Ἀγησιπόλιδος δὲ ἄπαιδος τελευτήσαντος ἐς Κλεόμβροτον περιῆλθεν ἡ ἀρχή, καὶ ὑπὸ ἡγεμόνι τούτῳ Βοιωτοῖς ἐναντία ἠγωνίσαντο ἐν Λεύκτροις· Κλεόμβροτος δὲ αὐτὸς γενόμενος ἀνὴρ ἀγαθὸς ἀρχομένης ἔτι ἔπεσε τῆς μάχης. μάλιστα δέ πως ἐπὶ πταίσμασιν ἐθέλει μεγάλοις προαφαιρεῖσθαι τὸν ἡγεμόνα ὁ δαίμων, καθὰ δὴ καὶ Ἀθηναίων ἀπῆγεν Ἱπποκράτην τε τὸν Ἀρίφρονος στρατηγοῦντα ἐπὶ Δηλίῳ καὶ ὕστερον ἐν Θεσσαλίᾳ Λεωσθένην.
Κλεομβρότου δὲ ὁ μὲν πρεσβύτερος τῶν παίδων Ἀγησίπολις παρέσχετο μέγα οὐδὲν ἐς μνήμην, Κλεομένης δὲ ὁ νεώτερος μετὰ τὸν ἀδελφὸν τελευτήσαντα ἔσχε τὴν ἀρχήν. γενομένων δὲ αὐτῷ παίδων Ἀκροτάτου καὶ ἐπʼ αὐτῷ Κλεωνύμου κατήγαγε τὸ χρεὼν Ἀκρότατον ἔτι πρότερον ἢ αὐτὸν Κλεομένην, καὶ ὡς Κλεομένης ἀπέθανεν ὕστερον, ἐς ἀντιλογίαν ἀφίκοντο ὑπὲρ τῆς βασιλείας Κλεώνυμός τε ὁ Κλεομένους καὶ Ἀρεὺς ὁ Ἀκροτάτου. δικάζουσιν οὖν οἱ γέροντες Ἀρεῖ τῷ Ἀκροτάτου καὶ οὐχὶ Κλεωνύμῳ πατρῴαν εἶναι τὴν τιμήν.
Κλεωνύμῳ δὲ ἀπελαθέντι τῆς βασιλείας περισσῶς δή τι ὁ θυμὸς ᾤδει, καὶ αὐτὸν οἱ ἔφοροι καὶ ἄλλοις γέρασι ψυχαγωγοῦντες καὶ ἐπὶ ταῖς δυνάμεσιν ἐφιστάντες ἄρχοντα παρῆγον μή ποτε πολέμιον γενέσθαι τῇ Σπάρτῃ. τέλος δὲ ὁ μὲν πολλά τε καὶ ἐχθρὰ ἐς τὴν πατρίδα ἐτόλμησε καὶ Πύρρον τὸν Αἰακίδου σφίσιν ἐπηγάγετο ἐς τὴν χώραν·
Ἀρέως δὲ ἐν Σπάρτῃ τοῦ Ἀκροτάτου βασιλεύοντος Ἀντίγονος ὁ Δημητρίου πεζῷ τε καὶ ναυσὶν ἐπὶ Ἀθήνας στρατεύει. τοῖς δὲ Ἀθηναίοις ἀμυνοῦντες ἀφίκοντο μὲν ὁ Αἰγυπτίων ὁμοῦ Πατρόκλῳ στόλος, ἐξίασι δὲ καὶ οἱ Λακεδαιμόνιοι πανδημεί, τὸν βασιλέα ἡγεῖσθαί σφισιν Ἀρέα ἐπιτάξαντες.
περικαθημένου δὲ Ἀντιγόνου τὰς Ἀθήνας καὶ τῆς ἐσόδου τῆς ἐς τὴν πόλιν τὰ Ἀθηναίων συμμαχικὰ εἴργοντος, Πάτροκλος ἀποστέλλων ἀγγέλους προέτρεπε Λακεδαιμονίους καὶ Ἀρέα ἄρχειν πρὸς Ἀντίγονον μάχης, ἐκείνων δὲ ἀρξάντων οὕτω καὶ αὐτὸς κατὰ νώτου τοῖς Μακεδόσιν ἔφασκεν ἐπικείσεσθαι· πρότερον δὲ οὐκ εἰκὸς εἶναι σφᾶς Αἰγυπτίους τε ὄντας καὶ ναύτας Μακεδόσιν ἐπιέναι πεζῇ. Λακεδαιμόνιοι μὲν δὴ παρακινδυνεύειν ὥρμηντο Ἀθηναίων τε εὐνοίᾳ καί τι καὶ ἄξιον μνήμης ἐς τοὺς ἔπειτα ἐργάσασθαι προθυμούμενοι·
Ἀρεὺς δέ, ὥς σφισι τὰ ἐπιτήδεια ἐξανήλωτο, ἀπῆγεν ὀπίσω τὴν στρατιάν. ταμιεύεσθαι γὰρ τὴν ἀπόνοιαν ἐς τὰ οἰκεῖα ἠξίου καὶ μὴ ἀφειδῶς ἐπʼ ἀλλοτρίοις ἀναρρῖψαι. τοῖς δὲ Ἀθηναίοις ἀντισχοῦσιν ἐπὶ μακρότατον ἐποιήσατο Ἀντίγονος εἰρήνην, ἐφʼ ᾧ τέ σφισιν ἐπαγάγῃ φρουρὰν ἐς τὸ Μουσεῖον. καὶ τοῖς μὲν ἀνὰ χρόνον αὐτὸς ἐξήγαγεν ἑκουσίως τὴν φρουρὰν ὁ Ἀντίγονος, Ἀρέως δὲ ἐγένετο υἱὸς Ἀκρότατος, τοῦ δὲ Ἀρεύς, ὃς ὀκτὼ μάλιστα ἔτη γεγονὼς τελευτᾷ νόσῳ.
καὶ ἐλείπετο γὰρ τῆς Εὐρυσθένους οἰκίας γένος τὸ πρὸς ἀνδρῶν Λεωνίδας ὁ Κλεωνύμου, παντάπασιν ἤδη γέρων· τούτῳ δὴ διδόασιν οἱ Λακεδαιμόνιοι τὴν ἀρχὴν. τῷ δὲ Λεωνίδᾳ διάφορος ἐτύγχανεν ὢν ἐς τὰ μάλιστα Λύσανδρος, ἀπόγονος Λυσάνδρου τοῦ Ἀριστοκρίτου. οὗτος προσποιεῖται Κλεόμβροτον θυγατέρα ἔχοντα Λεωνίδου· τοῦτον δὲ οἰκειωσάμενος ἐπῆγε Λεωνίδᾳ καὶ ἄλλα ἐγκλήματα καὶ ὅρκους αὐτὸν Κλεωνύμῳ τῷ πατρὶ ὀμόσαι παῖδα ὄντα ἐπὶ ὀλέθρῳ τῆς Σπάρτης.
ἐπαύσθη τε δὴ Λεωνίδας βασιλείας καὶ ἀντʼ αὐτοῦ Κλεόμβροτος ἔσχε τὴν τιμήν. εἰ μὲν δὴ ὁ Λεωνίδας ἐπέτρεψε τῷ θυμῷ καὶ Δημαράτῳ τῷ Ἀρίστωνος κατὰ ταὐτὰ ἀπεχώρησεν ἤτοι παρὰ τὸν ἐν Μακεδονίᾳ βασιλεύοντα ἢ τὸν Αἰγύπτιον, ὁ δὲ καὶ μεταγνόντων ἂν Σπαρτιατῶν ὤνατο οὐδέν· νῦν δὲ ἐπιβαλόντων οἱ φυγὴν τῶν πολιτῶν ἀφίκετο ἐς Ἀρκαδίαν, ἐκεῖθεν δὲ ἔτεσιν ὕστερον οὐ πολλοῖς κατάγουσί τε αὐτὸν Λακεδαιμόνιοι καὶ αὖθις βασιλέα ἐποιήσαντο.
Κλεομένει δὲ τῷ Λεωνίδους τά τε ἄλλα ὁποῖα ἐς τόλμαν ὁμοῦ καὶ ἀνδρείαν ὑπῆρξε καὶ ὡς ἐπαύσαντο ἐξ ἐκείνου Σπαρτιᾶται βασιλευόμενοι, πρότερον ἔτι ἐδήλωσέ μοι τὰ ἐς τὸν Σικυώνιον Ἄρατον· προσεπελάβετο δὲ ὁ λόγος μοι καὶ τρόπον ὅντινα ἐν Αἰγύπτῳ Κλεομένης ἐτελεύτησεν.
Agesipolis dying childless, the kingdom devolved on Cleombrotus. Under his command the Lacedaemonians fought the battle of Leuctra against the Boeotians. Cleombrotus behaved himself bravely on that occasion, but fell at the beginning of the battle. It seems to be the will of fate that, when an army is about to sustain a great defeat, the general should be the first to fall. Thus at the battle of Delium the Athenian commander Hippocrates, son of Ariphoron, was cut off; and so at a later time was Leosthenes, another Athenian general, in Thessaly. Of the sons of Cleombrotus, Agesipolis the elder did nothing worthy of record; and when he died his younger brother Cleomenes succeeded to the throne. Two sons were born to Cleomenes, first Acrotatus and next Cleonymus.
Acrotatus died before his father; and on the decease of Cleomenes, a dispute as to the succession arose betwixt Cleonymus, the son of Cleomenes, and Areus, son of Acrotatus. The elders decided that the throne belonged by right of descent to Areus, not to Cleonymus. The heart of Cleonymus swelled high with rage at being excluded from the throne; and to soothe him and reconcile him to his native land, the ephors loaded him with honours, and appointed him to the command of the forces. But it ended in his proving a traitor to his country: amongst his many treasons he induced Pyrrhus the son of Aeacides to invade the land. 3. It was in the reign of Areus, son of Acrotatus, that Antigonus, son of Demetrius, attacked the Athenians by land and sea. Athens was supported by an Egyptian fleet under Patroclus ; and the Lacedaemonians put all their forces into the field, under the command of King Areus, to protect her. But Antigonus drew his lines so closely round the city, that it was impossible for the relieving forces to effect an entrance. In these circumstances, Patroclus sent messengers to Areus urging him to attack Antigonus, and promising to support the attack by falling upon the Macedonian rear. But till that attack was made, Patroclus thought it too much to expect his Egyptian sailors to charge down on Macedonian troops. The Lacedaemonians were eager to be led into action, for they liked the Athenians and thirsted for military glory. But Areus, thinking it a pity to waste so much good courage on other people’s business, resolved to bottle it up and preserve it for home consumption. So when supplies ran short he led his army to the right-about. The Athenians, after holding out for a very long time, were granted peace by Antigonus on condition of allowing him to establish a garrison on the Museum hill; however, in course of time he voluntarily withdrew it. Areus had a son Acrotatus, and he had a son Areus, who sickened and died at the age of eight.
Leonidas, son of Cleonymus, a very old man, was the only surviving descendant of the house of Eurysthenes in the male line ; so the Lacedaemonians gave the kingdom to him. At bitter feud with Leonidas was Lysander, a descendant of Lysander, son of Aristocritus. This Lysander gained over Leonidas’ son-in-law, Cleombrotus ; and having secured him, he brought various charges against Leonidas, amongst others that in his youth he had sworn to his father Cleonymus that he would be the ruin of Sparta. So Leonidas was deposed, and Cleombrotus reigned in his stead. Now, if Leonidas had yielded to passion and gone away like Demaratus, the son of Ariston, to the king of Macedonia or the king of Egypt, it would have profited him nothing if the Spartans had afterwards changed their minds. But as it was, when his countrymen sentenced him to exile, he went to Arcadia, and not many years afterwards the Lacedaemonians brought him back from thence and made him their king again.
The valour and daring of his son Cleomenes have been already described by me in my account of Aratus the Sicyonian, where I also mentioned that after Cleomenes there were no more kings of Sparta. And I recorded besides the manner of his death in Egypt.
