 Diogenes Laertius says that Philolaus was from the Greek city of Croton in southern Italy, but our earliest sources are divided as to his city or origin. In his history of medicine, Aristotle’s pupil Meno, who had access to Philolaus’ book, also says that Philolaus was from Croton (DK 44 A27), but another of Aristotle’s pupils, Aristoxenus, who had close connections to the Pythagoreans, presents Philolaus as from another Greek city in southern Italy, Tarentum (D. L. VIII 46, see also Iamblichus, VP 267, which probably derives from Aristoxenus). Perhaps the best way to solve the conflict is to suppose that Philolaus originally came from Croton and that, following attacks on the Pythagoreans in other southern Italian cities ca. 450 and his trip to Thebes in the late 400s, he may have settled in Tarentum late in his life. He is reported to have been the teacher of Archytas of Tarentum in one source (Cicero, de Orat. III 34.139).
