Passage 8.49.6
ὁ δὲ καὶ ἐς τοσοῦτο ὅμως πεπεδημένος τά τε γόνατα ἐνέκλινε καὶ ἐς τὸ πρόσω χωρεῖν ἐβιάζετο, ὥστε καὶ ὑπὸ τῶν ποδῶν τοῦ κινήματος τὸ δόρυ ἔκλασεν· ἐπεὶ δὲ οἱ Λακεδαιμόνιοι καὶ ὁ Κλεομένης ἐκρατήθησαν καὶ ἐς τὸ στρατόπεδον ἀνέστρεψε Φιλοποίμην, ἐνταῦθα ἐξ ἀμφοτέρων αὐτοῦ τῶν μηρῶν οἱ ἰατροὶ τῇ μὲν τὸν σαυρωτῆρα ἐξεῖλκον, τῇ δὲ τὴν αἰχμήν. Ἀντίγονος δὲ ὡς ἐπύθετο καὶ εἶδεν αὐτοῦ τὰ τολμήματα, ἐποιεῖτο σπουδὴν ἐπάγεσθαι Φιλοποίμενα ἐς Μακεδονίαν.
Nevertheless, although restrained even to such a degree, he bent his knees and struggled forward with such force that he broke the spear shaft against his legs in the movement. After the Lacedaemonians and Cleomenes were overcome, and Philopoemen had returned to the camp, the physicians removed from both his thighs the spear-tip from one thigh and the butt-spike from the other. When Antigonus learned of this and saw his remarkable bravery, he was eager to persuade Philopoemen to accompany him into Macedonia.
