§1.118.1μετὰ ταῦτα δὲ ἤδη γίγνεται οὐ πολλοῖς ἔτεσιν ὕστερον τὰ προειρημένα, τά τε Κερκυραϊκὰ καὶ τὰ Ποτειδεατικὰ καὶ ὅσα πρόφασις τοῦδε τοῦ πολέμου κατέστη.
Not many years after these events, there occurred the incidents already mentioned, namely those concerning Corcyra and Potidaea, and all the other things that became the pretext for this war.
§1.118.2ταῦτα δὲ ξύμπαντα ὅσα ἔπραξαν οἱ Ἕλληνες πρός τε ἀλλήλους καὶ τὸν βάρβαρον ἐγένετο ἐν ἔτεσι πεντήκοντα μάλιστα μεταξὺ τῆς τε Ξέρξου ἀναχωρήσεως καὶ τῆς ἀρχῆς τοῦδε τοῦ πολέμου·
All these things which the Greeks did against one another and against the barbarian occurred in a period of about fifty years between the retreat of Xerxes and the beginning of this war.
ἐν οἷς οἱ Ἀθηναῖοι τήν τε ἀρχὴν ἐγκρατεστέραν κατεστήσαντο καὶ αὐτοὶ ἐπὶ μέγα ἐχώρησαν δυνάμεως, οἱ δὲ Λακεδαιμόνιοι αἰσθόμενοι οὔτε ἐκώλυον εἰ μὴ ἐπὶ βραχύ, ἡσύχαζόν τε τὸ πλέον τοῦ χρόνου, ὄντες μὲν καὶ πρὸ τοῦ μὴ ταχεῖς ἰέναι ἐς τοὺς πολέμους, ἢν μὴ ἀναγκάζωνται, τὸ δέ τι καὶ πολέμοις οἰκείοις ἐξειργόμενοι, πρὶν δὴ ἡ δύναμις τῶν Ἀθηναίων σαφῶς ᾔρετο καὶ τῆς ξυμμαχίας αὐτῶν ἥπτοντο.
During this time, the Athenians established their empire more firmly and themselves advanced to a high degree of power, while the Lacedaemonians, although aware of this, did not try to prevent it except to a small extent, and remained quiet for the greater part of the time; for even before this they were not swift to go to war unless they were compelled, and they were also to some extent hindered by domestic wars, until indeed the power of the Athenians was clearly rising and they were laying hands upon their alliance.
τότε δὲ οὐκέτι ἀνασχετὸν ἐποιοῦντο, ἀλλ’ ἐπιχειρητέα ἐδόκει εἶναι πάσῃ προθυμίᾳ καὶ καθαιρετέα ἡ ἰσχύς, ἢν δύνωνται, ἀραμένοις τόνδε τὸν πόλεμον.
Then indeed they thought it was no longer tolerable, but decided that they must attempt with all eagerness to pull down their strength, if they could, by taking up this war.
§1.118.3αὐτοῖς μὲν οὖν τοῖς Λακεδαιμονίοις διέγνωστο λελύσθαι τε τὰς σπονδὰς καὶ τοὺς Ἀθηναίους ἀδικεῖν, πέμψαντες δὲ ἐς Δελφοὺς ἐπηρώτων τὸν θεὸν εἰ πολεμοῦσιν ἄμεινον ἔσται·
Now, the Lacedaemonians themselves had already decided that the treaty was broken and that the Athenians were in the wrong, and sending to Delphi, they asked the god whether it would be better for them if they went to war.
ὁ δὲ ἀνεῖλεν αὐτοῖς, ὡς λέγεται, κατὰ κράτος πολεμοῦσι νίκην ἔσεσθαι, καὶ αὐτὸς ἔφη ξυλλήψεσθαι καὶ παρακαλούμενος καὶ ἄκλητος.
And the god, as it is said, answered them that if they fought with all their might, victory would be theirs, and said that he himself would help them, both when called upon and uncalled.
