535 This was, in fact, a disputed subject: some insisted that Pythagoras left no writings (Porphyry, Vit. Pyth. 57), others listed his works (Diogenes Laertius 8.6-7; cf. Iamblichus, Vit. Pyth. 146). In 1.14 Josephus had numbered Pythagoras among the oldest Greek writers, while noting scepticism on this topic. Here he needs to be dogmatic in denying the existence of authentic works, so that Hermippus can appear not a secondary source but the best available representative of Pythagoras’ views.
