21st Century Classical Greek -- a bunch of idioms

Book I section 31.  This section gets us to some speech-making that is impoprtant for the grammar. Otherwise it’s quite straightforward. Notice a couple of idioms, orgi ferontes and genitai thesthai.

τὸν δ᾽ ἐνιαυτὸν πάντα τὸν μετὰ τὴν ναυμαχίαν καὶ τὸν ὕστερον οἱ Κορίνθιοι ὀργῇ φέροντες τὸν πρὸς Κερκυραίους πόλεμον ἐναυπηγοῦντο καὶ παρεσκευάζοντο τὰ κράτιστα νεῶν στόλον, ἔκ τε αὐτῆς Πελοποννήσου ἀγείροντες καὶ τῆς ἄλλης Ἑλλάδος ἐρέτας, μισθῷ πείθοντες.

[2] πυνθανόμενοι δὲ οἱ Κερκυραῖοι τὴν παρασκευὴν αὐτῶν ἐφοβοῦντο, καί (ἦσαν γὰρ οὐδενὸς Ἑλλήνων ἔνσπονδοι οὐδὲ ἐσεγράψαντο ἑαυτοὺς οὔτε ἐς τὰς Ἀθηναίων σπονδὰς οὔτε ἐς τὰς Λακεδαιμονίων) ἔδοξεν αὐτοῖς ἐλθοῦσιν ὡς τοὺς Ἀθηναίους ξυμμάχους γενέσθαι καὶ ὠφελίαν τινὰ πειρᾶσθαι ἀπ᾽ αὐτῶν εὑρίσκεσθαι.

[3] οἱ δὲ Κορίνθιοι πυθόμενοι ταῦτα ἦλθον καὶ αὐτοὶ ἐς τὰς Ἀθήνας πρεσβευσόμενοι, ὅπως μὴ σφίσι πρὸς τῷ Κερκυραίων ναυτικῷ καὶ τὸ αὐτῶν προσγενόμενον ἐμπόδιον γένηται θέσθαι τὸν πόλεμον ᾗ βούλονται.

[4] καταστάσης δὲ ἐκκλησίας ἐς ἀντιλογίαν ἦλθον, καὶ οἱ μὲν Κερκυραῖοι ἔλεξαν τοιάδε.

The verbs I bolded in subsections 2 and 3 are different versions of the same verb. Both are personal gerundives, in base voice of course. The first is progressive conceptual, the second is imperfective eventive. What’s the difference?

The Kerkyraeans knew perfectly well that they were in the given situation, belonging neither to the Hellenic nor the Athinaian treaty. This had been true, as we will see, for some time.

The Korinthians found out what the Kerkyraeans were doing, and decided to get their own licks in.

The imperfective in subsection 3 looks weird because not only is there no sigma in it, but it also drops a nu.

Jowett misses that kratista in subsection 1 is a superlative.

Notice the hopos clause in subsection 3.

ὅπως μὴ σφίσι πρὸς τῷ Κερκυραίων ναυτικῷ καὶ τὸ αὐτῶν προσγενόμενον ἐμπόδιον γένηται θέσθαι τὸν πόλεμον ᾗ βούλονται.

“…so that not against themselves on the part of the fleet of the Kerkyraeans and those of them happening to be an obstruction, would there happen the war that they had in prospect.”

Empodion is a problem on Perseus. In the online Middle Liddell, which is a later version, empodion clearly is an obstruction.

The purpose is to keep the Athinaians from joining the Kerkyraeans against the Korinthians.
