<Καὶ τόδε Φωκυλίδεω·> χρήστης κακοῦ ἔμμεναι ἀνδρός φεύγειν, μή σέ γ’ ἀνιήσηι παρὰ καιρὸν ἀπαιτέων.
I’m puzzled by the infinitives here. To begin with, how can χρήστης possibly fit with any of them, given that it is not in the accusative?
It looks as if φευγειν is being used as an imperative (well attested in Homer). “Avoid being a bad man’s debtor.” It’s in the epic meter. (See if you can figure it out.)
Thanks! I hadn’t known that infinitive can have the force of imperative in Greek (although, interestingly, it does have it in Russian).
But why the nominative χρήστης (not the accusative) with ἔμμεναι?
I have no knowledge of Greek meter, unfortunately.
Смотрите Черного, 126, d: подлежащее и имя сказуемого ставится в именительном падеже, если инфинитив заменяет императив во во втором лице,
Не знаком с этим источником, но спасибо!
Греческiй синтаксисъ гимназическаго курса, Э, Черный, After Smyth, this is the best practical grammar of Greek.
Thanks! But it doesn’t have more than Smyth does, does it?
I’ve checked it out, quite impressive! yet the index does not seem as helpful as in Smyth.
it has many fine details Smyth skips.
But why the nominative χρήστης (not the accusative) with ἔμμεναι?
I have no knowledge of Greek meter, unfortunately.
It’s like “Try to be a man,” or even “I want to be president.” No accusatives, nothing but nominatives.
No “fine details” are needed. The imperatival infinitive works like a regular imperative, that’s the only “detail” you need to know. Plenty of examples in Homer. And I’m sure everything will be in Smyth.
And I won’t answer any more questions from you until you can recognize hexameters! 
Perhaps someone will scan the fragment for you. Any takers?
OIC, it’s because the (implied) subject is in the nominative/vocative. Thanks! (To recognize meters I first need to be able to recognize the vowel length, which, unfortunately, I had not been trained to memorize when learning new words.)
<Καὶ τόδε Φωκυλίδεω•> χρήστης κακοῦ ἔμμεναι ἀνδρός
φεύγειν, μή σέ γ’ ἀνιήσηι παρὰ καιρὸν ἀπαιτέων
the second line scanning is wrong so what is the correct one?
Tugodum, If you know the metrical scheme the quantities reveal themselves. You don’t really need to know them beforehand.
CP, That’s basically right. You’re evidently bolding the long vowel in the first element of each foot (the longum). If that is what you’re doing, your only mistake is in ἀνιήσηι, where the first -ι- is long, the first syllable of the foot, but the -η- constitutes the foot’s second half (the biceps in Maas’s terminology).
This helps us recognize that the verb in question is ανιάω, the -ι- being long in Homer.
This second line has a 4th-foot caesura, not the more usual 3rd-foot one. When reading hexameters it’s always a good idea to aim for the caesura, where the verse tends to break. The first line picks up after the 3rd-foot caesura, as you recognized.
So “Avoid being a bad man’s debtor, in case he pester you, demanding repayment at an inconvenient time.”
Still good advice, as I sit here with an overdue bill on my desk.
Thanks, Michael. My other difficulty is that to motivate myself to learn the meters I need a way to learn to read out loud the way the Greeks did, not stressing but lengthening the proper syllables.
