Troubadour
as if perhaps the narrator was a character, but is not a character. Does that make sense?
If done right. Juvenal does that. At least one of his satires reads as if "this is the opinion of Juvenal, talking to us, his readers". It reads like that almost up until the end, when Juvenal flips it and suddenly we are uncertain 'who' this narrator character is. Is he Juvenal? If so then Juvenal has revealed himself as a hypocrite. Or was he actually an invented character the whole time?
Whoever 'he' is, he present us with the picture of a wealthy Roman of senatorial class who pompously lectures us on the merits of a simple pastoral life in the countryside - only to reveal, at the last moment, that he is actually living the life of a cosmopolitan city dweller. Whoever the narrator is supposed to be, we are left in no doubt that his real life and the values he espouses are completely at odds with each other.
Was the narrator an omni-voice or the voice of a character? Juvenal leaves that question open to interpretation. Leaving the question open means the message is unclear. Deliberately so in my opinion. Is Juvenal extoling the virtues of a simple country life? Or is he exposing the hypocrisy of people who idealise a pastoral existence whilst making their livings in a big city? Or both? Clever writing.
