 There no good reason to think that Democedes (DK I 110–112), the physician from Croton, was himself a Pythagorean, although he had some Pythagorean connections. He is famous from Herodotus’ account (III 125 ff.) of his service to the tyrant, Polycrates, and the Persian king, Darius. One late source names him a Pythagorean (DK I 112.21). Iamblichus mentions a Pythagorean named Democedes, who was involved in the political turmoil surrounding the conspiracy of Cylon against the Pythagoreans, but it is far from clear that this was the physician (VP 257–261). Herodotus never calls Democedes a Pythagorean nor do any other of the later sources (e.g., Aelian, Athenaeus, the Suda), nor does he appear in Iamblichus’ catalogue. A Calliphon, who could be Democedes’ father, is presented as an associate of Pythagoras by Hermippus (DK I 111.36 ff.) and appears in Iamblichus’ catalogue, so it is reasonable to regard him as a Pythagorean, although we know nothing more of him. It is reported (Herodotus III 137) that Democedes married the daughter of the Olympic victor, Milon, who was the Pythagorean, whose house was used as a meeting place (Iamblichus, VP 249). It was undoubtedly because Democedes came from Croton at roughly the time when Pythagoras was prominent there and because of the Pythagorean connections of his father and father-in-law that late sources came to label Democedes himself a Pythagorean. For an argument that Democedes was a Pythagorean see Zhmud 2012a, 120.
