CRATIPPUS (fl. c. 375 B.c.), Greek historian. There are only three or four references to him in ancient literature, but he has been identified by several scholars (e.g. Blass) with the author of the historical fragment discovered by Grenfell and Hunt, and published by them in Oxyrhynchus Papyri, vol. v. It may be regarded as a fairly certain inference from a passage in Plutarch (De Gloria Atheniensium, P. 345 E, ed. Bernardakis, ii. P. 455) that he was an Athenian writer, intermediate in date between Thucydides and Xenophon, and that his work continued the narrative of Thucydides, from the point at which the latter historian stopped (410 B.c.) down to the battle of Cnidus (394 B.c.)• The fragments are published in C. Muller's Fragmenta Historicorum Graecorum. For authorities see under THEOPoMPvs.
