 In the ancient sources, Eurytus is most frequently mentioned in the same breath as Philolaus, and he is probably the student of Philolaus (Iamblichus, VP 148, 139). Aristoxenus (4th c. BCE) presents Philolaus and Eurytus as the teachers of the last generation of Pythagoreans (Diogenes Laertius VIII 46) and Diogenes Laertius reports that Plato came to Italy to meet Philolaus and Eurytus after the death of Socrates (III 46). In order to be the pupil of Philolaus, who was born around 470, and teach the last generation of Pythagoreans around 400, Eurytus would need to be born between 450 and 440. The sources are very confused as to which S. Italian city he was from, Croton (Iamblichus, VP 148), Tarentum (Iamblichus, VP 267; Diogenes Laertius VIII 46) or Metapontum (Iamblichus, VP 266 and 267). It may be that the Eurytus from Metapontum is a different Eurytus. It is possible that Archytas studied with Eurytus, since Theophrastus (Aristotle’s successor in the Lyceum) cites Archytas as the source for the one testimony we have about the philosophy of Eurytus (Metaph. 6a 19–22). In the catalogue of Pythagoreans at the end of Iamblichus’ On the Pythagorean Life (267), Eurytus appears between Philolaus and Archytas in the list of Pythagoreans from Tarentum, which may thus suggest that he was regarded as the pupil of Philolaus and a teacher of Archytas.
