Cratippus in Wikipedia
Cratippus of Athens
Cratippus (Ancient Greek: Κράτιππος; fl. c. 375 BC), was a Greek historian. There are only three or four references to him in ancient literature, and his importance derives from his being identified by several scholars (e.g. Blass) with the author of the historical fragment discovered by Grenfell and Hunt. The fragment itself was published in Oxyrhynchus Papyri, vol. v, and is known as the Hellenica Oxyrhynchia. 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 BC) down to the Battle of Cnidus.
Cratippus of Pergamon
Cratippus (Greek: Κρατίππος) of Pergamum, was a leading Peripatetic philosopher of the 1st century BC who taught at Mytilene and Athens. The only aspects of his teachings which are known to us are what Cicero records concerning divination.
Cratippus was a contemporary of Cicero who was connected with him by intimate friendship, and entertained a very high opinion of him, for he declared him to be the most distinguished among the Peripatetics that he had known, and thought him at least equal to the greatest men of his school. Cratippus lived for a time at Mytilene, and accompanied Pompey in his flight after the Battle of Pharsalia, endeavouring to comfort and rouse him by philosophical arguments. Several eminent Romans, such as M. Marcellus and Cicero himself, received instruction from him, and in 44 BC Cicero's son was his pupil at Athens, and was tenderly attached to him. Young Cicero seems also to have visited Asia in his company. When Julius Caesar was at the head of the Roman republic, Cicero obtained from him the Roman franchise for Cratippus, and also induced the council of the Areopagus at Athens to invite the philosopher to remain in the city and to continue his instructions in philosophy. Although Cicero speaks of him as the leading philosopher of the Peripatetic school, it is not certain if he was the scholarch. After the murder of Caesar, Brutus, while staying at Athens, also attended the lectures of Cratippus.
Notwithstanding the high opinion which Cicero entertained of the knowledge and talent of Cratippus, we do not hear that he wrote on any philosophical subject, and the only allusions we have to his tenets, refer to his opinions on divination, on which he seems to have written a work. Cicero states that Cratippus believed in dreams and supernatural inspiration (Latin: furor) but that he rejected all other kinds of divination. He seems to have held that, while motion, sense and appetite cannot exist apart from the body, thought reaches its greatest power when most free from bodily influence, and that divination is due to the direct action of the divine mind on that faculty of the human soul which is not dependent on the body.
