II. Biographical Doxographers

13. 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 fragments of the pseudo-Plutarchean Stromateis, quoted by Eusebios in his Praeparatio Evangelica, come from a source similar to that of the best portions of the Philosophoumena. So far as we can judge, they differ chiefly in two points. In the first place, they are mostly taken from the earliest sections of the work, and therefore most of them deal with the primary substance, the heavenly bodies and the earth. In the second place, the language is a much less faithful transcript of the original.

15. The scrap-book which goes by the name of Diogenes Laertios, or Laertios Diogenes (cf. Usener, Epicurea, pp. 1 sqq.), 425contains large fragments of two distinct doxographies. One is of the merely biographical, anecdotic, and apophthegmatic kind used by Hippolytos in his first four chapters; the other is of a better class, more like the source of Hippolytos’ remaining chapters. An attempt is made to disguise this “contamination” by referring to the first doxography as a “summary” (κεφαλαιωδής) account, while the second is called “particular” (ἐπὶ μέρους).

16. Short doxographical summaries are to be found in Eusebios (P. E. x., xiv., xv.), Theodoret (Gr. aff. cur. ii. 9-11), Irenæus (C. haer. ii. 14), Arnobius (Adv. nat. ii. 9), Augustine (Civ. Dei, viii. 2). These depend mainly upon the writers of “Successions,” whom we shall have to consider in the next section.
