²Theory of an “elaborate refutation” of Archidamus by Diocles, II, p. 364. See also on Frr 51a–d (anomalia general cause of disease) or on Fr 40, which is guided by a systematic demarcation between two main hermeneutic tasks: finding out which parts purport to reproduce Diocles and evaluating the reliability of what is attributed to him. Van der Eijk shows, very plausibly, how the doxographer has fabricated a “refutation” of Herophilus and other post-Dioclean authorities, which he attributes to Diocles. But I doubt that the refutation draws on “ingredients which, each individually, derive from Diocles’ thought” (pp. 84–5). General beliefs in the existence of four humours or pneuma are too vague; what would be needed is some specific view on them, especially on pneuma in relation to seed theory. The only possible Dioclean “ingredient” confirmed by another source, the view that seed originates in the brain and spinal marrow (cf Frr 41a and b), is annulled by the fact that the Anonymous also attributes to Diocles the rival view that seed originates in nutriment (pp. 30–31).
