Passage 8.49.2
τὰ μὲν δὴ ἐς γένους δόξαν ὁ πατήρ οἱ Κραῦγις Ἀρκάδων ἐλείπετο οὐδενὸς τῶν ἐν Μεγάλῃ πόλει· τελευτήσαντος δὲ τοῦ Κραύγιδος ἐπὶ παιδὶ ἔτι νηπίῳ τῷ Φιλοποίμενι, ἐπετρόπευσεν αὐτὸν ἀνὴρ Μαντινεὺς Κλέανδρος, φεύγων μὲν ἐκ Μαντινείας καὶ ἐν Μεγάλῃ πόλει μετοικῶν κατὰ τὴν οἴκοθεν συμφοράν, ξενίας δὲ ὑπαρχούσης αὐτῷ πατρικῆς ἐς οἶκον τὸν Κραύγιδος. διδασκάλοις δὲ ὁμιλῆσαι τὸν Φιλοποίμενα καὶ ἄλλοις καὶ Μεγαλοφάνει τε καὶ Ἐκδήλῳ λέγουσι· τοὺς δὲ Ἀρκεσιλάου φασὶν εἶναι Πιταναίου μαθητάς.
As regards noble lineage, Philopoemen's father Kraugis was second to none among the Arcadians at Megalopolis. But when Kraugis died while Philopoemen was still an infant boy, a Mantinean named Cleander served as his guardian, a man who had fled Mantinea and settled in Megalopolis owing to a domestic misfortune, and who had previous guest-friendship ties with the household of Kraugis. It is said that Philopoemen studied under various teachers, among whom were Megalophanes and Ecdelus; these men are said to have been pupils of Arcesilaus of Pitane.
