§1.23.1τῶν δὲ πρότερον ἔργων μέγιστον ἐπράχθη τὸ Μηδικόν, καὶ τοῦτο ὅμως δυοῖν ναυμαχίαιν καὶ πεζομαχίαιν ταχεῖαν τὴν κρίσιν ἔσχεν.
Of the former achievements, the Persian war was the greatest, yet this came to a speedy decision by two sea-fights and two land-fights.
τούτου δὲ τοῦ πολέμου μῆκός τε μέγα προύβη, παθήματά τε ξυνηνέχθη γενέσθαι ἐν αὐτῷ τῇ Ἑλλάδι οἷα οὐχ ἕτερα ἐν ἴσῳ χρόνῳ.
But of this war both the length went on to a great extent, and sufferings befell Greece in it such as no others in an equal space of time.
§1.23.2οὔτε γὰρ πόλεις τοσαίδε ληφθεῖσαι ἠρημώθησαν, αἱ μὲν ὑπὸ βαρβάρων, αἱ δ’ ὑπὸ σφῶν αὐτῶν ἀντιπολεμούντων (εἰσὶ δ’ αἳ καὶ οἰκήτορας μετέβαλον ἁλισκόμεναι), οὔτε φυγαὶ τοσαίδε ἀνθρώπων καὶ φόνος, ὁ μὲν κατ’ αὐτὸν τὸν πόλεμον, ὁ δὲ διὰ τὸ στασιάζειν.
For neither were so many cities taken and laid waste, some by the barbarians, others by the warring parties themselves (and there were some which even changed their inhabitants upon being captured), nor were there so many banishments of men and slaughter, some in the war itself, some through civil strife.
§1.23.3τά τε πρότερον ἀκοῇ μὲν λεγόμενα, ἔργῳ δὲ σπανιώτερον βεβαιούμενα οὐκ ἄπιστα κατέστη, σεισμῶν τε πέρι, οἳ ἐπὶ πλεῖστον ἅμα μέρος γῆς καὶ ἰσχυρότατοι οἱ αὐτοὶ ἐπέσχον, ἡλίου τε ἐκλείψεις, αἳ πυκνότεραι παρὰ τὰ ἐκ τοῦ πρὶν χρόνου μνημονευόμενα ξυνέβησαν, αὐχμοί τε ἔστι παρ’ οἷς μεγάλοι καὶ ἀπ’ αὐτῶν καὶ λιμοὶ καὶ ἡ οὐχ ἥκιστα βλάψασα καὶ μέρος τι φθείρασα ἡ λοιμώδης νόσος·
And those things which were formerly reported by hearsay, but more rarely confirmed by actual facts, became not incredible: both concerning earthquakes, which at the same time held sway over the greatest part of the earth and were themselves most violent, and eclipses of the sun, which occurred more frequently compared to what was remembered from former times, and great droughts in some quarters, and as a consequence of them, famines, and that which did not least harm and destroyed a certain part of the population, the pestilential disease.
ταῦτα γὰρ πάντα μετὰ τοῦδε τοῦ πολέμου ἅμα ξυνεπέθετο.
For all these things fell upon them together along with this war.
§1.23.4ἤρξαντο δὲ αὐτοῦ Ἀθηναῖοι καὶ Πελοποννήσιοι λύσαντες τὰς τριακοντούτεις σπονδὰς αἳ αὐτοῖς ἐγένοντο μετὰ Εὐβοίας ἅλωσιν.
And the Athenians and Peloponnesians began it by dissolving the thirty years' truce which had been made between them after the capture of Euboea.
§1.23.5διότι δ’ ἔλυσαν, τὰς αἰτίας προύγραψα πρῶτον καὶ τὰς διαφοράς, τοῦ μή τινα ζητῆσαί ποτε ἐξ ὅτου τοσοῦτος πόλεμος τοῖς Ἕλλησι κατέστη.
And as to why they dissolved it, I have first written down the causes and the differences, so that no one should ever have to inquire from what origin so great a war came upon the Greeks.
§1.23.6τὴν μὲν γὰρ ἀληθεστάτην πρόφασιν, ἀφανεστάτην δὲ λόγῳ, τοὺς Ἀθηναίους ἡγοῦμαι μεγάλους γιγνομένους καὶ φόβον παρέχοντας τοῖς Λακεδαιμονίοις ἀναγκάσαι ἐς τὸ πολεμεῖν·
For the truest cause, though least openly expressed in speech, I consider to be that the Athenians, by becoming great and bringing fear to the Lacedaemonians, forced them into war.
αἱ δ’ ἐς τὸ φανερὸν λεγόμεναι αἰτίαι αἵδ’ ἦσαν ἑκατέρων, ἀφ’ ὧν λύσαντες τὰς σπονδὰς ἐς τὸν πόλεμον κατέστησαν.
But the causes openly alleged on both sides were these, starting from which they dissolved the treaty and entered into the war.
