In reading through Book VI of Vergil's Aeneid, I came across the following line:
851 tu regere imperio populos, Romane, memento
I believe this is translated as "you, Roman, remember to rule the people with authority", where memento is a future imperative. Evidently, future imperatives are used when the command is given for some point in the future. This got me thinking about the situations in which future imperatives could be used.
It makes sense for affirmative future imperatives to exist, because you could give someone instructions to do something for a later date. However, it seems that negative future imperatives would not really be necessary because you could just avoid giving any order or give a negative present imperative (I figure, chances are, if you don't want someone to do something today, you wouldn't want them to do it tomorrow).
Here are my questions:
- Do negative future imperatives exist?
- If so, what are some examples? (preferably from the Classical Latin works, but anything is fine)
- Would this construction be favoured over using a negative subjunctive or non with a periphrastic?
