flourished in the 1st century BC, it means:”How sad it is, when prudence is defeated by the accident!", i.e. “How wretched it is when a good plan is defeated by an accident!”
