Hello everyone,
I’m using a Bell’s Illustrared Classics edition of Caesar and one of the explanations strikes me as odd.
This is the sentence is question:
qui […] legatis nostris renuntiant se Biturigum perfidiam veritos revertisse, quibus id consilii fuisse cognoverint, ut, si flumen transissent, una ex parte ipsi, altera Arverni se circumsisterent.
The explanation of the sequence of tenses runs like this:
Here the Tenses will be best understood by tracing the growth of the sentence from its simplest form; thus, the thought of the Aedui was: > Biturigibus id consilii fuit, ut, si transissemus, circumsisterent. > Here > fuit > is Historic, and governs the Tense of > circumsisterent> , which is Historic because it depends upon > fuit> , and is Impf. because its action is not prior (but future) to that of > fuit> ; whilst > transissemus > is Historic because it depends immediately upon > cumsisterent> , and is Plupf. and not Impf. because its action is regarded as prior to that of > circumsisterent> . The next stage of the sentence represents the words of the Aedui to the legati: > Revertimus Biturigum perfidiam veriti, quibus id consilii fuisse cognovimus, ut, si transissemus, circumsisterent. > Finally Caesar describes the statement ('> renuntiant> '), with the effect of turning > revertimus > into > se revertisse> , and > cognovimus > into > cognoverint> . Examined in this way all cases will be accounted for in which a Plupf. is used for an apparently future action, e.g, ‘reliquissent,’ c. 17, 6, ‘ascendissent,’ c. 27, 2.
It is the last part that confuses me. I can’t seem to understand why it is that we turn revertimus to se revertisse (by the Rules of Oratio Obliqua: the main tense is indicative, so the subordinate clause becomes an acc. cum inf.) at the same time turning cognovimus to cognoverint and not to cognovisse (this may be explained by the Rules of the Consecutio temporum: depending on the primary tense, the subordinate verb becomes a perf. subjunctive).
But why would we apply one rule to one instance and a different rule to a parallel instance? I’ve definitely misidentified the issue. I hope someone could help me with this.
Thank you.
