§7.4.1ἀποδέξας δὲ βασιλέα Πέρσῃσι Ξέρξεα Δαρεῖος ὁρμᾶτο στρατεύεσθαι.
Having declared Xerxes king for the Persians, Darius was eager to set out on his campaign.
ἀλλὰ γὰρ μετὰ ταῦτά τε καὶ Αἰγύπτου ἀπόστασιν τῷ ὑστέρῳ ἔτεϊ παρασκευαζόμενον συνήνεικε αὐτὸν Δαρεῖον, βασιλεύσαντα τὰ πάντα ἕξ τε καὶ τριήκοντα ἔτεα, ἀποθανεῖν, οὐδέ οἱ ἐξεγένετο οὔτε τοὺς ἀπεστεῶτας Αἰγυπτίους οὔτε Ἀθηναίους τιμωρήσασθαι.
However, in the year after these events and the rebellion of Egypt, while he was making preparations, it happened that Darius himself died, after having reigned for thirty-six years in all; and it was not granted to him to punish either the rebellious Egyptians or the Athenians.
