case enable us to verify the exact words of Theophrastos (Chap. I. p. 50, n. 4). The doxography has come through the hands of Kleitomachos, who succeeded Karneades in the headship of the Academy (129 B.C.).
(b) Doxography of the "De natura deorum."—A fresh light was thrown upon this important passage by the discovery at Herculaneum of a roll containing fragments of an Epicurean treatise, so like it as to be at once regarded as its original. This treatise was at first ascribed to Phaidros, on the ground of the reference in Epp. ad Att. xiii. 39. 2; but the real title, Φιλοδήμου περὶ εὐσεβείας, was afterwards restored (Dox. p. 530). Diels, however, has shown (Dox. pp. 122 sqq.) that there is much to be said for the view that Cicero did not copy Philodemos, but that both drew from a common source (no doubt Phaidros, Περὶ θεῶν) which itself went back to a Stoic epitome of Theophrastos. The passage of Cicero and the relevant fragments of Philodemos are edited in parallel columns by Diels (Dox. pp. 531 sqq.).
II. Biographical Doxographers
13.Hippolytos Of the "biographical doxographies," the most: important is Book I. of the Refutation of all Heresies by Hippolytos. This had long been known as the Philosophoumena of Origen; but the discovery of the remaining books, which were first published at Oxford in 1854, showed finally that it could not belong to him. It is drawn mainly from some good epitome of Theophrastos, in which the matter was already rearranged under the names of the various philosophers. We must note, however, that the sections dealing with Thales, Pythagoras, Herakleitos, and Empedokles come from an inferior source, some merely biographical compendium full of apocryphal anecdotes and doubtful statements.
14.The Stromateis. The fragments of the pseudo-Plutarchean Stromateis, quoted by Eusebios in his Praeparatio Evangelica, come from
