ἑσπέρας

Eduard Johnson at p. 26 of in Sprechen sie attisch? simply gives


Gestern abend [yesterday evening] ἑσπέρας.

The Italian translation of Enrico Renna and Claudio Ferone has

Ieri sera (ἐχθές) ἑσπέρας

Can just ἑσπέρας mean yesterday evening and is ἐχθές optional?

Like you, I’m not finding anything in LSJ. But I suspect that with an aorist verb, in the right context, ἑσπέρας could be interpreted to mean “yesterday evening” without χθες. I’d like to see an instance from a real ancient Greek text, though.

I found these examples:

Aristoph. Eccl. 41.
καὶ πάνυ ταλαιπώρως ἔγωγ᾽ ὦ φιλτάτη
55 ἐκδρᾶσα παρέδυν. ὁ γὰρ ἀνὴρ τὴν νύχθ᾽ ὅλην
ἔβηττε τριχίδων ἑσπέρας ἐμπλήμενος



Aristoph. Lys. 403
‘ὦ χρυσοχόε τὸν ὅρμον ὃν ἐπεσκεύασας,
ὀρχουμένης μου τῆς γυναικὸς ἑσπέρας
410 ἡ βάλανος ἐκπέπτωκεν ἐκ τοῦ τρήματος.



Aristoph. Peace 200
οὐκ οἶδα πλὴν ἕν, ὅτι θυείαν ἑσπέρας
ὑπερφυᾶ τὸ μέγεθος εἰσηνέγκατο.

All are good.

Thank you, Hylander!
