§7.3.1Δαρείου δὲ οὐκ ἀποδεικνυμένου κω γνώμην, ἐτύγχανε κατὰ τὠυτὸ τούτοισι καὶ Δημάρητος ὁ Ἀρίστωνος ἀναβεβηκὼς ἐς Σοῦσα, ἐστερημένος τε τῆς ἐν Σπάρτῃ βασιληίης καὶ φυγὴν ἐπιβαλὼν ἑωυτῷ ἐκ Λακεδαίμονος.
While Darius was not yet declaring his decision, Demaratus, the son of Ariston, happened to have come up to Susa at this very same time, having been deprived of the kingship in Sparta and having imposed exile upon himself from Lacedaemon.
§7.3.2οὗτος ὡνὴρ πυθόμενος τῶν Δαρείου παίδων τὴν διαφορήν, ἐλθών, ὡς ἡ φάτις μιν ἔχει, Ξέρξῃ συνεβούλευε λέγειν πρὸς τοῖσι ἔλεγε ἔπεσι, ὡς αὐτὸς μὲν γένοιτο Δαρείῳ ἤδη βασιλεύοντι καὶ ἔχοντι τὸ Περσέων κράτος, Ἀρτοβαζάνης δὲ ἔτι ἰδιώτῃ ἐόντι Δαρείῳ·
This man, having learned of the dispute among Darius's sons, came and, as the story goes, advised Xerxes to say, in addition to the arguments he was already making, that he himself was born to Darius when the latter was already king and held the power of the Persians, whereas Artobazanes was born to Darius when he was still a private citizen.
§7.3.3οὔκων οὔτε οἰκὸς εἴη οὔτε δίκαιον ἄλλον τινὰ τὸ γέρας ἔχειν πρὸ ἑωυτοῦ· ἐπεί γε καὶ ἐν Σπάρτῃ ἔφη ὁ Δημάρητος ὑποτιθέμενος οὕτω νομίζεσθαι, ἢν οἳ μὲν προγεγονότες ἔωσι πρὶν ἢ τὸν πατέρα σφέων βασιλεῦσαι, ὁ δὲ βασιλεύοντι ὀψίγονος ἐπιγένηται, τοῦ ἐπιγενομένου τὴν ἔκδεξιν τῆς βασιληίης γίνεσθαι.
Therefore, it was neither reasonable nor just for anyone else to have the prize of honor instead of himself; for Demaratus, in suggesting this, said that it was also the custom in Sparta that if there were children born before their father became king, and another was born later to him when he was reigning, the succession to the kingship should belong to the one born later.
§7.3.4χρησαμένου δὲ Ξέρξεω τῇ Δημαρήτου ὑποθήκῃ, γνοὺς ὁ Δαρεῖος ὡς λέγοι δίκαια βασιλέα μιν ἀπέδεξε.
When Xerxes made use of Demaratus's advice, Darius, realizing that he spoke what was right, declared him king.
δοκέειν δέ μοι, καὶ ἄνευ ταύτης τῆς ὑποθήκης βασιλεῦσαι ἂν Ξέρξης· ἡ γὰρ Ἄτοσσα εἶχε τὸ πᾶν κράτος.
But in my opinion, even without this advice, Xerxes would have become king; for Atossa held the entire power.
