536 Hermippus was not well-known to educated Romans (among the very scanty references, Pliny,
Nat. 30.4, refers to him as a writer on magic), and has to be given special praise here as the only source on Pythagoras whom Josephus can use. Josephus does not date or place him, perhaps from ignorance; his date (second half of the 3rd century BCE) would indicate how large a gap stood between him and Pythagoras. The fragments of his work are collected in
FGH IVA (= Bollansée 1999). A disciple of Callimachus in
Alexandria, he wrote biographies of philosophers and legislators, and not always in flattering terms. The detailed information in the next section may suggest, but does not prove, that Josephus draws directly from Hermippus.
