The Peripatetic view of Pythagoras mirrors the split in the tradition that was present in the earliest sources: Aristoxenus of Tarentum follow Empedocles in being overwhelmingly positive, whereas Dicaearchus and Hieronymus are heirs to Heraclitus' bitter critique. In terms of amount of material, the Peripatetics put greatest emphasis on the way of life of Pythagoras and later Pythagoreans. Theophrastus succeeded Aristotle as head of the Lyceum in 322 and remained until 287. He certainly referred to the Pythagoreans in his contribution to the Peripatetic survey of human knowledge, the Physical Opinions, which systematically collected early Greek views about the natural world. A text about the Pythagoreans in the later tradition can, with more or less plausibility, be traced back to Eudemus. Dicaearchus, writing at the same time as Theophrastus, Eudemus and Meno, focuses not on Pythagorean contributions to the sciences but rather on the life of Pythagoras himself.
