Can multiple singular things act as a collective subject? I am trying to understand the following expression from Horace:
fama decus divitiis parent
So, fama and decus are both singular nominatives. However, the verb of the sentence is third person plural, parent (they appear). So, it appears (paret) that fama and decus seem to be acting as a collective subject of the sentence, so take a plural form of a verb. Is that right? If so, then the sense of the sentence seems to be,
reputation and honor appear with wealth.
Also, should I treat divitiis as ablative with cum understood, or should I treat it as ablative of agency? It changes the meaning. So, does it mean "with wealth" or "by wealth"?
