Passage 8.51.8
Λυκόρτας δὲ μετʼ οὐ πολὺ ἀθροίσας ἔκ τε Ἀρκαδίας καὶ παρʼ Ἀχαιῶν δύναμιν ἐστράτευσεν ἐπὶ Μεσσήνην· καὶ ὁ δῆμος αὐτίκα ὁ τῶν Μεσσηνίων προσεχώρησε τοῖς Ἀρκάσι, καὶ οἱ Φιλοποίμενι αἰτίαν θανάτου παρασχόντες ἁλόντες πλὴν Δεινοκράτους ὑπέσχον τιμωρίαν οἱ ἄλλοι, Δεινοκράτης δὲ ἀφίησιν αὐτοχειρίᾳ τὴν ψυχήν. κατάγουσι δὲ καὶ ἐς Μεγάλην πόλιν τοῦ Φιλοποίμενος τὰ ὀστᾶ οἱ Ἀρκάδες.
Not long after, Lycortas gathered a force from Arcadia as well as from among the Achaeans and marched against Messene. Immediately, the people of Messene sided with the Arcadians; and those responsible for bringing about the death of Philopoemen were captured, and with the exception of Deinocrates, the rest suffered punishment. Deinocrates, however, took his own life. Moreover, the Arcadians brought back the bones of Philopoemen to Megalopolis.
