τὸν δὲ πόλεμον τοῦτον, ὃν ἐπολέμησαν Ἀργεῖοι, νομίζω πάντων, ὅσοι πρὸς Ἕλληνας ἐπὶ τῶν καλουμένων ἡρώων ἐπολεμήθησαν ὑπὸ Ἑλλήνων, γενέσθαι λόγου μάλιστα ἄξιον. ὁ μέν γε Ἐλευσινίων πρὸς Ἀθηναίους τοὺς ἄλλους, ὡσαύτως δὲ καὶ Θηβαίων πρὸς Μινύας, τήν τε ἔφοδον διʼ ὀλίγου τῶν ἐπιστρατευσαμένων καὶ ἐν μάχῃ παρέσχοντο μιᾷ τὴν κρίσιν, ἐς ὁμολογίας τε αὐτίκα ἐτράποντο καὶ σπονδάς·
ὁ δὲ Ἀργείων στρατὸς ἐς Βοιωτίαν τε μέσην ἀφίκετο ἐκ μέσης Πελοποννήσου καὶ ὁ Ἄδραστος ἐξ Ἀρκαδίας καὶ παρὰ Μεσσηνίων συμμαχικὰ ἤθροισεν, ὡσαύτως δὲ καὶ τοῖς Θηβαίοις μισθοφορικὰ ἦλθε παρὰ Φωκέων καὶ ἐκ τῆς Μινυάδος χώρας οἱ Φλεγύαι. γενομένης δὲ πρὸς τῷ Ἰσμηνίῳ μάχης ἐκρατήθησαν οἱ Θηβαῖοι τῇ συμβολῇ, καὶ ὡς ἐτράποντο, καταφεύγουσιν ἐς τὸ τεῖχος·
ἅτε δὲ οὐκ ἐπισταμένων τῶν Πελοποννησίων μάχεσθαι πρὸς τὸ τεῖχος, ποιουμένων δὲ θυμῷ μᾶλλον ἢ σὺν ἐπιστήμῃ τὰς προσβολάς, πολλοὺς μὲν ἀπὸ τοῦ τείχους βάλλοντες φονεύουσιν αὐτῶν οἱ Θηβαῖοι, κρατοῦσι δὲ ὕστερον καὶ τοὺς ἄλλους ἐπεξελθόντες τεταραγμένοις, ὡς τὸ σύμπαν στράτευμα πλὴν Ἀδράστου φθαρῆναι. ἐγένετο δὲ καὶ αὐτοῖς τὸ ἔργον οὐκ ἄνευ κακῶν μεγάλων, καὶ ἀπʼ ἐκείνου τὴν σὺν ὀλέθρῳ τῶν κρατησάντων Καδμείαν ὀνομάζουσι νίκην.
ἔτεσι δὲ οὐ πολλοῖς ὕστερον ὁμοῦ Θερσάνδρῳ στρατεύουσιν ἐπὶ τὰς Θήβας οὓς Ἐπιγόνους καλοῦσιν Ἕλληνες· δῆλοι δέ εἰσι καὶ τούτοις οὐ τὸ Ἀργολικὸν μόνον οὐδὲ οἱ Μεσσήνιοι καὶ Ἀρκάδες ἠκολουθηκότες, ἀλλὰ καὶ ἔτι ἐκ Κορίνθου καὶ Μεγαρέων ἐπικληθέντες ἐς τὴν συμμαχίαν· ἤμυναν δὲ καὶ Θηβαίοις οἱ πρόσοικοι, καὶ μάχη πρὸς Γλίσαντι ἀπὸ ἀμφοτέρων ἐγένετο ἰσχυρά.
τῶν δὲ Θηβαίων οἱ μὲν αὐτίκα ὡς ἡττήθησαν ὁμοῦ Λαοδάμαντι ἐκδιδράσκουσιν, οἱ δὲ ὑπολειφθέντες πολιορκίᾳ παρέστησαν. ἐποιήθη δὲ ἐς τὸν πόλεμον τοῦτον καὶ ἔπη Θηβαΐς· τὰ δὲ ἔπη ταῦτα Καλλῖνος ἀφικόμενος αὐτῶν ἐς μνήμην ἔφησεν Ὅμηρον τὸν ποιήσαντα εἶναι, Καλλίνῳ δὲ πολλοί τε καὶ ἄξιοι λόγου κατὰ ταὐτὰ ἔγνωσαν· ἐγὼ δὲ τὴν ποίησιν ταύτην μετά γε Ἰλιάδα καὶ τὰ ἔπη τὰ ἐς Ὀδυσσέα ἐπαινῶ μάλιστα. πολέμου μὲν δή, ὃν Ἀργεῖοι καὶ Θηβαῖοι τῶν Οἰδίποδος παίδων ἕνεκα ἐπολέμησαν, ἐς τοσόνδε ἔστω μνήμη·
I consider that this war which the Argives waged was the most memorable of all the wars carried on by Greeks against Greeks in what they call the heroic age. In the war of the Eleusinians against the rest of the Athenians, and also in the war of the Thebans against the Minyans, the assailants had to go but a little way to find the enemy, a single battle decided the issue, and a peace was immediately ratified. But the Argive army came from the heart of Peloponnese and penetrated into the heart of Boeotia, and Adrastus collected contingents from Arcadia and Messenia. Similarly the Thebans were joined by mercenaries from Phocis, and by the Phlegyans who came from the Minyan territory. A battle took place at the Ismenian sanctuary, the Thebans were defeated in the engagement, and being routed took refuge within the walls of the city. But as the Peloponnesians, not understanding the art of attacking fortifications, pushed their assaults with more courage than science, the Thebans knocked over a great many of them from the walls, and then, before they recovered from their confusion, sallied out and defeated the remainder, so that the whole army, except Adrastus, was cut off. The Thebans themselves suffered heavily in the action, and from that time a victory which proves fatal to the victors has been called a Cadmean victory.
Not many years afterwards the Epigoni (‘after-born’), as the Greeks call them, marched with Thersander against Thebes. It is plain that they too were accompanied not by Argives only, and Messenians, and Arcadians, but also by allies from Corinth and Megara, whom they had invited to join them. On their side the Thebans were supported by their neighbours, and a fierce battle took place at Glisas. The Thebans were worsted, whereupon some of them fled with Laodamas, others stayed behind, were besieged, and taken.
This war is the subject of the epic poem the Thebaid. Callinus, after mentioning the poem, says that the author was Homer, and many respectable persons have shared his opinion. Next to the Iliad and Odyssey there is certainly no poem which I esteem so highly. So much for the war waged by the Argives and Thebans on account of the sons of Oedipus.
