Passage 2.9.3
τῶν δὲ Λεωνίδου παίδων Ἐπικλείδας μὲν ἀπέθανεν ἐν τῇ μάχῃ, Κλεομένην δὲ φεύγοντα ἐς Αἴγυπτον καὶ τιμῆς παρὰ Πτολεμαίῳ πρῶτα ἔχοντα συνέβη δεθῆναι, καταγνωσθέντα Αἰγυπτίων ἄνδρας ἐπὶ τὸν βασιλέα συνιστάναι. καὶ ἀπέδρα μὲν ἐκ τοῦ δεσμωτηρίου καὶ τοῖς Ἀλεξανδρεῦσιν ἀρχὴν θορύβου παρέσχε· τέλος δέ, ὡς ἡλίσκετο, ἀπέσφαξεν αὑτόν. Λακεδαιμόνιοι δὲ ἄσμενοι Κλεομένους ἀπαλλαγέντες βασιλεύεσθαι μὲν οὐκέτι ἠξίωσαν, τὰ δὲ λοιπὰ καὶ ἐς τόδε διαμένει σφίσιν ἐκείνης τῆς πολιτείας. Ἀράτῳ δὲ Ἀντίγονος ἅτε ἀνδρὶ εὐεργέτῃ καὶ συγκατειργασμένῳ λαμπρὰ οὕτω διέμεινεν εὔνους.
Of Leonidas’ sons, Epicleidas died in the battle. Cleomenes fled to Egypt, and although he initially received honor from Ptolemy, he was subsequently imprisoned after being accused of conspiring with Egyptians against the king. He escaped from prison and stirred up unrest among the Alexandrians, but ultimately, when recaptured, he took his own life. The Spartans, relieved to be rid of Cleomenes, no longer desired kingship; instead, the political order they established thereafter endures among them even to this day. Antigonus remained steadfastly favorable toward Aratus, treating him generously as a benefactor and one who had actively shared in his successes.
