§17.1.1ἡ μὲν πρὸ ταύτης βύβλος, οὖσα τῆς ὅλης συντάξεως ἑξκαιδεκάτη, τὴν ἀρχὴν ἔσχεν ἀπὸ τῆς Φιλίππου τοῦ Ἀμύντου βασιλείας· περιελήφθησαν δʼ ἐν αὐτῇ πράξεις αἱ μὲν τοῦ Φιλίππου πᾶσαι μέχρι τῆς τελευτῆς, αἱ δὲ τῶν ἄλλων βασιλέων τε καὶ ἐθνῶν καὶ πόλεων ὅσαι γεγόνασι κατὰ τοὺς τῆς βασιλείας ταύτης χρόνους, ὄντας ἐτῶν εἴκοσι καὶ τεσσάρων.
The book preceding this one, being the sixteenth of the entire work, had its beginning with the reign of Philip, the son of Amyntas; and there were included in it all the deeds of Philip down to his death, and those of the other kings, nations, and cities which occurred during the years of this reign, which were twenty-four.
§17.1.2ἐν ταύτῃ δὲ τὰς συνεχεῖς πράξεις ἀναγράφοντες ἀρξόμεθα μὲν ἀπὸ τῆς Ἀλεξάνδρου βασιλείας, περιλαβόντες δὲ τὰ τούτῳ τῷ βασιλεῖ πραχθέντα μέχρι τῆς τελευτῆς συναναγράψομεν καὶ τὰ ἅμα τούτοις συντελεσθέντα ἐν τοῖς γνωριζομένοις μέρεσι τῆς οἰκουμένης· οὕτω γὰρ μάλιστα ὑπολαμβάνομεν τὰς πράξεις εὐμνημονεύτους ἔσεσθαι, κεφαλαιωδῶς τεθείσας καὶ συνεχὲς ἐχούσας ταῖς ἀρχαῖς τὸ τέλος.
But in this book, in recording the consecutive events, we shall begin with the reign of Alexander, and having embraced the deeds performed by this king down to his death, we shall also record at the same time those accomplished in the known parts of the inhabited world; for in this way we believe that the events will be most easily remembered, being presented summarily and having the end continuous with the beginning.
§17.1.3ἐν ὀλίγῳ δὲ χρόνῳ μεγάλας πράξεις οὗτος ὁ βασιλεὺς κατειργάσατο καὶ διὰ τὴν ἰδίαν σύνεσίν τε καὶ ἀνδρείαν ὑπερεβάλετο τῷ μεγέθει τῶν ἔργων πάντας τοὺς ἐξ αἰῶνος τῇ μνήμῃ παραδεδομένους βασιλεῖς· §17.1.4ἐν ἔτεσι γὰρ δώδεκα καταστρεψάμενος τῆς μὲν Εὐρώπης οὐκ ὀλίγα, τὴν δὲ Ἀσίανσχεδὸν ἅπασαν εἰκότως περιβόητον ἔσχε τὴν δόξαν καὶ τοῖς παλαιοῖς ἥρωσι καὶ ἡμιθέοις ἰσάζουσαν.
For in a short time this king accomplished great deeds, and through his own intelligence and courage surpassed in the magnitude of his works all the kings who have been handed down to memory from all time; since in twelve years, having subdued not a small part of Europe and almost the whole of Asia, he reasonably possessed a far-famed glory and one equal to the ancient heroes and demigods.
ἀλλὰ γὰρ οὐκ ἀναγκαῖον ἡμῖν ἐν τῷ προοιμίῳ προλαμβάνειν τι τῶν κατωρθωμένων τούτῳ τῷ βασιλεῖ· αὐταὶ γὰρ αἱ κατὰ μέρος πράξεις ἱκανῶς μηνύσουσι τὸ μέγεθος τῆς δόξης αὐτοῦ.
But indeed, it is not necessary for us to anticipate in the preface any of the achievements successfully accomplished by this king; for the individual deeds themselves will sufficiently reveal the magnitude of his glory.
§17.1.5Ἀλέξανδρος οὖν γεγονὼς κατὰ πατέρα μὲν ἀφʼ Ἡρακλέους, κατὰ δὲ μητέρα τῶν Αἰακιδῶν οἰκείαν ἔσχε τὴν φύσιν καὶ τὴν ἀρετὴν τῆς τῶν προγόνων εὐδοξίας.
Alexander, therefore, being by his father descended from Heracles and by his mother from the Aeacidae, possessed a nature and virtue suitable to the high reputation of his ancestors.
ἡμεῖς δὲ τοὺς ἁρμόττοντας τῇ γραφῇ χρόνους παραθέντες ἐπὶ τὰς οἰκείας τῆς ὑποκειμένης ἱστορίας πράξεις τρεψόμεθα.
And we, having set down the chronological dates appropriate to the narrative, shall turn to the proper events of the history under consideration.
